The Dwyer 3030SGT-N02Z-D Photohelic Pressure Switch Gage combines a dial pressure gauge with an integrated photohelic switch for automatic electrical control at a calibrated pressure. This model belongs to the 0-30 series and is identified as 3030SGT-N02Z-D, designed for process monitoring and control where a pressure readout is paired with a switch output. With both live pressure indication and a switch action, it supports simple integration into control circuits for alarms, interlocks, or equipment control.
