Caisson Method for Measuring Sensor KKA-PC

KKA-PC Caisson skin-friction meter　200kPa to 300kPa

The KKA-PC is a transducer to measure skin friction bearing force with the ground acting on thewall of concrete caisson. The transducer is installed so that the sensing area of the transducer faces thecaisson's wall and measures skin friction bearing force with the ground when settled and fixed.

Settlement Transducer KLA-A Settlement Transducer / NKLA-B TML-NET type Settlement Transducer

KLA-A Settlement Transducer
NKLA-B TML-NET type Settlement Transducer　100 mm to 200 mm

This is a settlement gauge that is set on a ground surface to measure the settlement of each ground layer. Special anchors are placed at target positions in a borehole, and the displacement between the anchors and the ground surface is measured. Measurement can be made at a maximum of six levels in one borehole.
* For information on network-capable NKLA-B, see special measurement systems.

Ground Extension Gauge KLG-B Ground Extension Gauge / NKLG-BB TML-NET type Ground Extension Gauge

KLG-B Ground Extension Gauge
NKLG-BB TML-NET type Ground Extension Gauge　100 mm

The KLG-B ground extension gauge is placed near the ground surface to measure the displacement of a ground slide. A superInvar wire is set between a stanchion at a reference point (fixed stanchion) and a stanchion at a measurement position (mobile stanchion) and this gauge is mounted on the stanchion at the reference point. The waterproof and environmental resistance features make this gauge suitable for on-site measurement work. The NKLG-BB model is designed specifically for use with the network measurement system TML-NET.

Surge Absorber Terminal

Surge absorber terminal SAT

These are terminals with built-in gas tube arresters for connecting transducers and instruments. The gas tube arrestor is a surge absorbing element to protect the connected device from surge voltage in the cable which is caused by induced lightning. Since the terminals are equipped with DIN rails, they can easily be installed in an instrumentation box and increased. Connecting works can be done easily and efficiently.

Surge absorber terminal SAT
Features
  • Most suited to installation in an instrumentation box owing to its small size
  • Most suited to protection of TML-NET wirings from thunderbolts
