ATEX Zener barrier BZB20

multi-channelfor load cells

BZB20 zener barrier is a compact, three-channel safety barrier. It is designed to connect the analogue load cells of a scale or weighing system installed in an ATEX environment to a weighing indicator in a safe area. By using the BZB20, you can eliminate the problems of weight change with temperature, measurement stability, and weighing sensivity degradation that are caused by standard zener barriers in weight measurements. When using the BZB20 zener barrier in scales or weighing systems with multiple load cells, the voltage at the load cell excitation terminals will be 1.7 times higher than when using a standard zener barrier. As a result, more sensitive measurements will be obtained at the signal terminals of the load cells in the same ratio. With the use of BZB20, the drift in weight caused by standard zener barriers is eliminated, and in the hazardous area, the scale weighing performance and sensitivity used in non-hazardous areas are obtained.
