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.
