Floating ball after long-term use under condition of high temperature thermometer debugging use and maintenance

Floating ball thermometer debugging, use and maintenance 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer debugging methods 0

1, the transmitter Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

the magnets in the zero level of the liquid level sensor, the sensor of the bottom of the dry reed pipes, adjust & other; Zero & throughout; Potentiometer, make the output of 4 ma. Then put magnets at full & other; Range & throughout; Place, adjust & other; Range & throughout; Potentiometer, make the output to 20 ma, so repeated several times, debugging can be finished. 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

2, by the use for a long time, especially under the condition of high temperature after using for a long time, if discover indicator tube track is ineffective, should first check the link at the top of the magnetic field strength, if already demagnetization, magnetic steel should be changed. 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

3, explosion-proof products, use considerations. 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

( 1) Alarm, selection, installation and maintenance of transmitter, must comply with the law of the People's Republic of China on explosive dangerous location electrical safety regulations provisions. 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

( 2) Junction box inside and outside the ground must be solid and reliable, and grounding resistance should be & le; 2Ω 。 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

( 3) Electrical wiring must clearance and creepage distance & ge; 10mm。 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

( 4) Alarm and open after maintenance must cut off power supply in the transmitter, remove the process, should avoid to damage the explosion-proof surface. After maintenance, lead and table cover must be locked, to prevent slippage. 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

( 5) Explosion-proof surface is painted, should besmear anti-rust oil. The double helix cone mixer 0 Ed magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
