T24 Wireless Transmitter modules connect directly to a Strainsert sensor. They provide strain excitation, signal measurement, ADC conversion, and transmission of reading data to a T24 Wireless Receiver.

• Wireless range up to 800 m (2,600 ft).
• Internal batteries (2 D Cells) or external power.
• 164 mm (6.5 in) x 84 mm (3.3 in) x 57 mm (2.2 in).
• Environmentally Rated, IP 67.
