Model SA878 — DynaProbe Sensor Housing for Insertion Applications

Specifications
Ordering Information

The Model SA878 is a sensor housing assembly designed for use with the replaceable Model ST877 or Model ST977 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). All other parts of this assembly are 316SS. Optional Hastelloy C and Titanium versions are also 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 blowout protection while operating under pressure. The SA878 sensor housing is designed with replaceable components providing simple and economic servicing. A completely illustrated instruction manual is supplied with each Model SA878.
