In industrial measurement and control systems, safety is as critical a requirement as production continuity, especially in environments with explosive atmospheres. In these environments, signal and energy transmission between field devices and control units requires not only high accuracy but also an Ex-certified safety infrastructure. Solutions developed in this direction ensure the safe operation of field sensors and actuators while maintaining the stability of measurement signals, thereby guaranteeing system integrity. Thus, safety and measurement accuracy are combined in a single structure, creating a standard of reliability, continuity, and operational safety in industrial facilities.

This is precisely where the Baykon BZB10 and BZB20 Zener Barrier series come in, offering comprehensive and reliable solutions for measurement processes by combining safety, signal integrity, and system stability in weighing and process control systems used in explosive atmospheres.

The Baykon BZB10 and BZB20 Zener Barrier series are protection elements that provide safe energy and signal transmission between field devices and control equipment in weighing, pressure, temperature, and other measurement systems used in explosive atmospheres. Suitable for use in Zone 0, 1, and 2 hazardous areas, these barriers allow sensors or actuators in Ex areas to connect directly to equipment in safe areas while safely limiting the circuit in case of excessive current or voltage. Thus, the system continues to operate without compromising measurement accuracy and stability while maintaining Ex environment safety. With its compact design, DIN-rail mounting convenience, and long-lasting components, the BZB series offers a reliable, low-maintenance, and sustainable safety infrastructure for industrial facilities.

The BZB10 and BZB20 models are specifically designed for weighing systems that work with load cells, force sensors, and strain-gage-based pressure sensors. These models support connections for up to 4 load cells at 350 Ω and allow 4- or 6-wire load cells to be connected to the weighing device via 6 wires. This structure increases measurement accuracy by preventing signal loss and eliminates instability that may arise from temperature changes. Since the Zener barrier structure is optimized for direct load cell applications, it completely eliminates the disadvantages encountered in standard barriers, such as loss of sensitivity and accuracy, measurement stability, and thermal drift. Furthermore, all load cell power, signal, and sensor connections can be made through a single BZB module, reducing installation time while improving system organization and reliability. The product body is made of PC-ABS plastic, compliant with the UL 94 V0 flammability standard. Thanks to its compact box design, it can be easily mounted on a 35 mm DIN rail and provides resistance to industrial environment conditions with its IP20 protection class. With these features, the BZB series offers long-lasting, safe, and stable performance in all kinds of industrial scale, weighing scale, and weighing system applications.

The BZB10 and BZB20 models operate on the same safety principle but offer different advantages depending on their application. The BZB10 is a cost-effective, compact, and reliable solution for I/O connections of sensors, actuators, solenoid valves, and similar devices operating in Ex areas. Its three-channel DC structure, wide operating voltage range, and easy mounting on a 35 mm DIN rail enable space savings, easy installation, and low maintenance costs. Therefore, the BZB10 is an ideal barrier solution for general process automation, field control, and signal transmission applications. The BZB20 model, on the other hand, has been developed specifically for weighing systems operating in explosive environments that require high accuracy, stability, and thermal balance. It eliminates problems commonly seen in standard Zener barriers, such as temperature-induced weight drift, measurement instability, and loss of accuracy. By providing 1.7 times higher supply voltage in multi-load cell systems, it increases signal accuracy and enables weighing performance as precise as measurements taken in a safe environment. Furthermore, the ability to connect load cell power, signal, and sensor connections through a single module simplifies the installation process and increases system reliability. The BZB20 stands out as the most reliable and efficient solution for weighing systems requiring high accuracy, thermal stability, and long-term performance.

In conclusion, Baykon BZB series Zener Barriers are advanced protection solutions that combine explosive environment safety with measurement accuracy. Developed for different needs, the BZB10 and BZB20 models ensure both process safety and system stability by providing safe energy and signal transmission. With their compact design, easy installation, and durable construction, these products offer long-lasting, reliable, and sustainable use in Zone 0, 1, and 2 hazardous areas. This allows businesses to maintain production continuity while minimizing risks by fully complying with Ex environment safety standards.
