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).

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.
