Dwyer Series 603A Differential Pressure Transmitters

4-20mA, 2, 3 or 4 Wire Operation. Ranges from 0.1" w.c. Accurate w/in 2% F.S.
 

Dwyer Series 603A Differential Pressure Transmitters combine ultra low ranges, low cost, high accuracy and rugged construction - ideal for a wide range of HVAC and industrial applications. These transmitters provide a standard 4-20 mA analog output signal in ranges as low as 0.2" w.c.

The transmitter can be surface mounted or flush mounted in a 4-13/16" (122 mm) diameter panel hole. Hardware is included for either option. Duplicate 1/8" female NPT pressure connections on side and back ease installation.
