Small size and high performance capability make our differential pressure switches ideal for most process applications. Minimum static working measurements of 500 PSI allow use on the most difficult filter applications. We use a unique combination of diaphragm-sealed piston actuators to get our high static differential pressure switches performance in 12 ranges. For inches of water ranges, we use a large diaphragm for sensitivity which results in lower, more conventional working pressures with differential switches.
