Tester (fixed instrument) common problems and solutions

Sulphur meter (fixed sulfur meter) common problems and treatment methods First, the sulfur content of the electrolytic cell 1, the electrolytic cell leakage leads to air tightness of the gas path.

2. The dirt on the four pole pieces in the electrolytic cell should be cleaned 3. The four pole pieces in the electrolytic cell and the controller should be connected reliably.

Second, the sulfur analyzer stirrer:

The disappearance of the magnetic force of the stir bar is a common cause of stirring out-of-step and should be replaced.

Third, the sulfur measurement instrument temperature control part 1, A, temperature has been displayed in 1999 °C, said the thermocouple circuit is not open or its internal circuit.

B. The temperature does not increase at all times, but there is a heating current, which means that the thermocouple is reversed.

C. The temperature is always at room temperature, indicating that the thermocouple wire is short-circuited.

2, the temperature value is less than the set furnace temperature, there should be heating furnace flow. If the furnace flow shows 0.0A, it means that the insurance tube is bad, and the internal opening of the silicon carbon tube itself or the connection is not connected.

3, temperature fluctuations are too large, generally the reason for the silicon carbon tube. The resistance value should be 7~~8Ω.

Fourth, sulfur measuring instrument gas path airtightness decreased:

Flowmeter indication should be between 0.8~~1.2. If the airtightness is reduced, the following components should be inspected: air pump, flow meter, glass tube, rubber tube and air connection.
