A3000 Series Photohelic® Micro Differential Pressure Switch / Meter
product description:
The A3000 series Photohelic® micro differential pressure switch /
meter uses the reliable and durable Magnehelic® design concept, which combines a high precision differential pressure gauge and a highly repeatable differential pressure switch. Can measure and control the positive, negative or differential pressure of air or other compatible gases. The standard pressure rating is 25 psig (1.7 bar), and 35 psig (2.4 bar) or 80 psig (5.5 bar) can be selected. The 36000S single pressure version can measure 6000 psig (413 bar) and withstand pressures up to 9000 psig (620 bar). Two double-pole double-throw switches are used for high / low limit control. The knob on the instrument panel can easily adjust the set points. The return difference of each set point is less than 1%, which is narrower than the width of the pointer. The use of two set points can lock out different hysteresis and is most suitable for controlling fans and dampers. The differential pressure gauge reading is not affected by the switching operation, even if the power is lost, it will not affect the reading. Selectable measuring ranges from 0-0.25 inch water column (0-6 mm water column) to 30 psi (2.1 bar).
How Photohelic works
When the differential pressure between the high and low setpoint values reaches a certain setpoint, the linked light-shielding plate will block the infrared beam directed at the limit transistor, so that the transistor signal is amplified and triggers the double-pole double-throw switch action. .
Features
Protect all electronic components and circuits with an engineering plastic case. The solid-state switch and electronic components are fixed on the epoxy-protected circuit board and have a flame-retardant terminal block.
