Dwyer德威爾 BDPA-30/04/05/06/07/08-2-N 差壓開關(guān)報警器

The SERIES ADPS/EDPS/BDPA/BYDS Adjustable Differential Pressure Switch is

designed for pressure, vacuum, and differential pressures. The dual scaled adjustment

knob in inches water column and pascals allows changes to the switching pressure to

be made without a pressure gage. The ADPS/EDPS/BDPA is available with settings

from 0.08 in w.c. (20 Pa) up to 20 in w.c. (5000 Pa). The silicone diaphragm and PA

6.6 body make the series ADPS ideal for use with air and other noncombustible gases.

Series EDPS models meet UL508 and are constructed of plenum rated plastics.

The series BDPA Adjustable Differential Pressure Alarms offer a versatile range of

configurations allowing utilization of their many features including buzzer and LED

notification, and battery or line powered. The compact size, adjustment knob and low

cost make the ADPS/EDPS/BDPA the perfect choice for HVAC applications.
