Deskripsi Dwyer ADPS-03-2-N Differential Pressure Switch

FUNGSI: UNTUK MENGETAHUI KEADAAN FILTER. SERING DIGUNAKAN DI HEPA FILTER.
OUTPUT: SWITCH
SET POINT RANGE: 50-500PA

ADPS-03-2-N Adjustable differential pressure switch, set point range 0.20 to 2.00″ w.c., M20 connection.

The Series ADPS/EDPS 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.
