The GREENSPAN PS1000 water level pressure sensor manual provides product overview, installation, wiring, software setup, and technical specifications.
The GREENSPAN PS1000 is a ceramic‑capacitive water level pressure sensor designed for harsh environments. It offers selectable measurement ranges, 4‑20 mA or 0‑2.5 VDC analog output, and optional SDI‑12 output via an adapter. The sensor housing is made of corrosion‑resistant polyoxymethylene resin, with optional stainless‑steel construction for high‑temperature and high‑pressure applications.
The manual covers product features, installation options (including protective port sleeves and 1/4" BSP fittings), wiring diagrams, software configuration using the PS7000UTILITY program, and detailed technical specifications such as accuracy, temperature stability, power requirements, and cable length options. This manual is written in Chinese.

It includes a fully sealed vent system (CVS) that isolates the vent tube from ambient moisture, preventing condensation inside the cable.
Standard ranges are 2.5, 5, 10, 20, 40, 75, and 100 m, with custom ranges available on request.
The sensor operates from a DC supply of 8 to 30 V, with reverse‑polarity and surge protection.
