Product Description

 Magnetostrictive displacement sensor:

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

Features

1) high precision 0.05% FS

2) durable, hermetically sealed design

3) anti-interference ability, lower working current

4) non-contact measurement, no wearing

5) zero point adjustable scope to full range

6) support two places measurement at the same time

Application:

1) oil cylinder and air cylinder, hydraulic cylinder position detection

2) oil tank, medicine bottle reservoir etc level measurement

3)valve, gate open degree testing

4) mechanical equipment mobile location feedback

5)injection molding machine template orientation and monitoring

Installation steps：

1) 1) Stuck sensor 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 × 16, 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 sensor to predetermined position according to installation requirement.
