Description

The Industrial Submersible Liquid Level Transmitter is a high-precision pressure sensing solution engineered for continuous monitoring of water and other non-corrosive liquids. By measuring the hydrostatic pressure at the bottom of a container, it provides a stable and linear signal proportional to the fluid depth. This sensor is available in two professional output configurations: a 0.5 - 4.5V voltage version for easy integration with standard microcontrollers and a 4 - 20mA current loop version for long-distance, interference-free industrial deployments.

Advanced Sensing & Signal Stability

Industrial Grade Durability Constructed with 304 stainless steel and a fully sealed IP68 structure to resist moisture, corrosion, and pressure in deep-water environments.

Versatile Output Integration Choose between the high-sensitivity 4-20mA signal for remote PLC monitoring or the 0.5-4.5V output for direct analog-to-digital conversion.

Industrial Monitoring Scenarios

• Reservoir & Tank Monitoring: Accurate tracking of water levels in fire tanks, reservoirs, and industrial storage.

• Wastewater Treatment: Reliable level sensing for sumps and non-corrosive wastewater management systems.

• Smart Agriculture: Monitor irrigation pond levels and deep-well water availability for automated pumping control.
