The PS-7000A pressure sensor is a fully submersible pressure measurement sensor designed by Greenspan for remote applications. It uses a sophisticated capacitive ceramic pressure-sensitive diaphragm. It has special features such as 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 PS-7000A has a standard, 2-wire, loop powered, 4-20mA output 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 other applications.
This manual provides guidance for configuring, operating, and maintaining the Greenspan PS-7000A pressure sensor, designed for remote applications with a ceramic capacitive transducer. It includes details on installation, calibration, environmental compatibility, and warranty conditions. The sensor is loop-powered with 4-20mA output and can be adjusted for fluid density and gravity. It is packaged in a stainless steel housing with a UV-stabilized cable suitable for harsh environments.
The sensor is fully submersible, corrosion-resistant, and offers high overload protection. It is calibrated and tested under ISO 9001 standards, with a certificate of conformance provided. Users are advised to check model and range before installation and to maintain documentation for reference and warranty claims.
