| Abstract |
The Model T21Point Level Switch uses a thermal
differential technique to measure liquid flow, level
or interface by sensing changes in the thermal heat
transfer characteristics of the media where it is
located. The sensor consists of a pair of matched Resistance
Temperature Detectors (RTDs) encased in twin 316 series
stainless steel tubes. One RTD is self-heated using a constant
DC current. The other sensor is unheated and provides an accurate
ambient process temperature reference. The thermal differential
created between the heated and reference RTD pair ...
