BDPA-03-2-N

BDPA-03-2-N is a series BDPA adjustable differential pressure alarm with built-in audible and visual set point indication is designed for overpressure, vacuum, and differential pressure applications. The scaled adjustment knob allows changes to the switching pressure to be made without a pressure gauge. The series BDPA can be powered by battery or 24 VDC/VAC line power. If connecting line power, the battery can act as back-up power in case of power outage. When set point threshold is reached, a local loud audible buzzer and bright LED will indicate periodically notifying of set point activation. An SPDT contact may also be wired to send a signal remotely to a DDC or building management system. Typical applications include air filter and ventilator monitoring, industrial cooling circuits, fire-protection damper control, ventilation duct monitoring, fan heater overheating protection and heat exchanger frost protection.
