| RLP 10: Pneumatic volume-flow controller
How energy efficiency is improved
For demand-led control of the air volume in office rooms.
Areas of application
Control of the supply and exhaust air of individual rooms or duct pressures. Can be used in potentially explosive areas.
Properties
- 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)
- Control of constant, switchable or variable air volumes
- 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
