FS2000H NuTec® 2 Wire Thermal Flow Switch
Flow Switch Summary
The FS2000H Flow Switch delivers a combination of the highest flow
range, accuracy and response time available with any thermal dispersion
switch. It is equally well suited for water, liquid, slurries, air, and
gases. The switch set point is fully field settable. Its unique "flat
face" sensor is designed to be mounted flush to the inner pipe surface
or can be extended into the media.
FS2000H can be used in clean or dirty media and is unaffected by
entrained bubbles or particulates. its no moving parts technology
ensures years of maintenance-free, non-clogging performance and creates
no pressure drop in the system. FS2000H temperature compensation, not
found in lesser switches, ensures highly repeatable switching in actual
field conditions.
Input power can be 24 Vac or Vdc, 100/240 Vac, or loop power where
instrument works off common 4-20 mA current loop. Signal for alarm or
limit trips can be 6A, SPDT relay or transistor output. Rugged NEMA 4X
[IP66] rated enclosure and 316L SS all-welded, sensor element delivers
durable long life.
