Developed with sealing structure fabricated thermocouple, can prevent the cr selective oxidation, also changes with different diameter, diameter of the same type k thermocouple is also due to the difference of structure, the stability of also have very big difference.
when choosing thermocouple, must consider as follows: in view of the conditions of use
1, common genetic, temperature and highest temperature insanity would use atmosphere
2, vibration resistance 'online moisture meter' will be sensors and digital signal processing (DSP) two parts together, using leds digital panel shows the percentage of solid material moisture content directly.
the stability of the thermocouple, due to the use of temperature, atmosphere, different to the same kind of sensors, such as the highest use temperature, k type oxidation reduction etc. Compared with the moisture content of instrument, it has the following features:
1, non-contact measurement, has no effect on transmission line, also don't cause trouble for operation.
2, can be continuous determination of moving and stationary material moisture, especially suitable for on-line monitoring.
3, as well as independent determination of moisture, can also be output signal, are to be recorded, and can automatic feedback control system.
