Main features

Capable of measuring temperature of small objects

Use of thermocouple with a small diameter enables temperature measurement of small objects with small thermal capacity and surface temperature of a small object.

 

※Please use ceramic / epoxy bond or heat-resistant adhesive tape to stick the sensor tip on the measuring part.

This is a type K thermocouple

The sensor can be connected to the instrument configured for thermocouple input type K.  

 

The ceramic coat type is capable of measuring up to 500°C. (Up to 260°C for the fluorocarbon resin type)

Enables manufacturing a longer sensor.

ST-56:

The length between the thermocouple and the terminal can be specified from 200mm in increments of 100mm.

ST-55:

Cable joint is added to the ST-56.

Use of a larger element size in the cable joint enables manufacturing a longer sensor.

The thermocouple can be specified from 50mm in increments of 50mm and the cable joint section can be specified from 200mm in increments of 50mm.

※The length between the thermocouple and the cable joint section can be made to the desired length, but please specify the size so that the element resistance value is lower than 100Ω.
