TRIPLE zener barrier for load cells ZBA1S

A zener barrier for load cells is an essential safety component in explosive environments, such as the chemical, pharmaceutical, and oil and gas industries. This barrier protects weighing systems by limiting voltage spikes and unwanted electrical signals, thereby minimizing the risk of sparks and explosions. Zener barriers work by safely dissipating excess energy to earth, keeping the electrical load on load cells and other measuring equipment within safe limits.

In combination with load cells, a zener barrier not only provides safety, but also ensures the accuracy and reliability of measurements in challenging conditions. This makes it possible to perform reliable weighing processes, even in potentially hazardous areas, without compromising the safety or accuracy of the equipment.

Installing a zener barrier in explosion-proof areas complies with international standards for intrinsic safety (such as ATEX), providing businesses with additional peace of mind. By investing in a zener barrier for load cells, businesses can not only meet strict safety guidelines, but also obtain uninterrupted and accurate measurement results, which is essential for safe and efficient business processes.

The Zener barrier ZBA1S is the ideal solution for the connection between a terminal and a weight receiver system in the ATEX ZONE. ZBA1S integrates three barriers in one and protects the excitation line signal and sense. This feature makes installation easier, especially in small spaces. This saves time and money. Single barrier marking: ATEX II (1) G, II (1) D, I (M1) Protection: [Ex ia Ga] IIC, [Ex ia Da] IIIC [Ex ia Ma] I (-20 ° C ≤ Tamb ≤ 60 ° C)
