Faults - WIKA TR10-0 Mode D'emploi

7. Safety-related instructions / 8. Faults
Temperature class classification, ambient temperatures
A heating in the connection head can occur with built-in transmitter through faulty
electronics. The permissible ambient temperatures depend on the cases used and any
EN
additionally fitted 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 case is less than 25 K
if the following conditions are observed: supply voltage U
transmitter is operated in a current limit of 22.5 mA.
The temperature class is dependent upon the user application and the ambient temperature.
The permissible ambient temperatures for third-party products can be seen from the relevant
approvals and/or data sheets. However, an impermissible heat reflux from the process
which can exceed the operating temperature of the case or the temperature class, must be
prevented through suitable heat insulation or a suitably long neck tube.
