The new stainless steel shield option is for the KPSI Series 750, a non-fouling, anti-clogging level transmitter designed for harsh sludge, slurry, and other water and wastewater applications. The new shield protects the unit's elastomeric diaphragm in these environment, increasing the life of the product.

The KSPI Series 750 level transmitter is made of type 316 stainless steel in a compact, rugged package. The transmitter has a 3-in. wide sensing area and a highly flexible, PTFE elastomeric diaphragm that is directly exposed to the sensing medium.

The 316 stainless steel shield protects the diaphragm from harmful elements that could jeopardize product performance, such as sharp object that may be protruding from the bottom of a wet well. The shield, which is factory installed by PSI, attaches directly to the bottom of the unit using a 1-in. standoff and a stainless steel plate. This configuration can also be used to provide spacing between the well floor and the PTFE diaphragm that it protects.

The transmitter has a pressure range of 0-5 to 0-300 psi and features state-of-the-art, surface-mount internal signal conditioning that provides a power supply rejection of 0.001 percent with a choice of either two-wire 4-20 mA or three-wire 0-5 Vdc outputs.
