Pressure Sensor – Series 520
-1 ... 9 bar / 0 ... 2.5 – 1000 bar

The Series 520 pressure sensor utilizes thick-film technology developed by Huber+Suhner. The pressure sensor chip is welded onto the pressure port, making it suitable for all gaseous and liquid refrigerants in the refrigeration industry, including ammonia. The Series 520 pressure sensor combines a unique integrated circuit design, offering superior electromagnetic compatibility and high accuracy within its temperature range. It is widely used in various industrial automation technologies such as refrigeration, hydraulic, and pneumatic control.Medium:
