The T24-RA Wireless Telemetry Potentiometer Acquisition module is a high performance wireless device designed for the collection and processing of resistance related measurements. The T24-RA measures resistance and periodically transmits it.
Low power modes allow the T24-RA wireless current sensor acquisition 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 module can be configured to last several years on 2 x alkaline AA batteries or alternatively powered from 2 x NiMH or 1 x 3V Lithium.
The high accuracy, low noise measurement electronics in the T24-RA 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 wirelessly to other T24 devices such as handheld displays, analog outputs and base stations etc.
Although the T24-RA modelo can be used ‘as is’ for OEM solutions there are a number of enclosure options available.
Integral antenna option offers up to 800m (2600 ft) range and external antenna options allows up to 800m (2600 ft) range in an open field site.
The licence free 2.4 GHz direct sequence spread spectrum (DSSS) radio telemetry 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.
