Introduction
The T24-RA radio potentiometer acquisition module is a
high performance PCB designed for collection and
processing of related measurement. The module
measures the resistance and periodically transmits it.
Between transmissions the device is optionally placed
in a power saving sleep mode to conserve batteries.
Miniature in size, the PCB 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 100 or 200 meters which can
be extended with the use of high gain antenna’s and
repeaters.
The module’s 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.
Also available in IP rated enclosures.
See T24-ACM, T24-ACMi and T24-ACMm.
