Model SA877PVC — DynaProbe Sensor Housing for Valve Retraction Applications

Model SA 877PVC — DynaProbe^® Sensor Housing for Valve Retraction Applications

Specifications
Ordering Information

The Model SA877PVC is a sensor housing assembly designed for use with the replaceable Model ST877 and ST977 DynaProbe sensors. This housing is suited for the most severe chemical industry applications where metals cannot withstand the corrosive nature of the process and is intended for valve retraction service. The Coupler is constructed from chemically resistant Kynar (PVDF). PVC is the standard material of construction for all other parts of this assembly.

Insertion length is 7 inches. Viton O-ring seals are incorporated throughout this housing to prevent damage to the sensor and to retard process seepage during insertion and retraction procedures. The sheath is designed with blowout protection, should the compression fitting be loosened at the process operating pressure. The SA877PVC sensor housing is designed with replaceable components providing simple and economic servicing.

DynaProbe^® pH and ORP Sensors
Must be Ordered Separately

Select the DynaProbe^® sensor for pH or ORP (Redox) measurement which is compatible with the host pH/ORP instrument. A wide selection of DynaProbe^® sensors both with and without automatic temperature compensation are available for most makes and models of pH/ORP instruments. For factory assistance, call our Tech Services at 1-800-288-2833.

Preamplifiers are also Available!
Ordered Separately

Select the optional preamplifier module to provide the correct interface signal between the DynaProbe^® sensor in the Model SA877 housing and the host pH instrument. A wide selection of preamplifier modules both with and without junction boxes are available for most makes and models of pH instruments.
