Description
The T24-PA wireless pulse transmitter module enables high accuracy wireless measurement of signals from any sensor or measurement device with a pulsed output such as an optical or hall effect type RPM sensor.
Transmission ranges of up to 600 metres are possible using the internal antenna, while the use of an external antenna increases transmission range up to 800 metres.
The T24-PA wireless pulse transmitter module 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 with a resolution of up to 0.25µsec.
The compact T24-PA wireless pulse transmitter module can be integrated into your sensor if sufficient space is available. Alternatively, it can be mounted into either the T24-ACM (2x ‘D’ size batteries), T24-ACMi (2x ‘AA’ size batteries) or miniature T24-ACMm battery-powered modules to complete your wireless sensor.
