ESL040 Submersible Level Transmitter
ESL040 Submersible Level Transmitter adopts silicone piezoresistive sensing technology, converts pressure into electrical signal, and converts into standard current, voltage and RS485 & I2C signals and outputs.
By temperature compensation and linear calibration, durable 316L stainless steel construction and silicone oil-filled method, ESL040 submersible level transmitter is well known for its superior reliability, reasonable cost, and ready availability. It can be directly connected with PLC/DCS, with display instrument and computer, the remote signal transmission also can be carried out.
ESL040 submersible level transmitter features small size and integral signal conditioning; it can be easily installed at plant to measure water, or oil-filed to measure petroleum, or anywhere quality liquid level sensors are needed.
ESL040 submersible level transmitter is widely used in liquids measurement of petrochemical, water supply and drainage, environmental protection, and electric power.
