measuring probe
Small temperature differences in shut-off pipes and ducts can cause minimal flows. Even these would
be detected and measured by the EE75. The resulting fluctuations in the output signal can be suppressed
by the low flow cut-off. Cut-off point and switching hysteresis can be specified using the configuration
software.
Low flow cut-off
The EE75 measures air velocity in m/s or ft/min. The configuration software can be used to enter the cross-
section. This enables the transmitter to calculate the volumetric flow rate in m³/min or ft³/min. The data can
be displayed and directed to one of the analogue outputs.

The innovative design of the probe head
minimises the effect of the angle of
inflow on the measuring result. The
deviation of the measuring value remains
< 3% up to an angle of inflow (α) of ± 20°
between the direction of inflow and the
sensor element's longitudinal axis.
