Feature
Operating principle
The addition of a magnetic field to the magnetostrictive wire, the pulse signal is generated in the axial direction of the magnetostrictive wire, a magnetostrictive sensors are propagated as ultrasonic vibration.
When the ultrasonic vibration has reached the position of the float magnet coil is wound receive the magnetostrictive wire, the entire length, a pulse voltage is generated from the receive coil.
Converted to an analog signal the time to receive the detection signal from the signal generator coil magnetostrictive wire.
To achieve three things by a description of the operation of the above-mentioned principle.
- Compared to conventional resistance type to improve the measurement accuracy of about 1/50 to 1/100, high-precision detection is a major feature.
- Compared to conventional resistance type, can be provided at low cost of 1 / 2-2 / 3.
We offer two types of protection to the structure of the detector box.
- N：IP64（Drip-proof type）
- R：ExdIIB+H2T6（Flameproof）・・・You can use up to a hydrogen atmosphere.
