Digital dynamic strainmeter DRA-162B

Digital dynamic strainmeter DRA-162B

This carrier wave type dynamic strainmeter is designed for on-line measurement using a personal computer. 
Input waveforms are continuously digitized, recorded in the internal memory, and transferred to a PC. 
Since dynamic phenomena can be captured numerically, data analysis using a PC is easily possible. 
Equipped with a data memory of 256k words/channel, data trigger start and pre-trigger recording are also possible. 
It also provides analog outputs similar to those of ordinary dynamic strainmeters. 
All operations are performed from a PC via a LAN interface. 
In addition to strain gage and strain gage transducers, voltage measurement is also available.

Digital dynamic strainmeter DRA-162B
Features
  • Built-in 16-bit A/D converter for each channel, waveform recording by digital value 
  • Built-in 256k words/channel data memory (for 16 channels) 
  • Remote sensing of bridge voltage minimizes sensitivity degradation during cable extension (up to 100 m) 
  • Each setting can be PC-controlled 
  • Data backup possible on the main unit of the instrument 
  • Bridge voltage switching (0.5 VAC, 2 VAC) can be set independently for each channel 
  • Built-in check functions (sensitivity, input open, over, insulation) 
  • Capable of transferring recorded binary data over a LAN at a rate of approx. 500 kwords/second 
  • TEDS sensor data readable

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

Concrete Moisture Sensors KZW-1A
Features
  • Real-time confirmation of distribution and changes in free water content in concrete 
  • Applied voltage method 
  • Monitoring of many measuring points and on-line measurement with a PC using our data logger 
  • Compact and lightweight, does not affect the quality of concrete after construction.

Concrete Filling Sensors KZA-1C

Concrete Filling Sensors KZA-1C

This sensor is designed to monitor the filling status of concrete in the formwork. 
By attaching the sensor to any location to be monitored and connecting it to a measuring instrument, the filling status can be monitored in real time. 
This sensor is particularly useful for quality control of construction work in confined spaces where it is difficult to check the filling status by compaction or visual observation, such as the flowability of high-fluidity fresh concrete in structures with high-density reinforcement. 

Concrete Filling Sensors KZA-1C
Features
  • Discrimination between materials with different electrical conductivities, such as fresh concrete, bleeding water, air, etc. 
  • Applied voltage method 
  • Compact, lightweight, and thin 
  • Measurable with our static strainmeter (TDS series)
