Belimo 22WDP-111 - liquid differential pressure sensor

Belimo 22WDP-111 – differential pressure sensor

Active sensor for measuring differential pressure in HVAC systems. The technical data sheet indicates suitability for use with water, a water-glycol mixture and steam; it also describes suitability for liquids, refrigerants and non-aggressive gases.

Key parameters

• Differential pressure measuring range: 0...1 bar; 0...15 psi.
• Output signal: 1 x 0...10 V, min. resistance 2 kΩ.
• Rated voltage: AC/DC 24 V.
• Pressure connection: G 1/4".
• Electrical connection: plug connector for 0.5...1.5 mm² cable.
• Degree of protection: IP65 / NEMA 4.
• Differential overpressure: 6 bar; negative differential overpressure: -1 bar; burst pressure: 21 bar.
