Load/Pressure/Acceleration Measurement

The physical quantity which produces force can be measured through strains.
Typical examples of sensors that use strain are load / pressure / acceleration sensors.
The measuring unit can be measured by connecting with the 4-gauge system of strain.
* If it is a voltage output type instead of a strain gauge type, it can be measured with WM2000TA / TB.

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.

Dramatically Improves Operation Efficiency with a Cable-less Design

The wireless design significantly reduces man-hours for wiring work

Eliminates the hassle of cable routing even in places with lots of equipment.
The evaluation period can be shortened as the installation man-hours can be reduced.

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.

PC Communication Unit Max. 100 units

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.

NDIS conversion cable (option)

Conversion cable for connecting to various strain gauge type sensors with NDIS connector. The sensor can be easily installed.
It can be used with WM2000SA.
