Description
The T24-VA 0-10Vdc wireless voltage transmitter module enables high accuracy wireless measurement of signals from voltage output sensors such as pressure transducers, LVDT displacement sensors, level/depth sensors and torque transducers.
Transmission ranges of up to 600 metres are possible using the internal antenna, while the use of an external antenna increases the wireless voltage transmitter operating range up to 800 metres.
The T24-VA requires a power supply of just 3Vdc to operate which is typically provided by 2x ‘AA’ batteries and provides a highly stable, high resolution signal that can be received by any of the T24 range of 2.4GHz telemetry instrumentation.
Output rates of up to 200 readings/second are possible at a noise-free resolution of 1 in 7000, increasing to 1 in 15,000 at a reduced output rate of 1 reading/second or less.
The compact T24-VA voltage input wireless telemetry acquisition module can be integrated into load cells and other sensors if sufficient space is available. Alternatively, it can be mounted into either the T24-ACM(2x ‘D’ size batteries) or T24-ACMi (2x ‘AA’ size batteries) battery-powered modules to complete your wireless sensor.
