Germany's Beck GmbH specializes in producing differential pressure sensors, differential pressure switches, and pressure switches that are widely used in power plants, HVAC systems, air conditioning, and pharmaceutical industries. The prices are extremely competitive, making them highly cost-effective compared to similar brands on the market. The company is a professional manufacturer of micro-differential pressure products, with full capabilities in development, research, and production. It also offers various customization and OEM services for its products. Beck's pressure switches and pressure transmitters can be used in many different fields to measure differential pressure, gauge pressure, and absolute pressure. The modular design allows users to integrate solutions themselves at low cost. Of course, the products can also be used independently. The pressure switch features a triggering mechanism controlled by a diaphragm pressure, and the switch can also be adjusted with vertical springs. If the set value exceeds the range, the contact is activated to stop or shut down. Within a wide range, the pressure switch value can be preset or user-defined. The pressure transmitter is equipped with a resistive pressure sensor that functions as an active component to continuously monitor pressure. All pressure transmitters provide current or voltage output, and some models can also function as switch outputs. They can also be equipped with on-site digital displays for real-time monitoring.
