PS7000 Pressure Sensor

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 PS7000 pressure sensor provides users with an affordable solution to a wide range of water level and pressure monitoring applications. The PS7000 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

Our new PS7000 sensor is easy to install and provides users with a rugged and reliable solution to long term unattended monitoring.

The enhanced features and performance of the new PS7000 pressure sensor provides users with an affordable solution to a range of water level monitoring applications. The linearity, accuracy and performance of this sensor is comparable to that of more expensive models.

Features:
• Suitable for use in 1” bore holes
• 4-20mA or 0-2.5Vdc outputs
• 0.1% FS accuracy
• Field re-ranging
• “True Level” user inputs for fluid density and local gravity
• Double O-ring design and moulded cable gland
• ¼” BSP fitting for process applications
• Passivated 316L Stainless Steel construction
• ½” diameter ceramic capacitance transducer
• Easy to install
• Low cost
• Long term stability better that 0.2% per annum
• Comes with standard 10m cable

The PS7000 new features include the ability for the user to re-range the sensor with simple to use, field adjust software. This interface also allows the user to enter “True Level” inputs for fluid density and local gravity.

Applications:
• Sewer wet wells
• Bore hole monitoring
• River and dam level monitoring
• Flood warning systems
• Tank level monitoring
• Process level and pressure monitoring

The Sensor is ideal for use in groundwater, surface water and a 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. An optional SDI-1X adapter can provide a serial output for external controllers or data loggers.

The PS7000 has a 0.1% FS Accuracy with a standard output of 4-20mA (0-2.5Vdc as an option). The sensor can be supplied in various gauge (vented) or absolute (non vented) pressure ranges.

Gauge Transducer Ranges 2.5m, 5m, 10m, 20m, 40m, 75m, 100m
Note: 10m = Approximately 1 BAR
Absolute Transducer Ranges 20m, 40m, 75m, 100m

Gauge sensors utilise a closed vent system (CVS). This provides barometric pressure venting of the sensor, without the need to continually replace desiccant.
Sensor Output 4-20mA, or optional 0-2.5V dc (SDI12 via adaptor)
Overall accuracy (combined linearity, hysteresis and repeatability) +/- 0.1% full Scale
Long-term stability 0.2%full scale per annum
