Pressure Type Liquid Level Sensor
It is suitable for liquid level measurement of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries. The exquisite structure, simple adjustment and flexible installation provide convenience for users to use easily. Standard signal output modes such as 4 ~ 20mA, 0 ~ 5V and 0 ~ 10mA are optional by the user according to needs. Using the principle of hydrostatics to measure liquid level is an important application of pressure sensor. The special cable with ventilation duct in the middle and special sealing technology are adopted, which not only ensures the water tightness of the sensor, but also connects the reference pressure chamber with the ambient pressure, so as to ensure the high precision and high stability of the measurement.
