Product outline

EtherCAT® is a registered trademark and patented technology, licensed by Beckhoff Automation GmbH, Germany.
Applicable from fast response measurement to multi-weighing with high accuracy!

High sampling rate & resolution

High-Speed A/D conversion and powerful digital processing capability of 1200 times/sec..
High display resolution of 1/100000 (max).

Measurement can be performed quickly and precisely due to high speed A/D conversion.
Application software for USB interface

With communication through USB interface, logging, graph, display, setting parameters, and calibration can be done.

High performance filter & Auto filter adjustment

With combination of low pass filter (0.1 to 300Hz) which corresponds to various vibration and moving average filter (OFF, 2 to 512) that is effective for periodic vibration, automatic searching for optimal value with accuracy and stability can be achieved.
(You can manually adjust settings too).

Lightweight and compact body to fit into limited space in a control panel

Light weight & compact body for 35mm DIN rail mount.
Dimensions : 34(W)×88(H)×91(D)mm (Projections excluded)
Weight : Approx. 230g


Various interfaces


Load cell signal level display (-2.51mV/V to 5.1mV/V)

The output signal level of load cell can be displayed in mV/V for monitor purpose.
Malfunction indicator or faulty sensor can be differentiated easily.

6 digit display

24 bit A/D convertor enables 6 digit display.

Equivalent input calibration

Theoretical calibration can be performed easily by registering the capacity and rated output of load cells.

Multipoint calibration (linearization)

Three additional points can be defined in the middle between zero and span for better linearity.
Even though the scale has poor linearity, it can be corrected to be a highly accurate scale.
