Min. and Max. recorded temperature
(Menu C1.5.1 / C1.5.2)
Stores the minimum and maximum value for the
temperature occurring during sensor operating time.
application Problems that May indicate
errors in the Signal Converter
•
An improperly closed shut-off valve during zero
calibration results in high calibration values
•
Air/gas bubbles result in high energy levels and high
calibration values
•
Product deposits on the inside of the measuring tube
lead to higher/lower density indications and high
calibration values

Common errors
(with Corresponding Symptoms)
•
Slightly eroded or corroded measuring tube
- Erroneous density measurement
- High frequency
- Measurement error at low mass flow
•
Eroded or corroded measuring tube (product in the
housing)
- Measuring tube does not start
- Low resistance to earth with conducting product
•
Open circuits of drive and sensor coils or resistance
thermometers (RTD)
- Can be measured with ohmmeter
