A3330 -15 to 0 to +15 (1.0) PhotohelicŪ Pressure Switch/Gauge by Kanomax
Two phototransistor-actuated circuits and two DPDT relays permit both high and low alarms or limit controls. Relays are denergized when gauge pointer is to the left of respective set points; relays are energized as pointer passes to the right of set points. Loss of electrical power or pressure provide fail-safe protection.
| Ambient temp. range | 20°F to 120°F |
| Rated pressure | 20 in. Hg. to 25 psig total pressure on either side of diaphram |
| Accuracy | ±2% FS at 70°F (3T on “0” model, 4% on “00” models) |
