Linear Position/Displacement Sensor-Position Measurement

Introduction

The magnetostrictive linear displacement sensor, base on the magnetostrictive position sensing principle, contactless operation ensures linear sensors long service life, better adaptability to industrial environment; The position sensor has absolute output, and restart don't need from zero; The linear position sensor has high accuracy, high stability, the best durability and repeatability. Variety of output signals which include the current, voltage, SSI, Modbus, Profibus etc., and the linear sensors can meet any industrial applications such as petroleum, chemical industry, steel and iron, port, machinery, food and so on. The magnetostrictive linear position sensor is the best choice for high accuracy displacement control.

Magnetostrictive linear position sensor/displacement transducer features:
High accuracy
Durability, pass IP67 Explosion authentication
Simple adjustment and observation with debug software, LED detecting
Variety of output signals: Current, voltage, SSI, Profibus
Easy installation, screw thread or flange
Contactless operation

Magnetostrictive linear position sensor/displacement transducer applications:
Metallurgical industry: Hard mould casting, extrusion forming, cutting
Plastics industry: Injection, blown film, die casting
Construction: Tunnel drilling, bulldozer, excavators

Magnetostrictive linear position sensor/displacement transducer installation:
1) Stuck the linear position sensors by sensor holder, then fixed the holder in the sensor with lock nut.
2) Fixed Captive-sliding magnet on the holder through two Retainer washer # 6
And two Screws M3 x16, installation it on length rod; The captive-sliding magnet and rod should concentric as far as possible, but slightly eccentric will not affected sensor performance.
3) Tightly fixed retaining plate at the end of rod with two M3 x 8 screws and two M3 nuts.
4) At last, installation the positioin sensor to predetermined position according to installation requirement.

Cauction for magnetostrictive linear position sensor/displacement transducer
1) The position sensor is for an external installation, Open-ring magnet is selected. Mounting Kit FM-2 for stroke less than 1000mm while FM-3 for stroke greater than 1500mm.
2) FM-2 installed accessories only provide one Retaining plate, should be fixed within 25 mm to the end of rod.
FM-3 install accessories have three retaining plates, installation: One fixed in the end within 25 mm the other two are fixed on the rod.

We produce many other Magnetostrictive sensors such as: High precision type, Explosion-proof type, Standard type, Profile type and so on.
