OMEGA’s PSW601 series switches are designed to provide long stable life. They use a thin film sensor with a minimum life of 1 million cycles. Solid state circuitry analyzes the signal from the sensor to activate the switch at the setpoint. Deadbands are adjustable from 0.1% to 95% of range and status lights give a visual indication of switch status.

My system runs at 20,000 psig. Can this switch be set to 20,500 psi (or special ordered)?

Asked by: Scott H
The maximum setpoint is for the PSW601-20K is 20,000 psi. It cannot be set to a value above that. A custom version with a higher setpoint capability is not available.
