PS-1000L Water Level Pressure Sensor
The PS-1000L is a logging water level pressure sensor that has been manufactured in Australia for over 20 years.
The Greenspan PS-1000L is a fully submersible pressure measurement sensor, designed for remote applications. It utilises a sophisticated capacitive ceramic pressure-sensitive diaphragm. The PS-1000L’s body is made from robust Acetal and is fully sealed against moisture penetration. Furthermore, the body is hardwired to the cable supplied.
Its special features include high overload protection (up to 60 times nominal pressure) corrosion resistance and long-term stability. An electronic circuit measures the variation and converts it to an analogue output. A variety of ranges are available.
