Wireless Telemetry Pulse Acquisition Module (T24-PA)

The high performance T24-PA pulse acquisition device is specifically for the collection and processing of pulse related measurements. To provide wireless outputs in rpm, Hz and time as well as actual pulse counting and measuring the period between pulses.

Ensuring data integrity and security and avoiding local radio interference, the mini PCB module uses on license-free 2.4Ghz.

Data is provided in real time at variable speeds with a direct line of sight range of up to 200 meters which can be extended with the use of high gain antenna’s and repeaters, view our range of antennas here.

The module transmits to a range of receivers including handheld indicators, digital displays, analogue and serial outputs, PC display and wireless printer and has various powering options
Also available in IP rated enclosures.
See T24-ACM-PA, T24-ACMi-PA and T24-ACMm-PA
