The Model T21 Point Level Switchuses a thermal differential technique to measure liquid flow,level or interface by sensing changes in the thermal heat
transfer characteristics of the media wher
The sensor co
Temperature Detectors (RTDs) encased in twin 316
series stainless steel tubes. One RTD is self heated
using a co
unheated and provides an accurate ambient process
temperature reference. The thermal differential
created between the heated and reference RTD
pair is a function o
sensor is in contact. The differential is greatest
when no liquid is present (dry condition) and
decreases as liquid quenches the switch sensors
(wet condition).
