Pressure increase/decrease

Pressure increase and decrease devices, commonly referred to as pressure switches, pressure transmitters, or pressure regulators, are critical components in industrial automation and fluid power systems. These devices monitor and control the pressure of gases or liquids within a defined range, ensuring system stability and safety. Key technical parameters include set point range, hysteresis, switching capacity (e.g., 10A at 250V AC), electrical connection type (e.g., DIN plug, cable gland), and process connection size (e.g., G1/4, 1/4 NPT). Pressure switches can be electromechanical or electronic, with adjustable or fixed differentials. Pressure transmitters provide a continuous analog output signal (e.g., 4-20 mA, 0-10 V) proportional to the measured pressure, while pressure regulators maintain a constant downstream pressure regardless of upstream fluctuations. These devices are available in various pressure ranges, from vacuum to high-pressure applications up to 600 bar, and with different enclosure ratings such as IP65 for harsh environments.

These devices are widely deployed in hydraulic and pneumatic systems, water treatment plants, HVAC systems, compressor stations, and industrial process control panels. In hydraulic systems, pressure switches protect pumps and actuators from overpressure conditions. In pneumatic systems, they ensure consistent air supply pressure for valves and cylinders. In water treatment, pressure transmitters monitor filter backwash cycles and pump discharge pressures. They are also essential in safety circuits for emergency shutdown systems and in packaging machinery for clamping force control.

Our category includes subcategories such as electromechanical pressure switches, electronic pressure switches, pressure transmitters, differential pressure switches, and pressure regulators. Key article codes follow a structured format: for example, a standard pressure switch might be coded as "PS-1A-10G" where "PS" denotes pressure switch, "1A" indicates the set point range (e.g., 1-10 bar), "10G" specifies the process connection (G1/4). Another example is "PT-4-20MA-100B" for a pressure transmitter with 4-20 mA output and 100 bar range. We also stock compact pressure switches like "CPS-0.5-5B" for low-pressure applications and high-pressure models like "HPS-100-600B" for hydraulic systems. These codes help engineers quickly identify the device specifications for their application.
