The 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.
