Magnetostrictive liquid level sensor is a new generation of high-precision liquid level measurement sensor independently developed using the principle of magnetostriction and advanced digital and analog circuits. Due to the use of non-contact measurement methods, the product has a long service life and strong environmental adaptability; No need for regular calibration and maintenance; The product has an absolute output, and there is no need to reset it to zero when restarting; And it has the technical characteristics of high precision, high stability, high reliability, and high repeatability; Supports multiple output modes such as current, voltage, Modbus, SSI, etc; It can achieve simultaneous measurement of liquid level and interface. Widely used in liquid level measurement and control in industries such as petroleum, chemical, water conservancy, environmental protection, pharmaceuticals, and beverages.
Reliable structure: IP68 rating, Exd II CT6 Explosion proof Certification
Anti corrosion design, suitable for corrosive environments
Can simultaneously measure interface and liquid level
