The Series MP Mini-Photohelic® Differential Pressure Switch/Gage combines the time proven Minihelic® II differential pressure gage with two SPDT switching set points. The Mini-Photohelic® switch/gage is designed to measure and control positive, negative, or differential pressures consisting of non-combustible and non-corrosive gases. Gage reading is independent of switch operation. Switching status is visible by LED indicators located on the front and rear of the gage. Set points are adjusted with push buttons on the back of the unit.

Your catalog says the A3000 series photohelic needs 120VAC, but "Special units for other voltages are available." Does that mean I can order a 24VDC model? If so, what would the part no. be? Thanks
We do offer two voltage options which are -24VAC: 24 VAC Relay Pack or -240 VAC: 220/240 VAC Relay Pack.
Unfortunately we do not offer a VDC option with the A3000 Series. However, you could consider the Series MP, Mini-Photohelic Differential Pressure Switch/Gage or the Series 3000 MR or 3000 MRS which all offer the 24 VDC Power Requirement.
