T24-TA - Wireless Telemetry Temperature Acquisition Module

The T24-TA temperature acquisition module is a high performance device designed for OEM integration for the collection and processing of temperature measurements. The wireless module requires an external platinum temperature sensor (Pt100 type 385).

Measuring temperature and periodically transmitting, between transmissions the device can be placed in a power saving sleep mode to conserve batteries. Miniature in size, the wireless temperature PCB transmits on license-free 2.4Ghz, avoiding local radio interference to ensure data integrity and security.

Although this module can be used ‘as is’ for OEM solutions there are a number of enclosure options available. The 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.

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.
