With a Metal Connection Head

These resistance-type temperature sensors are intended for contact temperature measurement of gaseous substances. The standard temperature range in which the sensors can be utilised is -30 °C to 100 °C. The sensors can be utilised for any control systems that are compatible with sensing element output signals or output signals quoted in the table of sensing element types.

The temperature sensors are designed to be operated in a chemically non-aggressive environment.
