Main features

Just stick it on the object

This sensor can be sticked on the narrow space or on the small object for easy temperature measurement.
・Nonwoven glass fabric type (standard)
・Polyimide resin type (for use in clean room)

This is a type K thermocouple

With the dedicated cable with a connector (W-ST-50A), the sensor can be connected to the input terminal of the instrument configured for thermocouple input type K.
Wide selections of cable end types are offered. For example, Y-shaped crimp terminal or TC connector.

Excellent response

Since thermal capacity of the sensor itself is very small, temperature can be quickly measured. This makes the sensor suitable for collecting temperature profiles.

Easy to measure temperature with a cable clamp

Bare end type sensors (ST-50B / ST-51B / ST-51SB) are offered for temperature measurement of tiny objects.

Measures max.300°C temperature

Use of silicon adhesive enables adhesion on almost any objects except some hard-to-bond articles.
※ No Siloxane is generated.

Up to 150°C: Capable of repeated use by sticking/removing the sensor.
Up to 200°C: Capable of repeated use on condition that the temperature is not lowered below 150°C.
Up to 250°C: Capable of repeated use on condition that the temperature is not lowered below 200°C.
Above 250°C: Readhesion is not possible.
※The number of repeated use depends on the operating environment
