Series 631B Capsuhelic® Wet/Wet Differential Pressure Transmitter
Brand: Dwyer Instruments, LLCThe Dwyer SERIES 631B Capsuhelic® Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with accuracy.
The design employs converting pressure changes into a standard 4-20 mA output signal for two wire circuits. Digital push-button, zero and span adjustments are easily accessed on the front cover.
The Series 631 Differential Pressure Transmitter is designed to meet NEMA 4X (IP66) construction. Robust housing offers 500 psi static pressure rating on ranges down to 0.5 inches WC.
Features- Gauge capsule permits high-pressure usage with small differentials
- Versatile device for liquid or gas supports designs requiring more precise measurements in support of application
- Zero and range adjustments outside of gauge means no disassembly in normal service
- NEMA 4X rated enclosure provides protection in harsh environments permitting outdoor monitoring or in areas where dust and particulate matter exists
