| RLP 100 F9..: Pneum. room-pressure controller
How energy efficiency is improved
Enables the precise measurement and control of pressure differentials in clean rooms or laboratories without creating additional pressure compensation openings which lead to unnecessary losses of energy.
Areas of application
Room pressure control of extremely well-sealed rooms, e.g. clean rooms or laboratories (up to BSL-4).
Features
- Fast, accurate control system in combination with RLP 100 pneumatic volume-flow controllers
- Accurate static sensor, can also be used in areas with contaminated room air
- Measuring ranges up to max. ± 185 Pa
- 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)
- Controller's front panel is printed with diagrams for rapid identification of functions
- 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 room pressure with M4 connector
- Low-pressure connections in form of stepped nipples for flexible plastic hose (internal Ø 4 and 6 mm)
- Complies with Pressure Equipment Directive (PED) 97/23/EC Art. 3.3
Technical description
- Supply pressure 1.3 bar ± 0.1
- Response sensitivity of sensor 0.1 Pa
- Non-linearity 1%
- One input for:
- remote setpoint adjustment
- Two outputs for:
- actual volume of room pressure
- command signal for volume-flow controllers (shift)
- Setpoint adjuster for room pressure (minimum limitation for room pressure when setpoint is adjusted remotely), plus adjusters for Tn and Xp
