Thermal mass wo sensor principles
Order example
Mounting accessories
Symmetric
temperature prole
(a) No ow
In the absence of ow, the heat
from the heater spreads evenly
left and right, so the temperature
distribution is like (a).
(b) Small ow
When ow begins, the inlet side
is cooled by the ow, the outlet
side is warmed by the heat of the
inlet side of the heater, and the
temperature distribution is like (b).
(c) Large ow
When the ow increases, it
becomes a distribution like (C).
Since the temperature distribution
before and after the heater is
proportional to the ow rate, the
ow rate can be determined from
the ratio.

NOTE
*1. In case hysteresis is set at less than or equal to 2 digits, switch output may chatter if input
detected uctuates near the set point.
*2. When using window comparator mode, the difference between two set points must be greater
than the xed hysteresis, otherwise will cause the switch output to malfunction.
