Series 629 Wet/Wet Differential Pressure Trans
Brand: Dwyer Instruments, LLCThe SERIES 629 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 4-20 mA output signal for two wire circuits. Small internal volume and minimum moving parts result in exceptional response and reliability.
Terminal block, zero and span adjustments are easily accessed under the top cover. The Series 629 Differential Pressure Transmitter is designed to meet NEMA 4X (IP66) construction.
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
- Span and zero controls reduce installation and service time
- Terminal block reduces wiring difficulties saving installation time
- Optional LED indicator provides local status to identify operational conditions
- Optional 3-way valve manifold supports higher line pressures or simplifying removal of transmitter without interrupting process
