  • Ordering information
UHC series magnetic float level transmitter and UQC series magnetic ball float level transmitter are composed of body part and local indicator. UHC series magnetic float level transmitter is mounted and connected on the side of vessels. When the float moves up and down with the level (interface) changing, the magnet steel inside float drives the magnetic flakes inside of the indicator to roll over. All the magnetic flakes are coated with red one side and white another side (liquid is red, air is white). The continuous red or white zone can clearly indicate actual level or interface inside of vessels. While UQC series magnetic ball float level transmitter is mounted on the top of vessels. With the level or interface changing, the ball float will move up and down and drive the magnetic connecting rod going up and down. The magnet steel inside of the connecting rod drives the magnetic flakes inside of the indicator to roll over. All the magnetic flakes are coated with red one side and white another side (liquid is red, air is white). The continuous red or white zone can clearly indicate actual level or interface inside of vessels. If equip with remote transducer and upper/lower alarms, the UHC, UQC series transmitters can realize remotely transmitting the level signal and automatically controlling.

UHC, UQC Series Magnetic Float Level Transmitter
2.  Remote unit
Remote transmitter is divided into two forms, one is reed-resistance remote level transmitter, and the other is magnetostrictive remote level transmitter.
2.1 Reed-resistance remote level transmitter
Remote transmitter is binded on outside of chamber. When float moves up and down with level changes, reed switch corresponding to level will pull in under the action of float magnetic field, so that resistance and current will change, transduction circuit will be transferred into signal of 4-20mA DC to realize remoting.
Range: 300mm-6000mm (increasing the range can be manufactured specially)
Power supply: 24V DC
Output signal: DC 4mA-20mA
Ambient temperature: -40℃ - +80℃
Operating temperature: -40℃ - +120℃
Measuring accuracy: ±5mm
Power supply inlet: M20 x 1.5 (female thread) or on request
Explosion-proof: ExdⅡCT4-T6, ExiaⅡCT4-T6
               Protection class: IP67
                2.2 Magnetostrictive remote level transmitter
             Remote transmitter is binded on outside of chamber. There is a magnetostrictive line in remote measuring pipe. Through sensor circuit which is controlled by microprocessor, the equipment launches current pulse along magnetostrictive line, thereby, generates toroidal magnetic field around magnetostrictive line. The magnetic steel inside of float magnetize magnetostrictive line along axial direction. Stacking place of two magnetic fields will generate a reverse pulse, this pulse will transmit to top of sensor along magnetostrictive line, the transmitting time of pulse will be captured and calculated by circuit unit to get the position of float.
Range: 300mm-6000mm (increasing the range can be manufactured specially)
Power supply: 24V DC
