|  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.
