Key Facts
- For accurate measurement in Zone 0/1/2 or Zone 20/21/22 explosive atmospheres; Connection of load cells, force sensors and strain gauge based pressure sensors, All kinds of industrial scales, scales and weighing systems.
- The Zener barrier design is intended for the load cell. It eliminates the sensitivity and accuracy degradation, measurement and thermal stability problems caused by standard zener barriers in weighing with load cells. Load cell excitation, signal and sense connections are all made via a single BZB20.

Product information
The BZB20 zener barrier is a compact, three-channel safety barrier 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 issues such as weight change with temperature, measurement stability, and weighing sensitivity 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 termin ...Product Expert
