The
KPSI
®
500 Series
and
KPSI
®
350 Series
SDI-12 submersible pressure transducers use an
isolated diaphragm sensor that is specifically designed for use with hostile fluids and gases.
The sensor uses a silicon pressure cell that has been fitted into a stainless steel or titanium
package with an integral, compliant stainless steel or titanium barrier diaphragm.
Different user-installable nose caps are available for the
KPSI 500 Series
transducer. The
closed-face end cap with #8-32UNC-2B threaded hole is best used where weights are required
and for those installations where users may encounter sharp, protruding objects. The open-face
end cap that allows maximum contact with the liquid media is ideal for wastewater and “greasy”
applications where clogging of the sensor is a concern. A high density “piezometer” screen may
be inserted into specially-drilled open-face end caps should the user decide to completely cover
the
KPSI
500 Series
transducer with soil or silt.
