Product Description

1. Description

JW-LM02X(JY07) IP68 submersible level transmitter for sewage and sludge applications, featuring ceramic diaphragm, 4 to 20mA output, 8 to 30VDC power supply, 304SS housing and 1 meter PU cable for reliable wastewater level measurement.

2. Product Overview

JW-LM02X(JY07) The sewage sludge submersible level transmitter is designed for liquid level measurement in wastewater, sludge and other demanding water monitoring environments. Based on the principle that liquid static pressure is proportional to liquid height, the transmitter converts hydrostatic pressure into an electrical signal and outputs a standard industrial signal for monitoring and control systems.

The sensor uses a ceramic pressure-sensitive diaphragm with strong corrosion resistance. Combined with a dedicated digital circuit, the transmitter provides signal amplification, linear compensation, anti-interference processing and surge protection. With an IP68 structure and direct cable outlet, it is suitable for long-term submerged installation in sewage tanks, wastewater treatment basins, deep wells, reservoirs, flood control systems and irrigation projects.
