Construction

The WTB transmitter has a 6-digit weight and service display. The weight value can be controlled locally by the well-read, bright LED display. The four buttons are behind a hinged acrylic glass plate on the front. The scale transmitter is designed for installation on a standard DIN rail. The narrow design allows the installation of multiple devices next to each other. Both 4 - and 6-wire load cells can be connected. The peak value function (PEAK) can be linked with a switch point output of a serial interface, analog output, or display.

Weighing technology - Legal for trade

The scale transmitter of the WTB series are legal for trade according to OIML verification class III and IIII. The weighing function is authorized up to 10,000 components. The calibration and function setting is made easy via the keypad. A theoretical calibration - without weights - only by entering the weighing range and the nominal characteristic value of the load cell (mV / V) is also possible.
