This OEM wireless 2 KHz strain gauge sensor transmitter provides high speed measurement of strain gauge, pressure, linear displacement and other bridge based sensors including loadcells. The small module size allows for the option of embedding it within the sensor housing.
Low power modes allow the module to ‘power off’ completely and can be controlled by other T24 products such as the handheld displays or a base station.The high speed electronics deliver low drift results which are transmitted at a rate of 2,000 readings per second to other T24 devices such as analog outputs and base stations etc.
Although this module can be used ‘as is’ for OEM solutions there are a number of enclosure options available. See ‘Related Products’ tab.
Integral antenna option offers up to 600 m (1969 ft) range and external antenna options allows up to 800 m (2600 ft) range in an open field site. The T24-SAf is configured using free T24 Toolkit software which runs on a PC connected to a T24 base station.
The license free 2.4 GHz direct sequence spread spectrum (DSSS) radio technology offers high integrity, error free communications which can co-exist with other wireless technologies such as Wi-Fi, Bluetooth® and Zigbee®. FCC, ETSI and IC approvals.

- Q: What are the sampling rates of the transmitter modules?
-
A: The T24 standard transmitter modules (SA, IA, VA, RA, TA, PA) sample from 0-200 updates/sec. The T24-SA fast transmitter modules are fixed at 2,000 updates/sec.
- Q: What is the resolution of the transmitter modules?
-
A: The noise free resolution for a sample time of 10 milli-seconds or less is 15.5 bits for the T24 SA, 12.5 bits for the T24-VA, 14 bits for the VA and 12.25 bits for the T24IA.
The T24-PA’s accuracy % input error @ 1 Hz is 0.15% and for the T24 RA the accuracy is 0.01% of the full scale.
With increased sample times resolution can be increased up to 18.75 bits for the T24-SA. - Q: What is the supply voltage for the transmitter modules?
-
A: 3V for the transmitter modules and handheld displays. Other modules in the range take 9-36 V.
- Q: What is the difference between the "i" and "e" versions of the transmitter units?
-
A: The ‘i’ modules all feature an on-chip integrated antenna. The ‘e’ modules are fitted with a miniature UFL connector which can be used with any of the antenna options available; the T24-ANTA (PCB antenna) or T24-ANTB (fixed 90 degree Whip antenna) or T24-ANTC (flexible whip antenna).
- Q: How are the modules powered?
-
A: Two standard AA batteries or the T24-BC1 Battery Charger, which provides a re-chargeable power supply using a Li-ion Cell. Find out the battery life of your system using our Battery Calculator.
- 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 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: 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: 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.
- 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: 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.
- 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 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: What is the communication protocol?
-
A: Proprietary protocol based on a 802.15.4 chip. This allows the T24 range to co-exist with Bluetooth, Zigbee & WiFi devices without conflicts.
- Q: What are the sampling rates of the transmitter modules?
-
A: The T24 standard transmitter modules (SA, IA, VA, RA, TA, PA) sample from 0-200 updates/sec. The T24-SA fast transmitter modules are fixed at 2,000 updates/sec.
- Q: What is the resolution of the transmitter modules?
-
A: The noise free resolution for a sample time of 10 milli-seconds or less is 15.5 bits for the T24 SA, 12.5 bits for the T24-VA, 14 bits for the VA and 12.25 bits for the T24IA.
The T24-PA’s accuracy % input error @ 1 Hz is 0.15% and for the T24 RA the accuracy is 0.01% of the full scale.
With increased sample times resolution can be increased up to 18.75 bits for the T24-SA. - Q: What is the supply voltage for the transmitter modules?
-
A: 3V for the transmitter modules and handheld displays. Other modules in the range take 9-36 V.
- 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: Can power be provided to a sensor?
-
A: Yes, all transmitter modules feature a 5V supply which is a excitation voltage (with exception of T24-RA which has 2.5V supply).
- Q: How is the strain gauge transmitter module calibrated?
-
A: The modules are factory calibrated to 2.5 mV/V which can be custom calibrated and linearised over up to 9 points by using the T24 Toolkit. The T24-SAf has fixed factory calibration and cannot be linearised.
- Q: In the T24 transmitter range what is the difference between the 'i' and 'e' ?
-
A: The ‘i’ modules (T24-SAi, T24-SAfi, T24-VAi, T24-IAi) all feature an on chip
integrated antenna. The ‘e’ modules (T24-SAe, T24-SAfe, T24-VAe, T24-IAe) are
fitted with a miniature UFL connector which can be used with any of the antenna options available; the T24-ANTA (PCB antenna) or T24-ANTB (fixed 90 degree Whip antenna) or T24-ANTC (flexible whip antenna). - Q: How many transmitter modules can be acquired by the base stations?
-
A: Each base station can use one of 16 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: What are the input ranges of the T24 transmitter modules?
-
A: T24-SA 2.5mV/V calibrated strain gauge based measurement; T24-VA 0-10V, T24-IA 4-20mA, T24-TA pt100 sensor input, T24-RA potentiometer 500 to 100000 Ohms and T24-PA 0.5Hz to 3kHz.
