The OPTITEMP TCA-M70 is a mineral insulated (MI) cable thermocouple equipped with a compensation cable. It comes with an optional thermo plug or free insulated flying wires for installation where connection terminals already exist. The MI cable sensor is particularly suitable for applications where the ambient temperature exceeds the maximum allowable temperature of standard cable material (e.g. in test bench applications). The MI cable of the sensor can be easily formed to fit into limited spaces. Its small diameter makes it perfect to provide fast response times.
The OPTITEMP TCA-M70 is mechanically and thermally highly stable. It is available with thermocouple type J, K or N, single (standard) or double (optional), according to IEC 60584 class 1. The measuring point can be ordered as isolated (standard) or grounded (optional). The MI thermocouple sensor is best used for measuring high process temperatures of gases and liquids (up to +1250°C / +2282°F), at low to medium pressures and flow velocities.
