Wireless Strain Gauge / Load Cell Acquisition (T24-SA)

Wireless Strain Gauge / Load Cell Acquisition (T24-SA)

This remote load cell acquisition module provides measurement system for strain gauge, pressure, load cell, linear displacement and other 4 wire bridge sensors. Providing direct mV/V input and 5V bridge excitation for up to 4 load cells. The miniature T24-SA size allows for the option of embedding within the sensor housing.

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 a base station. The wireless strain gauge sensor can be configured to last several years on 2 x alkaline AA batteries or alternatively be powered from 2 x NiMH or 1 x 3V Lithium.

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 up to 200 per second to other T24 devices such as handheld displays, analog outputs and base stations etc.

Although the T24-SA can be used as an OEM solution (for example creating a wireless load cell by embedding the module), there are enclosure options available (see T24-ACM in ‘Related Products Tab’).

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

The T24-SA’s integral antenna option offers up to 100m (325 ft) range and external antenna options allows up to 200m (650 ft) range in an open field site.

The licence 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
