T24-SA Wireless Telemetry Strain Gauge Acquisition Module Features Miniature Acquisition Module for Wireless Strain Gauge Measurement Exceptionally low power for long battery life Transmits on license free 2.4GHz Remote ‘on’ and ‘off’ to preserve battery life 120m (400 feet) range Simple Configuration and Calibration via PC using Toolkit Software (included in price) Calibratable to provide any standard engineering unit output for given input Introduction Forming the core of the T24 range, the T24-SA strain gauge acquisition module is a high performance PCB board designed to be embedded alongside load cells or other strain input sensors to provide wireless strain gauge measurement. Options also available for wireless current (4-20mA) and voltage (0-10V) acquisition (T24IA & T24-VA). Miniature in size, the device transmits on license-free 2.4Ghz, avoiding local radio interference to ensure data integrity and security. Data is provided in real time at variable speeds with a direct line of sight range of 120 meters (400 feet) which can be extended with the use of antenna’s and passive repeaters. The devices transmit to a range of receivers including handheld indicators, digital displays, analogue and serial outputs, PC display and wireless printer (please see separate sheets) and has various powering options. Antenna options available to extend range. Also 2KHz fast version for high speed applications.
