Thermo-Electra LEX55 Ex ec certified RTD sensor for zone 2 and 22 with transmitter

Product Code: LEX 55

Manufacturer: Thermo-Electra


Thermo-Electra manufactures ATEX and IECEx-certified RTD sensors for hazardous areas. Both single and multipoint for zone 0, 1, 2 and 21, 22 with Exi, Exe, Exd, Ext, Exce (Exna) approvals. Our precision Pt100 and Pt1000 wire-wound detectors are made to conform EN6071 standards. Ceramic or glass encapsulated and thin film detectors are used for our resistance thermometers. Next to that, a complete range of sensors with standard “DIN” constructions are developed with an interchangeable insert which allows for easy replacement and can be equipped with a built-in two-wire 4-20mA transmitter. Also, able to be fitted with an integral head mount transmitter.
