Anticorrosive thermocouple prevent interference

Anticorrosion thermocouple resistance to trouble in the way of use: thermocouple in the use of trouble first characterized by: high harmonics, noise and vibration, load matching, fever, and other issues. These trouble is inevitable, because the anticorrosion thermocouple part of thermocouple input rectifier circuit, the output part of inverter circuit, they are made up of the switching effect of nonlinear components, and in the process of open circuit, have higher harmonic, then make the input power and output voltage waveform and current waveform distortion. The following on the harmonic problems are analyzed and corresponding measures are put forward.

reasonable choice of anticorrosion of thermocouple parts rules: the selection of anticorrosive thermocouple, should be in accordance with the accused of the target type, scale, the static speed precision of speed and start torque, etc. To think, to make it in satisfaction process and produce the pleading, also is good, and the economy.

the selection of anticorrosive thermocouple box layout: the layout of boxes of anticorrosive thermocouple corresponds to a condition, must think temperature, humidity, dust, ph value, elements such as corrosive gases. Has the following several common layout: anti-corrosion type ( PP raw material) 。 Itself no chassis, can be installed in the electric cabinet or electric indoor screen, plate, frame, especially for many sets of anticorrosive thermocouple have choose when using, but pleaded with higher environmental conditions. Lined with four fluorine type. Suitable for normal use, can have a few dust or a small amount of temperature and humidity. Seal type IP45 type. Poor environment suitable for the industrial conditions in the field. Steam jacketed type. Suitable for poor environmental conditions, and water, dust and corrosive gas occasions.
