Our standard transducers are designed with the following output polarity for measurement.

Displacement Transducer CDP, SDP, DDP
 

Measured value changes in negative (-) direction when the shaft is depressed.

Displacement Transducer DP

Measured value changes in positive (+) direction when the wire is pulled out.

Displacement Transducer OU

Measured value changes in negative (-) direction when the contact tip is depressed as in the right figure.

Displacement Transducer CE

Measured value changes in negative (-) direction when the contact tip is depressed as in the right figure.

Pressure Transducer PW

Measured value changes in positive (+) direction with increase of pressure.
Water Level Meter KW-C and Pore Pressure Gauge KPC/KPD are the same as above.

Load Cells

Measured value changes in negative (-) direction with increase of compressive load (for compression load cell), while it changes in positive (+) direction with increase of tensile load (for tension load cell).

Flange Mounting-Type Torque Transducer LTB-NA

Moves in the plus direction when torque acts in the direction of the arrow (right-turning) with regard to the flange.

Displacement Transducer PI

Measured value changes in positive (+) direction with increase of crack opening displacement.

Crack Displacement Gauge KG-A

Measured value changes in positive (+) direction with increase of crack opening displacement.

Ground Extension Gauge KLG-A / KLG-B

Measured value changes in positive (+) direction when the wire is pulled out.

Micro-Creep Meter KH-A

Measured value changes in positive (+) direction when the distance between two points inicreses.

Soil Pressure Gauge

Measured value increases in positive (+) direction with increase of pressure.
The Load Cell type KDG/KDH/KDJ/KDK models are the same.

 

Rock Displacement Transducer KLB-B

Measured value changes in positive (+) direction when the distance between the transducer and the hydraulic anchor increases.

Settlement Transducer KLA-A

Measured value changes in positive (+) direction when the distance between the transducer and the hydraulic anchor decreases.
