0297762 001: Can be plugged into soft plastic hose, inner Ø 4 mm. If attenuation is insufficient, instead of the
Ø 0.8 mm restrictor, the Ø 0.5 mm restrictor can be used (accessory 0274571; this restrictor is not suitable for
RLP100F908, F914, F123).
0274571 000: Can be plugged into soft plastic hose, inner Ø 4 mm. Suitable for extreme cases when the Ø
0.8 mm restrictor (accessory 0297762) does not provide sufficient attenuation. Not suitable for volume flow
controllers (RLP100F914, F123) and transducers (RLP100F908) 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 1...2 s (RLP100F123) is not achieved.

Description of operation
A square root transducer converts the pressure difference (6.4...160 Pa) produced at an orifice plate
or pitot tube into a standard signal (0.2...1.0 bar) that is linear to the flow. The pressure difference of
the setpoint range (E = 0.7...1.8) is set using the adjuster E. The integral controller compensates for
the control deviations with no persistent error.
RLP100F916:
The command variable w shifts the volume flow (e.g. TSP 80 B temperature controller). An external
setpoint signal can be supplied via connection 8 and limited with the adjusters mmin and mmax. When
the connection is open mmin is effective, and when it is closed mmax applies.
RLP100F918:
The command variables w1 (heating) and w2 (cooling) shift the volume flow (e.g. TSSP 80 temperature controller). The volume flows for heating and cooling can be individually limited using the mmin
and mmax adjusters and the internal adjuster mmax (int.).
RLP100F910:
The command variable w shifts the heating volume flow (e.g. TSP 80 B temperature controller). The
ratio of hot to cold air is fixed at 1:2. An external setpoint signal can be supplied via connection 8 and
limited with the adjusters mmin and mmax. When the connection is open mmin is effective, and when it is
closed mmax applies.
Intended use
This product is only suitable for the purpose intended by the manufacturer, as described in the “Description of operation” section.
All related product documents must also be adhered to. Changing or converting the product is not admissible.

Product data sheet

To 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 0297762 or 0274571) must be installed in the plastic hose of the + and
– connection to attenuate turbulent low pressure signals.
Disposal
When disposing of the product, observe the currently applicable local laws.

this product.
