DESCRIPTION

The Myron L® Company CS951 and CS951LS Conductivity sensors are designed to operate in demanding environments. They are an excellent sensor for a wide variety of water quality applications.
Process connections are made via a 3/4” NPT fitting. This fitting may be installed into a line or tank, or may be reversed so that the sensor can be inserted into a standpipe for use in submersion applications1. The standard versions have a 316 stainless steel body and fittings made from temperature resistant and chemically non-reactive polypropylene. Optional fittings of stainless steel or PVDF (polyvinylidene difluoride) are available for even better chemical and temperature resistance.
All CS951 and CS951LS sensors are completely encapsulated and feature a dual O-ring seal design that ensures long life under demanding conditions. The outer O-ring bears the brunt of environmental attacks allowing the inner O-ring to maintain a reliable seal.

The built-in PT1000 RTD makes accurate and quick temperature measurements for superior temperature compensation2

Assembled CS951 Sensor

Standard cable length is 10ft. (3.05m) terminated with 5, tinned leads (4 signal; 1 shield; separate 5-pin terminal block included). They are also available with optional 25ft (7.6m) or 100ft (30.48m) cables.
