Pressure Switch

Factory price refrigeration pressure switch for sale online, provides different pressure adjustment range options -0.2-32 bar/2-45 bar, the maximum working pressure can reach 48 bar, suitable for a variety of media such as refrigerant, air, water and oil. It is often used to control the pressure of the compressor in the refrigeration system.

Steam pressure switch provides a variety of pressure ranges (0.2-0.6bar, 0.5-1.0bar, 1.0-2.5bar, 2.0-4.0bar, 3.0-7.0bar, 5.0-9.0bar), and its operating temperature can be up to 125℃, suitable for high temperature steam environment. Single pole single throw (SPST) and single pole double throw (SPDT) contact modes are available.

Differential pressure flow switch is suitable for non-corrosive media such as water, air, and oil, with a wide range of differential pressure adjustment, including: 5-15kPa, 5-30kPa, 6-70kPa, 6-100kPa, 10-200kPa, 20-300kPa, and 30-400kPa. It uses a single set of SPDT micro-moving contacts, has an IP54 protection level, is dustproof and waterproof, and can be used in various industrial environments.

The digital fluid pressure control switch integrates pressure measurement, display, output, and control in one device. A silicon piezoresistive sensor provides the pressure signal, followed by low-drift amplification and high-resolution A/D conversion for accurate digital processing. Real-time pressure display, two switch outputs, and a 4–20 mA analog output enable reliable pressure monitoring and control across a wide range of 10 kPa to 100 MPa.

The smart LED pressure switch features a 4-digit LED display and an all-in-one design combining pressure measurement, control output, and monitoring. Using an oil-filled front end with a diaphragm-sealed piezoresistive sensor, the pressure switch supports a 0–600 bar control range and offers IP65 protection, suitable for both air and water. NPN, PNP, and 4–20 mA outputs provide compatibility for a wide range of hydraulic and pneumatic applications.
