Dwyer 629C Series Offers

Features

• Versatile, high accuracy device for liquid or gas supports designs requiring more precise measurements in support of application
• Minimum components provide excellent response and reliability
• Zero control reduces installation and service time
• Terminal block reduces wiring difficulties saving installation time

New 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 ranges on voltage units – provides flexible choice for changing designs or matching inputs for controller equipment being used to monitor and control. Additionally minimizes number of stocked units.
• Push button zero (versus trim pot adjustment)– easier more simpler zeroing provides easy install and calibration reducing installation time and possibility of operator error.
• Rugged NEMA 4X enclosure even with optional LCD permits use in many environments.
• Locking Hex nut connection prevents inadvertent stripping out of process connection.
