The PS3100 water pressure sensor from Grunman uses a durable ceramic capacitive sensor to provide better linear data transmission and accuracy, with a variety of standard measurement ranges to choose from. It has 2MB internal memory, is battery-powered, and can be used independently in remote areas or connected to a wireless transmission. 36-point linear and temperature calibration ensures stability, repeatability and accuracy of pressure and temperature readings throughout the range.
The Greenspan PS3100 water level pressure sensor uses a robust ceramic capacitive element to deliver high linearity and temperature‑compensated measurements across multiple selectable ranges. It is housed in a corrosion‑resistant phenolic resin case with optional stainless‑steel construction for harsh environments.
The guide details sensor installation, wiring options (RS232 or SDI‑12 via adapter), software configuration with SmartCom, and provides full technical specifications such as measurement ranges, accuracy, power consumption and memory capacity. This manual is written in Chinese.
| Standard measurement range | 2.5–100 m |
|---|---|
| Gauge pressure range | 20–100 m |
| Working temperature (with compensation) | 0 °C to 50 °C |
| Overall accuracy (full scale, 25 °C) | ±0.1 % FS |
| Memory capacity | 2 Mb (≈250 000 readings) |
| Power supply | 8 V – 30 V DC |
| Current consumption (operating) | 20 mA (sleep <0.2 mA, communication 30 mA) |
| Signal output | RS232 or SDI‑12 (adapter required for SDI‑12) |
The sensor can output data via RS232 directly or via SDI‑12 when an SDI‑12 adapter (model 7SDI‑1000) is installed.
It has 2 Mb of memory, capable of storing about 250 000 readings when sampled every five minutes.
The overall accuracy is ±0.1 % of full scale at 25 °C.
