Description
The DPA-43-153-65E is a 316 stainless steel double bellows switch rated 80 psid with adjustable deadband. The Dwyer Model DP differential pressure switch uses two opposing bellows to sense the difference between two pressures. This design gives high sensitivity, fast response to changes, and good vibration resistance. Setpoints are set with external knobs against a large scale that reads directly in psid. The DPA versions listed here use 316 stainless steel wetted parts for broad media compatibility, and are used to monitor filters, pumps, and flow across process equipment.
