Description

The RS-PM200 series operates on the hydrostatic pressure principle (P=ρgH), where the static pressure exerted by a liquid column is converted into an electrical signal via an internal, protected diaphragm. The sensor’s front-end protective cap and sloped liquid guide hole shield the sensitive element from direct impact and prevent silt or impurities from clogging the system.

Engineered for harsh environments, the unit features a sealed, anti-condensation internal design and a high-quality air-conducting cable rated for permanent submersion. Its built-in micro-signal processing circuit provides remote transmission capability with reverse polarity and EMI protection, making it suitable for integration into industrial SCADA, PLC, or data acquisition systems.

Key Features

Industrial-grade stainless steel construction with IP68 waterproof rating for permanent submersion.
Integrated RS485 Modbus output for robust, noise-immune long-distance communication.
Advanced automatic temperature compensation and correction algorithm for high accuracy across operating range.
Superior long-term stability (±0.1%FS per year) and minimal thermal drift (±0.02%FS/°C).
Built-in protection against reverse polarity, overcurrent, overvoltage, and electromagnetic interference (EMI).
Sloped liquid guide hole design prevents sediment buildup and mitigates the effects of water surface turbulence.
Rated for media temperatures from -10°C to +85°C, with compensated operation from -20°C to +85°C.
Withstands overload pressures up to 200% of full scale for enhanced durability.

Applications

Continuous level monitoring in deep water wells, geothermal wells, and boreholes.
Reservoir, river, and ocean water level measurement for hydrological studies.
Industrial tank and process vessel level control in water treatment and chemical plants.
Municipal water supply and sewage treatment plant monitoring and automation.
Subsurface fuel/oil storage tank inventory management and leak detection.

Frequently Asked Questions

What is the maximum depth this water level sensor can measure?

This specific RS-PM200-10-N01-A05 model is configured for a 0 to 10 meter water column measurement range. The sensor operates on hydrostatic pressure, and its 200% FS overload rating provides a safety margin. For applications beyond 10 meters, other range variants (e.g., 20m, 50m) within the PM200 series are available.

How do I communicate with this RS485 sensor?

The sensor outputs data via an RS485 interface, typically using the Modbus RTU protocol. You will need an RS485-to-USB converter or a PLC/controller with an RS485 port. Connect the sensor's two-wire RS485 bus (A/B lines) following standard polarity, ensure proper termination for long cable runs, and use Modbus register maps from the datasheet to read level, temperature, and diagnostic data.

Can this sensor be used in saltwater or corrosive liquids?

Yes, the stainless steel housing and IP68 rating provide excellent corrosion resistance, making it suitable for saltwater, treated sewage, and many industrial chemicals. For long-term submersion in highly corrosive media, verify the specific stainless steel grade (e.g., 316) compatibility with your application, as prolonged exposure to certain acids or chlorides may require additional protection.

What is the required power supply for the RS-PM200 sensor?

The sensor module typically operates on a standard DC voltage range, such as 9-28V DC, which powers both the sensing element and the RS485 transceiver. The included 10-meter cable carries both power and data. Always refer to the official datasheet for the exact voltage and current requirements to ensure stable operation and avoid damaging the internal protection circuits.

How do I mount and install this submersible level sensor?

Installation is straightforward: lower the sensor to the desired depth in your well, tank, or body of water, ensuring it remains vertical. Secure the cable at the top to prevent strain. The sensor is designed for full submersion, and the sloped guide hole should remain unobstructed. For applications with significant turbulence, consider using a stilling well or protective cage to minimize signal fluctuation from surface waves.
