Submersible Hydrostatic Level Transmitter 4-20mA RS485 HART 24VDC with 0.5%FS Accuracy and 20mH2O Range
The Submersible Hydrostatic Level Transmitter is a precision instrument designed for accurate liquid level measurement in industrial applications. Utilizing a high-performance piezoresistive diffused silicon pressure sensor, it converts static pressure into standardized 4-20mA, RS485, or HART output signals with direct linear correlation to liquid depth.
- Compact design for direct submersion into liquids
- High accuracy measurement with 0.5%FS or 1%FS options
- Multiple output options: 4-20mA, RS485, HART protocol
- 24VDC power supply with 12-36V operating range
- On-site liquid level display capability
- Zero shift and full-scale span shift adjustments

Standard Open Container Installation: Position the transmitter vertically at the bottom of the container and secure the cable at the container's opening junction box.
High Viscosity Media: Use a casing or bracket for proper positioning in sewage tanks and similar applications.
Outdoor Installation: Place terminal box in well-ventilated, dry areas away from direct sunlight and rain to prevent overheating and water damage.
Flowing Water Applications: Insert a steel pipe (approx. 5cm diameter) with drilled holes opposite flow direction to allow water entry while securing cable at pipe outlet.
High Fluctuation/Sediment Conditions: Install damping devices to filter sediment and mitigate dynamic pressure effects for accurate measurements.
Ideal for liquid level measurement and control across multiple industries including petroleum refining, chemical processing, power generation plants, municipal water supply systems, and hydrological exploration projects.
