Description

The 803 / 803S Submersible Level Transmitter is a high-precision hydrostatic level measurement device designed for continuous liquid level monitoring in water tanks, reservoirs, wells, sewage systems, and industrial process applications. It utilizes a high-performance diffused silicon pressure sensing element to convert liquid level changes into a stable electrical output signal. The rugged stainless steel construction ensures reliable operation in harsh industrial environments.

The transmitter features a 304 stainless steel housing, a 316L stainless steel diaphragm, IP68 waterproof protection, and a double-shielded vented cable for excellent long-term stability and interference resistance. The specially designed pressure inlet structure helps reduce clogging and pressure impact, ensuring accurate and dependable level measurement.

The 803 model provides standard analog signal output for PLC, DCS, and control systems, while the 803S model integrates a local digital display, allowing users to monitor liquid level values directly on site for easier operation and maintenance.
