AWHU-5/AWHU-8CE_logo

These gauges can be used in temperature up to 800°C for both static and dynamic measurement. However, owing to the construction of the sensing element, measurement is recommended in temperature at 600°C or above. The sensing part has half bridge configuration with active element and dummy element, and it is measured in full bridge method using the attached temperature compensation circuit board. Since these gauges have small backings and thin sleeves and cables as standard specifications, they are applicable to narrow and/or curved areas.

*“FOMA”, the 3rd generation mobile communication system, will terminate its service on 2026/3/31. 
Please be careful if you are using FOMA network compatible model FPT-Em/DMA-S/DMA-ES. 

Option

Inclinometer and rainfall option version TDS-Mail-F

  • Rainfall Measurement

Rainfall measurement is made possible by counting the contact pulse signal from the tipping rain gauge using the NSW-01C network module or the built-in contact input of the MD-111 monitoring system controller. 

The total rainfall, hourly rainfall, and 24-hour rainfall are calculated from the rainfall counts. 

  • Quadrature Calculation

Four-Way Calculation Using Measurement Channel Data

  • Multi-stage inclinometer - horizontal displacement measurement

Extended data can be created for each borehole and horizontal displacement distribution graphs can be displayed

Concrete Moisture Sensors KZW-1A

Concrete Moisture Sensors KZW-1A

Directly monitoring changes in moisture content in concrete is a rational and very effective method for quality control of concrete. 
Concrete Moisture Sensor can estimate the free water content (evaporable water at 105°C) of concrete from fresh concrete to hardened concrete by electrically and nondestructively monitoring changes in moisture content inside the concrete continuously from immediately after placement. 
This can be applied to determine the state of curing, the timing of formwork removal, and the timing of surface finishing. 
It can also be used for versatile purposes in fields such as research on hydration of concrete, which is closely related to the water content in concrete, durability, and maintenance management. 

Protection ratings: IP67 equivalent
