Model SA858 — DynaProbe Sensor Housing for Insertion Applications

Specifications
Ordering Information

The Model SA858 is a sensor housing assembly designed for use with the replaceable Model ST857 DynaProbe® sensors. This time-proven insertion housing is suited for the most severe process industry applications. The Coupler is constructed from chemically resistant Kynar (PVDF). 316 SS is the standard material of construction for all other parts of this assembly. Optional Hastelloy C and Titanium versions are available.

An assortment of insertion lengths are available from 2 inches to 27 inches. Viton O-ring seals are incorporated throughout this housing to prevent damage to the sensor and to prevent process seepage during normal operation. The sheath is designed with blow-out protection while operating under pressure. The SA858 sensor housing is designed with replaceable components providing simple and economic servicing. A completely illustrated instruction manual is supplied with each Model SA858.
