Thank you for purchasing the Greenspan Pressure Sensor Model PS7000. This manual provides a guide to the
configuration, operation and maintenance of these sensors to provide long term reliable and accurate monitoring.
The Greenspan PS7000 is fully submersible Pressure Measurement Sensor designed for remote applications. It
utilises a sophisticated capacitive ceramic pressure sensitive diaphragm. Its special features include high overload
protection (up to 60 times nominal pressure) corrosion resistance and long term stability. The change in the
capacitive element varies with applied pressure. This variation is measured by an electronic circuit and converted
into an analogue output. The sensor can be supplied in a variety of standard ranges.
The PS7000 has a standard, 2-wire, loop powered, 4-20mAoutput with an option for 0-2.5Vdc suitable for a wide
range of Data Loggers, Process Controllers and other third party devices. New features include the ability to re-
range the sensor as well as adjust the fluid density and gravity to suit specific applications.
The instrument is packaged in a small, robust, stainless steel housing fully sealed against moisture penetration and
is hardwired to either vented or non-vented cable supplied by Greenspan.
The sensors are suitable for applications in harsh remote applications including groundwater, streams and rivers,
water storage bodies including stratification studies, hydrological run off studies and industrial process
monitoring.
Along with this manual, there are several other documents that may assist in the successful configuration and
operation of the Greenspan PS7000 Sensor. These should be maintained on file as a permanent reference as to
the features, applications and use of the PS7000.
