Công tắc chênh áp suất gió Dwyer Model: ADPS / EDPS


Tính năng sản phẩm

The Series ADPS/EDPS HVAC Differential Pressure Switches are
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 are 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 compact size, adjustment knob and low cost make the
ADPS/EDPS the perfect choice for HVAC applications

• Air filter and ventilator monitoring
• Industrial cooling circuits
• Fire-protection damper control
• Ventilation duct monitoring
• Fan heater overheating protection
• Heat exchanger frost protection
