High Temperature Version
Ceramic Active Shield Insulator and Thermal Isolator
Provides a ceramic Active Shield insulator and a Thermal Isolator for when the process
temperature is greater than 200 E C / 392 E F and/or for when the product to be detected is very
abrasive. The high temperature version is rated for applications up to 400
E
C / 752

F.
The Thermal Isolator provides a separation distance between a high process temperature
inside the vessel and the electronic housing outside the vessel. This reduces the operating
temperature of the electronics to a value equal to or less than 85
