AMETEK Jupiter - Model JM4 -Magnetostrictive Level Transmitter
The Jupiter JM4 liquid 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. The high safety level of JUPITER is demonstrated by a Safe Failure Fraction > 90 %.
- 4-button user interface and graphical LCD display provide enhanced depth of data, indicating on-screen waveforms and troubleshooting tips.
- 4-20 mA output
- Rotatable housing can be dismantled without depressurising the vessel via “Quick connect/disconnect” probe coupling.
- Ergonomic dual compartment enclosure
- Simple set-up and configuration
- Smart Probe Technology
- Easy attachment to an MLI
- Direct insertion for a wide variety of vessels and applications
Jupiter operates on the Time-of-Flight principle. A low energy pulse, initiated by the transmitter electronics, travels the length of the magnetostrictive wire 10 times per second. A return signal is generated from the precise location where the magnetic field of a float intersects the wire, resulting in a mechanical wave response. A timer precisely measures the elapsed time from the generation of the pulse and the moment each return wave is captured by a piezoelectric sensor.
