Product introduction Based on the principle that the measured liquid static pressure is proportional to the height of the liquid, the input type static pressure liquid level transmitter adopts the piezoresistive effect of the foreign advanced isolated diffused silicon sensing element to convert the static pressure into electrical signal, and then through temperature compensation and linear correction, it is converted into standard electrical signal (generally 4 ~ 20mA). KL series static pressure liquid level transmitter is suitable for liquid level measurement of various media in petrochemical, metallurgical, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries. Exquisite structure, simple adjustment and flexible installation mode provide convenience for users to use easily. 4 ~ 20mA, 0 ~ 5V, 0 ~ 10mA, RS485 and other standard signal output modes are optional by users according to their needs. | ||||||||
