Industrial Pressure Switch PSM-520 for Professional Applications

The PSM-520 pressure switch is a high-quality measuring device designed for professional industrial applications in control, monitoring, and alarm signaling systems. This model stands out due to its precise switch point adjustment capability and wide hysteresis regulation range, making it an ideal solution for installers and end-users seeking reliable pressure control.

Construction and Materials Ensuring Durability

The device is manufactured from high-quality materials resistant to typical industrial media. The diaphragm, made of CuSn6 copper alloy according to EN1652, ensures long-term resistance to wear and corrosion. The process connection, made of EN1A cutting steel according to EN10277-3, is additionally tin-plated, enhancing corrosion resistance and facilitating installation. Its compact design, with dimensions of approximately 127 × 85 × 48 mm and a weight of about 530 grams, enables installation in confined spaces.

Operating Parameters, Adjustment, and Electrical System

The pressure switch offers an adjustment range of 6-15 bar with hysteresis regulation between 1.5-5 bar, allowing precise adaptation of operating parameters to specific installation requirements. A maximum working pressure of 32 bar ensures a safe operating margin even during sudden pressure spikes.

Equipped with an SPDT (Single Pole Double Throw) switching contact, it enables switching of electrical loads at AC230V/50Hz with a current of up to 10A for resistive loads or 6A for inductive loads. The IP33 protection rating guards against dust and small water droplets, while the rubber cable gland allows safe connection of cables with diameters of 6-14mm. The factory default switch point setting can be easily adjusted on-site using the protective cover.

Industrial Applications and Media Compatibility

The PSM-520 model performs excellently in applications involving pumps and compressors, where monitoring and control of medium pressure are required. The device is suitable for use with non-aggressive media such as oils, water, and air. The medium temperature range of -20°C to +100°C enables deployment in both refrigeration systems and hot industrial processes, maintaining full functionality throughout the entire service life.
