Multipoint Thermocouple Assemblies

Specialist Multicore and Multipoint Thermocouple Probes

Our multicore industrial cable, specifically multipoint thermocouples, are primarily used for temperature profiling in furnaces, chemical reactors and process lines. Multipoint thermocouple assemblies, improve control of the reaction process when compared with single-point sensors.

Typical examples of main multipoint thermocouples are:

  • Profiling during reduction of organic acids by exothermal oxidation.
  • Distillation or fractioning in crude oil separation.

TRM multipoint thermocouple probes are versatile and robust with high reliability and life performance.

FMP Sensor (Fine Multipoint Sensor)

The FMP sensor is a multipoint sensor in which multiple Type K sheathed thermocouples are enclosed in a single protection tube. Using ultra-fine thermocouples, it is possible to measure 7 locations with a 1mm diameter protection tube.

This is useful when it is not possible to install multiple sensors, or when it is desirable to eliminate the environmental impact of the sensor itself.

Above: 5 measuring points Φ1mm        Below: 2 measuring points Φ0.6mm

Construction

The measurement point can be set arbitrarily by changing the insertion length of Type K-sheathed thermocouple.

  • Up to 20 points can be measured with one protection tube.
  • When the ultra-fine Type K sheathed thermocouple is used, a maximum of 7 points can be measured with a 1mm diameter protection tube.
  • The operating temperature is suitable for medium and high temperatures up to 600° C. (Protection tube can be processed according to the shape of the object to be measured)
  • Available materials are SUS-304, 316, 316L (Inconel and titanium are under development)

Applications

  • Temperature distribution measurement in various furnaces and chambers.
  • Internal Mold temperature distributions measurements.
  • Various liquid temperature distribution measurements.
  • Liquid level measurements (high temperature, low temperature).
