Greenspan PS1000 Pressure Sensor- Superceded

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The Enhanced features and performance of the new PS1000 pressure sensor provides users with an affordable solution to a wide range of water level and pressure monitoring applications. The PS1000 has a standard, 2 wire, loop powered 4-20mA output with an option for 0-2.5Vdc. New features include the ability to re-range the sensor, as well as adjust the fluid density and gravity to suit specific applications.

The PS1000 has a 0.1% FS Accuracy with a standard output of 4-20mA (0-2.5Vdc as an option)

Superceded by PS1000A


o Can be installed in active waters (acidic or salty) that would damage a stainless steel sensor.
o No need for regular desiccant replacement resulting in fewer field visits
o Low cost of ownership and minimal maintenance
o Ease of use and long term reliability

The Sensor is ideal for use in groundwater, surface water and wide range of water monitoring and environmental projects. A durable corrosion resistant body, rugged ceramic capacitance transducer and double O ring sealing ensure suitability for harsh environment applications. The sensor comes fitted with a moulded polyurethane cable as standard. Other cable options are also supported.

• Loop powered - Battery or Solar
• 4-20mA or 0-2.5Vdc outputs
• 0.1% FS accuracy
• Field re-ranging and calibration
• User inputs for fluid density and Local gravity
• Double O-ring Design and moulded cable gland
• Acetyl construction
• ½” diameter ceramic capacitance transducer
• Long-term stability better than 0.2% per annum
• Optional SDI-12 adaptor for serial output
• Threaded fitting for Process connection.

An optional SDI-12 adapter can provide a serial output for external controllers or data loggers.

• Sewer wet well
• Borehole monitoring
• River and dam Level monitoring
• Floor warning Systems
• Tank level monitoring
• Process level and pressure monitoring.

The Sensor can be supplied in various gauge (vented) or absolute (non vented) pressure ranges. Gauge sensors utilise a closed vent system (CVS). This provides barometric pressure venting of the sensor, without the need to continually replace desiccant.
