About this item
The WIKA DPSM-550 is a heavy-duty, mechanical differential pressure switch designed to monitor, regulate, and control pressure variances between two distinct points in fluid or gas systems. Built under the trusted WIKA Indfos name, this instrument operates purely mechanically without the need for external electronic power supply. It uses a flexible bellows or diaphragm sensor assembly to actuate an electrical micro switch whenever the difference between the high and low-pressure inlets reaches a user-defined setpoint.
