E-T-A
extends product range of flow monitors
Major
features of the compact single-point flow switch are its optimised design
for the special applications, the push-in monitoring head and the wide
temperature range which makes it suitable for use in ambient temperatures
from -25 to +100 degrees centigrade. The integral electronic control unit
in the stainless steel monitoring head saves space. Electrical connection
is by means of a 3-pole M12 connector to IEC 947. The required supply
voltage is DC 24V. The
FS20 allows monitoring of either a maximum or minimum limit value. The
desired switch point may be adjusted steplessly by the user depending on
the medium via a potentiometer. A short-circuit proof switching output
provides signalisation with a power Mosfet. Power failure, e.g. in the
event of wire breakage, will be signalled like a flow fault. Method
of operation of the E-T-A Flow Switches type FS20 is the calorimetric
principle. The invasive measurement implies no moving parts in the flow
stream and no wear, keeping the equipment maintenance-free; impairment of
the medium is excluded. E-T-A

E-T-A’s
range of flow monitors and meters are suitable for widespread applications
ranging from the chemical industry over industrial engineering up to
process control in cooling equipment. Monitored media are water and watery
liquids, oils, air and gases, even with high pressure values. The Flow
Switch FS20 is a further extension of the flow monitor range of E-T-A for
applications in pipes with big diameters as well as in cooling equipment
with thick-walled insulation.
