Magnetostrictive and Magnetic Displacement Sensor
Product Name:MR Soft Cable Magnetic Liquid Level Meter
Product Summary:
Product Summary:
MR is a flexible soft cable magnetostrictive liquid level sensor with voltage, current and RS485 signal output. The built-in imported waveguide wire is used as a measuring unit, which is processed by DSP digital signal, with high precision, no temperature drift, no contact, and a life span of up to 20 years; the flexible cable is resistant to high temperature, pressure and corrosion, and the float pressure is 1.5MPa, which can be applied in most liquid level measurement applications. ★ The range can be 12 meters.
Especially suitable for long stroke displacement or liquid level measurement
