T24-ACM, ACMm & ACMi for Load Cell, Strain Gauge Transmitter Enclosures

Q: What is an ACM?

A: An ACM (transmitter connectivity module) is a housing for any T24 transmitter module providing IP67 protection, or higher with specialist glands, along with power and easy to use field terminals for connecting sensors.

Q: What is the difference between the ACM and ACMi?

A: The T24-ACMi is physically smaller and provides power via 2 x AA batteries and has smaller terminal block style field connectors for wiring to transmitter modules. The T24-ACM although larger can provide power from an external power supply (5-18V) as well as 2 x D cell batteries which provide a higher battery capacity allowing for longer battery life.

Q: What transmitter module fits with the ACM and ACMi?

A: When using either ACM you will require an transmitter module that can accept an external antenna denoted by an ‘e’ on the end of the model name. Both ACM’s benefit from being fitted with a T24-ANTA which provides the best omni transmission range although higher gain and more directional antennas such as the T24-ANTC can also be fitted.

T24-BC1 Charger Module

Q: How are the modules powered?

A: The ACMm is the smallest module and has a separate battery pack (T24-BB1 using 2 x AAA). The T24-ACMi is the mid size module and provides power via 2 x AA internal batteries. The T24-ACM although larger can provide power from an external power supply (5-18V) as well as 2 x D cell internal batteries which provide a higher battery capacity allowing for longer battery life.

Q: What sensors would these inputs cover?

A: Any sensor that provides a voltage, current or ratio metric interface can be connected to an transmitter module, including load cells, inclinometers, accelerometers, displacement LVDT, pressure, potentiometer, pulse, temperature, humidity, ph, shock.

Q: Is the system point to point?

A: Yes, however the modules may also operate in many to one (such as multiple data transmitters modules communicating with a base station) and one to many (such as a data transmitter module supplying data to multiple handhelds and displays).

Q: What Frequency does the system operate on?

A: Licence free world wide 2.4GHz, although this frequency is used by other equipment, the T24 range has been tested with Bluetooth, Zigbee & WiFi devices without conflicts.

Q: What limits the RF range of the devices?

A: Any metal surface will reflect 2.4 GHz radio waves, therefore in a sealed metal box, no RF will escape. However by providing a suitable RF window the signals will propagate out. Water and concrete also limit the RF range.

Q: What is the range of T24?

A: The T24-ACMm which has an integral antenna has a range of 400 metres direct line of sight. The T24-ACM / T24-ACMi uses a integrated PCB T24-ANTA antenna provides up to 800 metres range in ideal conditions. This range can be increased up to two times with the T24-AR (wireless range extender).

Q: Can PC software gather data from many devices?

A: Yes, Mantracourt provides freeware for logging up to 100 inputs to one base station, in addition the free Windows DLL and COM driver can be used to gather data through a customer's own PC software.

Q: How many devices can operate on one radio channel?

A: Many devices can operate on the same radio channel depending on the sample rate of the transmitter modules present in the system. The radio channel is capable of supporting up to 200 data packets per second.

Q: What software is provided with the T24 devices?

A: All devices are supported by the T24 Tool Kit which allows users to configure all devices from the T24 range as well as view and log data from transmitters modules in range. The software can also be downloaded directly from our website.

Q: How reliable are the readings?

A: Due to the digital nature of the T24 system, when a reading is received by any device it is guaranteed not have been distorted over the RF transmission.

Q: Is it possible to use wireless range extenders within T24 network?

A: The T24-AR wireless range extender which can be added to the system can propagate a signal around corners and obstacles. This unit can also double the effective range - but only once.

T24-AR Wireless Range Extender

Q: How many T24 Transmitter Modules (Strain, Current, Voltage) can the T24-AR support?

A: Many devices can operate on the same radio channel depending on the sample rate of the transmitter modules present in the system. Therefore each wireless range extender is capable of supporting up to 200 data packets per second, ie. 10 devices at 20 Hz or 20 devices at 10 Hz.

Q: Can I wall mount the T24-AR?

A: Yes, there are 4 mounting holes on the back of the ABS case.

Q: Will the T24-AR work with existing units in the field?

A: The T24-AR is compatible with all units in the field except for T24-HS Handheld Displays manufactured prior to June 2011. The T24-AR will not wake and sleep unless the T24-HS has the 2.1 radio version which is now installed into all T24 equipment. Existing radio modules can be upgraded if required. Please contact Sales for more information. 

Q. Do I need to align the T24-AR in a particular way to get the signal around corners?

A. If the T24-ANTA PCB antenna is fitted to the receiver and transmitter then no special directions are needed except that the T24-AR needs to be in direct line of site of both the transmitting T24 module and the receiving T24 module.

Q: Would the Wireless range extender assist with range if I am using an T24-ANTB or ANTC whip antenna?

A: Yes it would provided all your sensors were in the same horizontal plane. If your sensor and receiver are not in the same horizontal plane this can sometimes lead to alignment issues which can often be resolved by using the T24-ANTA as it can radiate in more directions.

T24-Base Stations

Q: What is the difference between the T24-SO Serial Output and T24 Base Stations?

A: The T24-SO gathers data from up to 8 transmitter modules and, on its serial output, provides a user configurable ASCII string. The output string can contain the summed value of the gathered data. This output can be used to drive serial displays, printers or to simply feed directly into a PC, PLC or other data transmitter systems.
The base stations communicate bi-directionally so are used to configure the devices as well as gather data. The communications protocol is binary and packet based and so requires processing to present the data to the application in a formatted manner.

Q: How many T24 transmitter modules can be controlled by one USB base station at the same time?

A: Transmitter modules are not controlled when providing data, rather data is provided at a user determined rate during configuration set up. The base station can gather data from any number of transmitter modules providing they are on the same channel. The number of modules a single base station can process depends upon the frequency of transmission from the transmitter modules that channel.

Q: Can base stations integrate to other communications protocols?

A: With the use of the .DLL and COM driver provided with the T24 Tool Kit, users can create tunnelling between the data provided by the base station, to the PC, and another communication protocols.

Q: Once a transmitter module has been configured, will it require regular connections to the base station?

A: No. Once a transmitter module has been configured it will remain stable for its lifetime providing its operating limits are not exceeded.

Q: What is the function of the USB and the industrial T24 base stations?

A: Both provide users with a PC interface by which collect data from any transmitter module with in range and configure all devices in the T24 range.

Q: Is the T24-BSue a stock item?

A: Yes

Q: How many transmitter modules can be acquired by the base stations?

A: Each base station can use one of 15 channels. From that selected channel a base station can collect data simultaneously from any number transmitter modules depending upon the frequency of readings being provided by the transmitter module.

Q: How is the industrial base station different to the USB base station?

A: The industrial base station provides not only USB interface but also RS232 and RS485 at multiple baud rates. This module can also be DIN rail mounted.

T24-PA OEM Wireless Sensor Pulse Transmitter

Q: How accurate is the measurement?

A: At a slow input rate of 1Hz the accuracy is 0.15% and at 3Hz the accuracy is 0.25%.  Just under half this error is to allow for temperature drift over the full operating temperature range of the T24-PA device (-40 to +85 degrees) so the accuracy in a stable temperature environment is far better.

Q: What types of inputs can be used?

A: Any volt free contact input such as relays, voltage sources (up to 24 volts) and NPN open collector inputs.

Q: What is the counter, and its maximum value?

A: The counter is a counter which increments every time a pulse is detected either on rising or falling edge which can be set in the tool kit. The maximum value for the counter is 4,294,967,295 at which point the counter will overflow.

Q: How do I reset the counter value of the T24-PA?

A: The counter value can be reset either by contacting the digital input to the ground or by transmitting a data packet with a defined data tag from another device, such as a T24-HA, T24-RM1 or even another T24 transmitter module. This can also be achieved with a power cycle.

Q: How do I calibrate the output?

A: The T24-PA is factory calibrated to the nearest 0.25 μS which provides users with a set of predefined outputs; Hz, RPM and Period. All of these values can have a custom gain and offset applied to them, the resulting output can therefore be in whatever units or range of values you require.

A: The T24-TA can output values in degrees Celsius, degrees Fahrenheit, Kelvin or Ohms.

Q: Is there a way to apply a custom calibration?

A: There is no custom calibration on the T24-TA device however an offset can be applied to any outputted values.

Q: How can I account for long cable length when performing two wire measurements?

A: There is a custom offset that can be used. This can be used to offset a temperature inaccuracy due to long cable lengths when using two or three wire connections.

T24-RA OEM Wireless Potentiometer Sensor Transmitter

Q: What output does the device provide?

A: The T24-RA is factory fitted and calibrated to provide an output between 0-100% as the input value varies between the negative and positive excitation.

Q: How do I calibrate the device?

A: The T24-RA module has a 9 point linearization and calibration feature which allows users to calibrate the percentage output into whatever units are required. For example, calibrating a linear potentiometer would be performed by entering the distances that the plunger you want to measure moves and calibrating at 9 points over that range.

Q: Can I just measure a resistance?

A: The T24-RA is a potentiometer input which means it can not measure resistance directly yet if wired into a potential divider circuit, with a known resistor value, the change in resistance can be measured.

Q: Can I use a rotary input?

A: The T24-RA is designed to work with potentiometer inputs that pass from 0-100%. To avoid the T24-RA providing numbers that are outside the calibrated output the module has a rotary limit. This is the value at which the input is expected to move between the maximum and minimum values.
