Introduction to Depth Sensors
Yushan Sensing is a brand new depth sensor, a fully sealed immersion liquid level measuring instrument. This type of product consists of a long-term stable and reliable diffusion silicon pressure sensor, a high-precision dedicated circuit, and a 316L stainless steel housing. The integrated structure and standardized signals provide convenience for on-site use and automated control. The dedicated cable is sealed and connected to the casing, and can be used in liquids compatible with the transmitter structure material for a long time.
The product has better repeatability and stability, is sturdy and durable, and has high economy. It is suitable for water level measurement of Rivers and Lakes, liquid level measurement of containers and storage systems, liquid level monitoring of fire pool and water tank, water level monitoring of rainwater and sewage lift pump and pumping station, and water level monitoring of inspection wells.
Sensor features:
Digital sensor, RS-485 output, supporting MODBUS, capable of online continuous monitoring, real-time control of water quality dynamics;
Input based measurement method;
All stainless steel structure design, small size, light weight.
