Flameproof Temperature Transmitter

TX1HM (Flameproof)

FTX1HM is a temperature transmitter housed in a heavy-duty enclosure certified flameproof for gas groups I, IIA & IIB with IP65 rating - completely dust proof and a good level of protection against water. FTX1HM is a head-mounted “all-in-one” 2-wire temperature transmitter. Its high reliability industrial design offers some rare functions, e.g. 4~20 mA or 20~4 mA selection. The flat design gives easy access to terminals and adjustments and a large central hole lets the lead wires or an insert tube pass easily. FTX1HM accepts input from Pt100 RTD sensors through a 3-wire connection and can be designed on request for other inputs such as Pt50, Pt200, Pt500 and Pt1000. Relieved of a display, this transmitter is a cost-effective option. 1 LED on the top of the unit indicates it is operating. It is accurate to 0.1% of span. FTX1HM is adjustable for 8 overlapping ranges in °C or °F and gives a temperature linear output. All selections are made by solder jumpers and it is calibrated via ‘Fine’ ZERO/SPAN potentiometers. The transmitter is powered by a 6.2 - 32 V DC loop supply. This product features Radix's proprietary sensor-break indication technology.
