PSM-520-200 Wika (Indfos) Pressure Switch , The model PSM-520 pressure switch is an electro mechanical instrument that senses changes in pressure and provides electrical on-off contact at predetermined pressure values.The PSM-520 may be used to energise an alarm or directly control the process by cycling pumps, shifting valves etc. In an alarm application, the switch supports valuable equipment by signalling an alarm. In direct control applications, the switch can be linked electrically to other equipment. PSM-520 pressure switches are designed for use with oil, water, air, steam and other non-corrosive pressure media.They are not suitable for use with refrigerant gases. This pressure switch is cost-effective and used in a wide variety of applications such as pumps, compressors, turbines, lubrication systems and condensers.

PSM-550 pressure switches utilize seamless bellows as the sensing element. Simplicity of design and easy of installation has been stressed for reliable use, even in applications where shock and vibrations are present. The sensing element is suitable for a variety of process fl uids. PSM-550 switches have an excellent record backed by our responsive manufacturing facility. Special application assistance is always available. Switzer data sheet PSM-550 Switzer data sheet PSM-550 ∙ Applications include pumps, compressors, filters, evaporators, heat exchangers, lubrication systems, hydraulic systems, marine equipment, heating and air conditioning equipment, turbines, generators and circuit-breakers etc.

Model PSM-530 pressure switches are essentially designed for on‑off pressure control applications such as air compressors or water pumps to control their working between the minimum and maximum setting values. At the maximum setting value, pressure switch contacts open and stops the motor. At the minimum value, pressure switch contacts close and start the motor.
