Strain measurement is used to check various phenomena as any object may be distorted when force or energy is applied.
The measurement method using a strain gauge is done by attaching a strain gauge, of which resistance value changes depending on the change of shape, with an adhesive or the like,
while minute resistance changes are extracted and detected by a Wheatstone bridge.
Ultra-Compact and Lightweight
The bridge resistance, amplifier, recorder, and radio are all built into the measurement unit.
The drive power supply is merely a small battery.
With its compact and lightweight structure, it can be set up near the measurement target,
eliminating the trouble to route the huge amount of wiring required by the conventional method.
Wireless measurement of moving parts eliminates the need for measurement jigs
Wireless technology allows evaluation of the actual machine without having to use slip rings or measurement jigs.
The wireless design significantly reduces man-hours for wiring work
AirLogger™ can shorten the evaluation period because it reduces man-hours required for measurement.
Reduction in wiring man-hours will relieve the hassle of routing cables.
Enables measurement from inside a metal housing
If there is a gasket or a window, it is possible to measure by wireless communication even in a temperature test chamber.
With the WM2000 series, you can check the radio wave condition on the software.
Capable of Real-Time Simultaneous Measurement at Multiple Measurement Points
The measurement units can be synchronized
by the synchronization signals from the PC communication unit.
Synchronous measurement of up to 100 units is possible.
The measured data can be checked in real time with standard software.

Filtering Data after Measurement
You can create a filtered file from the data measured by standard software.
With the standard software, you may use the low-pass filter function to remove fine noise and data with DC components removed using a high-pass filter.
Resampling after Measurement
You may create a file with less data by thinning out/resampling the measured data.
When outputting the measured data, of which were originally finely measured, in a csv file, you can roughen the sample to so that the data can be lessened when extracted.
This method can be applied when performing envelope detection by using a conversion formula at the time of measurement, and by using a filter function to thin out data after measurement.
Delivering Wireless Measurement that “Connects”
Memory data is stored using the internal memory of the measurement unit and has a recovery function.
The strength of the transmitted and received radio waves varies significantly depending on the way the measurement unit and the PC communication unit are installed.

Ultra-compact and Low Noise, with No Need for an AC Power Supply
Since it is battery operated, it has the advantage of being less affected by power supply noise, which is difficult to remove.
It can be used in a high-voltage environment by installing the housing of the measurement unit with insulation.
(However, extreme care is required under high voltage since it cannot withstand high voltage between channels of the same measurement unit.)
Waterproofness/Dustproof performance is equivalent to IEC standard IP54 compliant. (The performance shown is the use of a waterproof attachment)
Measurement File Format
Measurement data can be output as a csv file.
