Temperature class classication, ambient temperatures

A heating in the connection head can occur with built-in transmitter through faulty

electronics. The permissible ambient temperatures depend on the housings used and any

additionally-tted head-mounted transmitter.

For all WIKA connection heads with built-in WIKA temperature transmitters, the

following interrelation is valid:

The temperature increase on the surface of the connection head or housing is less than

25 K if the following conditions are observed: power supply U

maximum DC 30 V when the

transmitter is operated in a current limit of 22.5 mA.

This yields the following temperature class classication:

Atmosphere Temperature class Limits for ambient temperature

Gas atmosphere T6 -50 ... +60 °C

T5 -50 ... +75 °C

T4 -50 ... +85 °C

Dust atmosphere T85 °C -50 ... +60 °C

The temperature class is dependent upon the user application and the ambient temperature.
