Thermocouple

Thermocouple is the description for electrical feedthroughs that are commonly used for temperature measurement systems. A thermocouple feedthrough does not measure temperature, but rather it is used to conduct the thermocouple’s voltage signal from inside the vacuum system to an external instrumentation device. MPF uses ceramic-to-metal sealing technology to braze various metals used in thermocouple assemblies to high purity alumina ceramic insulators. Thermocouple feedthroughs are suitable for ultra high vacuum applications.

MPF offers several mounting options for thermocouple feedthroughs: Weldable (W), Quick Flange (QF), and Conflat Flange (CF). Most designs are also configured for Baseplate and NPT style adapters. Custom adapters, plates and flange configurations are available by request.

Miniature & Screw Type Connectors

The most popular Thermocouple connections are miniature and screw type connections, which are commonly used in many thermocouple applications. MPF offers miniature connectors for C, E, J and K type thermocouples. R, S and T type thermocouples require a screw and nut connection.

MS Connectors

Industry standard threaded connectors are available E, J and K type thermocouples. MS Connectors provide high pin
density and convenient circular style connectors for the air side, which accommodate up to 10 pairs of thermocouple leads.

Thermocouple and Power Combination

Many applications involve power leads to drive a process and the need for process control information provided by thermocouples.

MPF offers several standard designs which combine thermocouple and power feedthroughs into a single assembly.
