Magnetic flap thermocouple installation considerations

1. Should be taken before using the correction magnets will below zero ball into a red, the other ball into a white;

　　2. If the users to use with heat pipe road, must choose non magnetic materials, such as copper tube, etc. Heating temperature according to the medium conditions;

　　3. Magnetic flap thermocouple installation position, should avoid or away from the material medium import and export, avoid the material fluid local area of rapid change, influencing the accuracy of the level measurement;

　　4. Media should not solid impurities or magnetic materials, lest cause jam to float;

5, magnetic frame around the thermocouple ontology does not allow a permeable material close to disable fixed wire, otherwise it will affect the normal work of the magnetic flap thermocouple.

　　6. Open the bottom flange, into the magnetic float ( Note: magnetic end up heavy end, cannot flip. ) ；

　　7. Debugging should open the upper guide tube valve, then slowly open the bottom valve, let medium smoothly into led tube, observe whether magnetic turn red and white ball is normal, then close the tube valve, open the drain valve, let the dominant tube liquid level drops, this method for three times, it is normal, can be put into operation;

　　8. Should according to the situation of medium, not regular cleaning dominant remove impurities;

　　9. For more than a certain length ( Ordinary > 3 m, anti-corrosion type > 2 m) The thermocouple, need to increase the middle flange reinforcement or ear soar as a fixed support, to increase the strength and overcome its weight;

　　10. Magnetic flap thermocouple installation must be perpendicular to the magnetic flap between thermocouple and container tube should be equipped with ball valve, easy to maintenance and cleaning;

　　11. When equipped with remote transmission meter to do the following several: a) Should make remote meter close to the thermocouple led tube, and stainless steel hoop fixed ( Disable the iron) ； b) Far eastone meter on induction surface should be oriented and close to the leading tube; c) Far eastone meter should be zero and thermocouple zero indicator at the same level; d) Far eastone matching between the instrument and display instrument or industrial attachment had better wear protection pipe laying alone or in combination with block 2 core cable laying; e) Junction box into the line hole laying, require good seal, so as to avoid the rain, moisture intrusion and make the remote transmission meter does not work, after the completion of the junction box in maintenance or commissioning should be covered in a timely manner.

magnetic flap thermocouple installed on the tank for the lateral extension tube, the inside of the tank liquid level can be informed by indicator turning clear. The bypass pipe outside can be equipped with magnetic switch, as electrical contact signal output, or liquid level transmitter for remote level signal transmission and control level. The thermocouple is a reliable safety instrument. Because of the magnetic coupling isolator airtight structure. Particularly applicable to flammable, explosive and toxic corrosion liquid level detection. So that the original complex environment of liquid level detection means become simple and reliable safety. Thermocouple with local display direct reading type characteristics.
