| RLP 100 F9..: Pneumatic volume-flow transducer
How energy efficiency is improved
Enables the demand-led control of the air volume in fume cupboards, laboratories and clean rooms.
Areas of application
In combination with an orifice plate or a dynamic pressure sensor, measurement of the actual volume flow in the case of dust-laden or contaminated air in ventilation systems.
Properties
- Square-root-extracted output signal can be used as a command variable for extended control loops
- Special version for the measurement of aggressive gases available
- ATEX certification for use in Zone 1 potentially explosive areas
- Conformity tested as per EN 13463-1 and EN 1127-1 (Ex II 2 G T6)
- Highly accurate, static differential pressure sensor with large measuring range (1 to 160 Pa)
- Controller front panel is printed with circuit diagram for rapid identification of function
- Glass-fibre-reinforced thermoplastic housing suitable for wall or top-hat rail mounting (rail EN 60715)
- Compressed-air connections with Rp 1/8" female thread
- Special measuring connection for recording the volume flow with M4 connector
- Low-pressure connections in form of stepped nipples for flexible plastic hose (internal Ø 4 and 6 mm)
