Typical applications include:    Refrigeration

The 85-Series has features that make it suitable for use in a wide variety of applications. High vibration and shock, electrical noise, and temperature extremes, all of which the 85-Series can handle, characterize many of these applications.


The 85-Series wetted parts are made of 17-4PH Stainless Steel which promotes long life and resistance to media corrosion. This high strength stainless steel construction also promotes good over  range and burst protection.

The 85-Series electrical components are protected by a rugged stainless steel housing which is small and lightweight for optimum compatibility with system designs.

As a totally self contained electronic package, the 85-Series poly silicon sensing element coupled with a high level output ASIC circuitry assures excellent accuracy and long term stability.
