The Series 631B Capuhelic® Wet-Wet Differential Pressure Transmitter measures the difference in pressure between two wetted ports. Unlike single-ended transmitters, both sides of this device can be exposed to pressure, making it ideal for liquid or gas differential measurement. The instrument maintains high accuracy and stable output even in challenging conditions. It is widely used in HVAC, filter monitoring, flow measurement, and liquid level applications.

Key Features:

Wet-wet differential pressure measurement capability

High accuracy and long-term stability

Suitable for both liquid and gas media

Durable construction for industrial environments

Standard output (e.g. 4–20 mA) for instrumentation systems

  • Gage 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 gage 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
