●
The set pressure and operating pressure are
indicated on the same pressure gauge. Panel
mounting offers convenient centralized control and
management built into the control panel.
●
An indicator is standard equipment, to check the
switch operation state. Wiring connection methods
offered include a standard grommet (lead wire) type,
and a DIN connector type as an option.

Notes 1: Shows when the pressure is rising.
2: Use a set pressure that has a differential of at least 14.5 psi with the supply pressure.
3: Regulating pressure indicator errors and repeatability errors could be accumulated.
