Flameproof Temperature Transmitter

TX3DR (Flameproof)

TX3DR is a loop-powered isolated Temperature Transmitter housed in a heavy-duty aluminium alloy flameproof enclosure. The enclosure is certified for gas groups I, IIA & IIB (optionally for group IIC also) with IP65 rating - completely dust proof and a good level of protection against water. TX3DR receives input from 8 types of thermocouples (B, E, J, K, N, R, S, T); Pt100, Pt50 and Pt200 RTDs; and 4-20 mA and 0-50 mV linear input. Operators can calibrate ZERO and SPAN easily via membrane keys on the front of the temperature transmitter. TX3DR has a large 4-digit LED display on the front of the instrument to indicate the process value and facilitate programming. It is powered by a 11.5-32 V DC loop supply. TX3DR provides signal isolation between input and output of 1000 V AC RMS/1 minute and 250 V AC RMS/continuous. It’s output is selectable between 4-20 mA or 20-4mA. Programmable parameters on TX3DR include digital filter level, sensor break upscale and downscale limits, unit of measurement, output type and autoranging, which must be specified by the user before ordering. Radix also provides a flameproof version of this temperature transmitter which is certified for gas groups I, IIA and IIB
