WIKA has announced the launch of an automatic heavy-duty pressure switch named PSM-630. The pressure switch can work on both 3φ and 1φ connections. The instrument can switch electrical loads of up to AC 440 V, 16 A. The switch provides added functionality and safety as it can be manually adjusted by the customer on-site along with the automatic cut-off within the prescribed range. PSM-630 has an integrated relief valve to ensure a smooth restart of the compressor. It features a single process connection that is threaded in four different ways for accommodating safety valves and other types of switches. The automatic heavy-duty pressure switch has been designed for applications such as air compressors and water pumps.
The India-based company says that the product has been developed for customers who are looking for a flexible but safe pressure switch. It can switch electrical loads of up to 16A, 440 VAC. The integrated relief valve is used for depressurising the pressure chamber of the compression piston before starting the compressor. For additional safety the switch comes with a manual on/off knob, that can allow the contact knob system to lock in the open position, irrespective of the process pressure. Among the other safety measure, the switch cannot be easily tampered with as the process connection is done through forging or casting. The switch has a snap-action mechanism inbuilt into it—thus it stops automatically once the pressure reaches the defined particulars thus causing no side effects to the machine itself
Mr Gaurav Bawa, Sr Vice President, WIKA India said, “PSM-630 is being launched in India after market research and alignment with the requirement of the customers who were looking for a flexible but safe pressure switch. This is one of the many products in the line that WIKA is planning to launch in Indian markets. PSM-630 is customized for the Indian market and we feel that its accessible design, inbuilt safety features and versatile application options will find good market acceptance.”
The versatile PSM-630 can be used in a wide variety of applications that include industrial control, monitoring and alarm applications.
