Comprehensive grasp the electric contact thermometer, skilled application

on electric contact thermometer, the lower limit alarm device sometimes appear very contradictory movement at the same time, the digital display table, on the lower limit alarm indicator lights flash at the same time. The high and low on both ends of the actual level of although cannot exist at the same time, but it is often occurs in the second table of the phenomenon, especially when the liquid level detection tube just after discharge to open the table, are more likely to appear.

after the discharge of the liquid level detection tube, the actual glass thermometer instructions below the ceiling, 75%) Scale, but high alarm indicator light flash, shows high alarm circuit has formed path at this time. Could be electrode short circuit, or outside the electrode end connection, and test tube shell ( Public power supply) Contact, also may be electrode is outside the dirt, and short-circuit test tube shell; There may be the loop cable grounding phenomenon.

electric contact thermometer fault handling: electric contact thermometer of electricity to produce the phenomenon that is covered by oxide, and with the extension of time, its reliability and sensitivity. That can be used to reduce electrode point current methods to solve, because it makes the electrode adsorption force greatly reduced. Also pointed electrode can be used, because it has a certain self-cleaning ability, so as to prolong the service life of the electrode, increase the reliability of the work. Also can adopt the method of oblique installation, in order to reduce electrode, the lower limit alarm opportunities at the same time, because it has the potential to electrode liquid beads and vessel wall flow liquid bead interlinked probability decreases. Electric contact thermometer often drainage, steam flushing, to reduce the electrode head coverings, make its contact cleaning, make the light on the second table not dark or instructions by accident, only to master the knowledge of the instrument to the integrated use of, can make us to be able to quickly find the problem when dealing with problems.
