Double flange level transmitter failure causes and elimination methods

Lianyungang, jiangsu huaxia chemical plant with a liquid level measuring tower rosemount double flange of the thermometer ( Also called double flange level transmitter) , when the equipment after shutdown, there is no level indicator reflects on principle. Thermometer and the pressure of the tower is zero, but still have 85% of the amount of liquid level range, but also the fluctuations, but the technical operators is a little bit confused, immediately contact our manufacturer to after-sales department?

again after we communicate with customers, according to the following four phenomenon analysis it is concluded that one of the a: J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

a, output does not accord with the actual J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

b, the output change slowly lag J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

c, output indicates a value does not change J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

d, output, indicating maximum J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

' Failure theoretical reason and elimination method 】 Magnetic flap | | glass thermometer thermometer: J5T floating ball | | glass thermometer thermometer two-color thermometer

a, transmitter drift; B, medium density change, lead to changes in range; C, fluctuation pressure points is unobstructed J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

a, transmitter aging or transmitter bad; B, range is too big; C, top and bottom pressure points impassability J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

a, process caused by reason; B, fluctuation pressure points impassability. C, transducer fault J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

a, transmitter lock itself, again when the power is on electricity; B, safety gate J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

the reasons: J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

1, equipment downtime is not equal to the tower kettle without material, it is possible. J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

2, and now that the use of double flange thermometer shows that material viscosity may be higher, could form attachments, in front of the diaphragm effect instructions. So if the high viscosity does not recommend the use of double flange thermometer, magnetic flap thermometer. Can use ultrasonic thermometer thermometer or radar J5T magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

3, level still fluctuated because tower kettle is not stationary state, ( Heating or cooling) Can produce fluctuations. Magnetic flap | | glass thermometer thermometer J5T floating ball | | glass thermometer thermometer two-color thermometer

4, if the tower with air ( Pipeline convulsions, the heat convection) Will also impact on instrument. So shutdown after double flange thermometer have instructions fluctuations, is not necessarily the table is broken, is the best way to tear open come down to examine, the next stop is experienced.
