Principle
The Jupiter JM4 magnetostrictive level transmitter is a loop-powered 24 VDC liquid-level transmitter and is available as a direct insertion transmitter or as an external mounted transmitter onto a Magnetic Level Indicator. It relies on the position of a magnetic float which is designed precisely for the liquid to be measured. This high-accuracy device can be designed for liquid level and/or liquid-liquid interface measurement.
Technology of JM4 magnetostrictive level transmitter
Magnetostriction
A low-energy pulse, generated by the JUPITER electronics, travels the length of the magnetostrictive wire. A return signal is generated from the precise location where the magnetic field of a float intersects the wire. A timer precisely measures the elapsed time between the generation of the pulse and the return of the acoustic signal. Each cycle occurs ten times per second, providing real-time and highly accurate level data.
How magnetostriction works
- LOW-VOLTAGE PULSE
On-board electronics send a low-voltage electrical pulse down the magnetostrictive wire at the speed of light, ten times per second.
- MAGNETS
Magnets contained within the float focus their energy toward the wire at the precise location of the liquid level.
- PIEZOELECTRIC CRYSTALS
The mechanical wave is converted back into electrical energy by two piezoelectric crystals. The on-board electronics interpret the time-of-flight data and indicate the position of the float magnets.
- TWIST
Interaction between the magnetic field, electrical pulse, and magnetostrictive wire cause a slight mechanical disturbance in the wire that travels back up the probe at the speed of sound.
