Thermal Insertion Probe Model 62-9/9500
With Integral Microprocessor Electronics
A uniquely designed microprocessor controlled electronics provides integral local control and display in an explosion proof housing. Optional Remote Mounting of the electronics to a distance of 4000ft provides additional versatility depending on the application.
Flow signal linearity and temperature effects, determined at calibration, are corrected by the microprocessor using operating parameter data stored in EEPROM memory.
How it works
It's really very simple.
Our Thermal Mass Flow Meters operate using a constant temperature system that employs two RTD sensors; one for sensing temperature, and one for sensing flow.
The sensor is heated to a precise temperature above that of the fluid passing by. The fluid conducts heat off the sensor in direct proportion to the mass flow rate.
The temperature is used to set the heat on the flow sensor and correct for changes in the fluid temperature.
