Page 9: Start-Up, Operation
Start-Up, Operation Function The METS-WTEx is screwed directly into the process via the process connection. A change in resistance of the sensor element in the tip of the thermowell is transformed into an electrical standard signal by a measuring amplifier. The signal changes proportional to the temperature and can be evaluated. -
