The Wtrans series contains a new transmitter with M12 connection for adaptation to existing Pt 1000 resistance thermometers. Additional receiver designs are also available with two rather than four analogue inputs, featuring two relays for a variety of monitoring tasks. The transmitters are located in a probe handle and are protected by a watertight housing. The radio frequencies used are largely non-sensitive to external disruptive influences and permit transfer even in a rough industrial environment. The probe with a fixed protective tube is designed as an insertion measurement probe and is available with an installation length of 50 to 1000mm. A platinum chip resistor is used as a high-precision measurement element. On the transmitter side, a functional temperature range of -30 - 260Â°C has been achieved with a fixed protective tube, and a functional temperature range of -100 - 500Â°C with M12 connector and remote probe.
