RLP 10 F9..: Pneumatic volume-flow transducer

How energy efficiency is improved
Enables the accurate recording of volume flows for the optimisation of energy consumption in ventilation systems.

Areas of application
Measuring actual volume flow value using a suitable dynamic pressure sensor

Properties

• Conversion of pressure difference by means of a square root extracting transducer into a linear flow signal
• Application of output signal as a command variable of a volume flow controller in the supply air
• Static differential pressure sensor with large measuring range (10 to 250 Pa)
• Controller front panel is printed with circuit diagram for rapid identification of function
• Thermoplastic housing suitable for wall or top-hat rail mounting (rail EN 60715)
• Compressed-air connections with Rp 1/8" female thread
• Low-pressure connections in form of stepped nipples for flexible plastic hose (internal Ø 4 and 6 mm)
• Complies with directive 97/23/EC Art. 3.3 on pressure equipment
