Radio Telemetry Module for Strain Gauge, 0-20mA, 0-10V Sensors


The smallest of our T24 radio telemetry modules provide high performance telemetry measurement electronics for strain gauge, pressure, load cell, linear displacement and other 4 wire bridge sensors. Available as 0-10V voltage input or 0-20mA current input and now available with pulse, potentiometer or temperature inputs – see order Information above.

The standard internal antenna supplied offers up to 100m (325 ft) range in an open field site. Low power modes allow the module to ‘power down’ between transmissions or to ‘power off’ completely and can be controlled by other T24 products such as the handheld displays or base stations.

An optional battery pack can be chosen to power the T24-ACMm which uses 2 x AAA cells and can be connected via simple 2 part screw field terminals. Also offers the option to fit wired completion resistors allowing a strain input to be either full, half or quarter bridge input.

The high accuracy, low noise measurement electronics deliver high resolution, low drift results which can be user calibrated over 9 points to enable linearization and to deliver results in user definable engineering units. The results can be transmitted at rates of up to 200 per second to other T24 devices such as the handheld displays, analogue outputs and base stations etc.

The module is configured and calibrated (either by applying known inputs or by table entry) using T24 Toolkit software which runs on a PC connected to a T24 base station.

The license free 2.4GHz 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.

The T24-ACMm-SA strain version provides direct mV/V input and 5V bridge excitation for up to 4 load cells.
