Product Description

LM06X series submersible temperature and liquid level transmitter is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It adopts the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert static pressure into electrical signals. The built-in PT100 temperature sensor can measure the liquid temperature simultaneously. Cooperating with a dedicated digital circuit, after signal processing such as signal amplification, linear compensation, anti-interference, and surge protection, it is made into an integrated product that can measure both liquid level and temperature.

Product Application

◆Groundwater, geothermal wells
◆Agricultural irrigation
◆Meteorological detection, disaster prevention systems
◆Liquid level and temperature measurement and control
