The OPTITEMP TRA-W90 is a plug-in cable sensor (RTD) made of a flexible mineral insulated (MI) cable that can be easily cut and formed to fit into limited spaces. The cable sensor is particularly suitable for temperature measurement in applications where the ambient temperature exceeds the maximum allowable temperature of standard cable material. The OPTITEMP TRA-W-90 is available with PVC, silicone or PTFE connecting cable. It can be provided with free insulated flying wires for installation in applications where connection terminals already exist.
