DWYER 631B Series, WET/ WET DIFFERENTIAL PRESSURE TRANSMITTER
Ranges Down to 0.5" w.c. with 500 psi Static Pressure RatingThe Dwyer Series 631B Capsuhelic® Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with accuracy. The design employs converting pressure changes into a standard 4-20 mA output signal for two wire circuits. Digital push-button, zero and span adjustments are easily accessed on the front cover. The Series 631 Differential Pressure Transmitter is designed to meet NEMA 4X ( IP66) construction. Robust housing offers 500 psi static pressure ratinng on ranges down to 0.5" w.c.
