Allied Tools Corporation’s ultra-miniature Temperature Transmitter converts mill volt input from thermocouples or resistance from RTD or potentiometer into 4 to 20 mA output. Featuring state-of-the-art integrated circuits and electronic design, these ultra-compact transmitters have a diameter of only 45mm and are designed to fit inside many compact thermo well protection heads. Transmitters can eliminate long runs of costly field wiring in a variety of applications. A stable 4 to 20 mA output signal is produced proportional to the transmitter’s specific input type and calibrated temperature range. Adjustability of zero and span is provided to facilitate some range ability. The transmitted signal eliminates noise pickup, voltage drops, and multiple cold junction errors, and it requires only a twisted pair of copper wires for loop connections. All models and ranges of these ultra-miniature transmitters are available with fully epoxy-potted electronics, which gives ultimate protection in extreme environments.
