Pressure Switches & Sensors
PWTB Series Wet Pressure Sensors
The PWTB Series Wet Differential Pressure Sensors provide reliable, accurate measurement for controlling and monitoring liquid, gas, and vapor based systems.
- Demand measurement in HVAC systems for pump speed control and local monitoring
- CW/HW system differential pressure
- Chiller/boiler differential pressure
- Process control systems
- Flow measurement of gases, vapors, and liquids compatible with 316L SST
- System leak detection
Features & Benefits:
- Up to five selectable ranges plus high resolution mode for lower pressures.
- User friendly LCD displays in PSID or kPa.
- Absolute mode outputs absolute value of difference.
- Port swap corrects plumbing errors.
- NEMA 4X rated enclosure
- Uni/bi-directional modes.
- Test mode: Forces full-scale output.
- Over range icon warning.
- Switch selectable outputs: 2-wire 4-20mA, 3-wire 0-5V or 0-10V.
- High reliability withstandard integrated snubbers protect sensing elements from water hammer damage.
- Reduced plumbing complexity and cost with remote mounted transmitter and wired pressure transducers.
- No bypass required for installation as sensors can be installed in tees or elbows for simple air bleeding.
- Pre-wired plenum and armored cable versions minimize wiring issues.
