Wireless weighing indicator A12EWS

The A12EWS wireless weighing indicator is used in various types of platform and commodity scales. A weight indicator is also used in simple bunker scales.

The wireless weighing indicator A12EWS is the “older” model of the A6 indicator.

This wireless indicator A12EWS is an innovative solution in the field of industrial weighing. The A12EWS indicator is particularly reliable, easy to operate and at the same time low cost.

The scope of use of the A12EWS indicator is the production of various types of platform, truck and bunker scales.

The main use of the A12EWS indicator is data transmission in difficult places where scales are installed, where there is no possibility of a wired (cable) connection of the primary weighing equipment (strain gauges) with the secondary (weighing terminal).
The advantage of this weighing solution is operation at a great distance from the weighing system (up to 300 – 500 m), display of the ADC code, low-voltage power supply DC9V-DC6V, as well as the use of stainless steel components.

This A12EWS weighing indicator is particularly reliable, low power consumption, easy to operate and at the same time low cost. Functionality identical to the A12 weighing indicator.
