Suitable for extreme cases when the Ø 0.8 mm restrictor (accessory 0977) does not provide sufficient attenuation. Not suitable for volume flow controllers (RLP00F94, F) and transducers (RLP00F908) where the + and - low pressure line is constantly supplied with a very small quantity of air, because the pressure signals in the lower measuring range are falsified and the positioning time of... s (RLP00F) is not achieved. dditional information Fitting instructions RLP00F9 M 5058 RLP00F98 M 505 RLP00F90 M 505089 technical manual 7 000 00 Description of operation square root transducer converts the pressure difference (.4...0 Pa) produced at an orifice plate or pitot tube into a standard signal (0...0 bar) that is linear to the flow. he pressure difference of the setpoint range ( = 0.7...8) is set using the adjuster. he integral controller compensates for the control deviations with no persistent error. RLP00F9: he command variable w shifts the volume flow (e.g. SP 80 B temperature controller). n external setpoint signal can be supplied via connection 8 and limited with the adjusters m min and m max. When the connection is open m min is effective, and when it is closed m max applies. RLP00F98: he command variables w (heating) and w (cooling) shift the volume flow (e.g. SSP 80 temperature controller). he volume flows for heating and cooling can be individually limited using the m min and m max adjusters and the internal adjuster m max (int.). RLP00F90: he command variable w shifts the heating volume flow (e.g. SP 80 B temperature controller). he ratio of hot to cold air is fixed at :. n external setpoint signal can be supplied via connection 8 and limited with the adjusters m min and mmax. When the connection is open m min is effective, and when it is closed m max applies. ntended use his product is only suitable for the purpose intended by the manufacturer, as described in the Description of operation section. ll related product regulations must also be adhered to.

l/h l/h 0,... bar Product data sheet 7. 7.440 ngineering and fitting notes Crosswise mounting is not permitted. o prevent turbulent flow causing vibrations that affect the low pressure signal, there must be a smoothing sector in front of the cross meter for measuring the differential pressure. Where there are unfavourable inflows bends, elbows or branches immediately in front of the cross meter a restrictor (accessory 0977 or 07457) must be installed in the plastic hose of the + and connection to attenuate turbulent low pressure signals.
