Description

Series 629C Wet/Wet Differential Pressure Transmitter, 0.5% Accuracy, NEMA 4X (IP66) Enclosure

 

The DWYER Series 629C Wet/Wet Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4 to 20 mA output signal or field selectable voltage. DWYER Series 629C Wet/Wet Differential Pressure Transmitter small internal volume and minimal moving parts result in exceptional response and reliability. The terminal block, as well as a zero adjustment button, are easily accessed under the top cover.

 

Features

• Powered by either DC or AC – take advantage of most readily available power source reducing installation costs
• Optional LCD does not need a separate power supply – lowers installed cost
• Selectable voltage range – provides flexible choice for changing design or inputs for process/HVAC controllers being used to monitor and control
• Push button zero (versus trim pot) – more simple zeroing provides easy install and calibration reducing installation time and possibility of operator error
• Optional LCD indicator provides local status to identify operational condition
• Remote sensor option reduces installation labor and material
