4.2.3 Insulation
Siemens always recommends insulation of the sensor in both the compact and the remote
versions. This recommendation applies to both battery-powered and mains-powered versions.
The insulation will prevent heat transfer to the transmitter (compact versions) or terminal box
(remote versions).
For media temperatures above 120 °C (248 °F) only remote installation is allowed.
