 Enter number of measuring points (1 – 6) in . Measuring up to 10 measuring points is possible by special order.
Coping with casing pipe in boring hole
Withoutsliding resistance of sensor
Constant tension tensioning device upon request

Used for multi-points rock bed displacement measurement of large underground cavern of underground power stations, large scale slopes incident to road or dam construction.
It consists of the transducer section that converts displacement into electrical signals, anchor sections which are fixed in multi-stage inside the bored hole, and the wire section which transmits the displacement of the anchor sections to the transducer.
Six anchors may be set in a bored hole of ø66 mm.
The transducer section is detachable to cope with casing pipe in boring hole.
