The Jupiter® Magnetostrictive level transmitter from Orion Instruments® provides a 4-20 mA output, proportional to the level being measured. Jupiter models are designed to attach quickly and easily, via standard clamps, to Orion’s Atlas™ and Gemini™ magnetic level indicators or can be directly inserted into a wide variety of process vessels.
Packaged in an ergonomic dual compartment enclosure, the unit offers many features not found in typical magnetostrictive units today. The dual compartment design allows for separation of wiring and electronics and helps facilitate simple, easy installation and set-up for both top and bottom mount versions.
With a JUPITER Magnetostrictive Transmitter, an Orion MLI offers high accuracy and high linearity at a reasonable price.
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.
Technology of the Enhanced Jupiter® Magnetostrictive Level Transmitters
The Enhanced JUPITER transmitter utilizes the engineering principle of magnetostriction and the effect of a magnetic field on the magnetostrictive wire as the basis for operation of the instrument. The primary components are the probe assembly containing the wire and the electronics assembly.
A low energy pulse which is generated by the electronics travels the length of the magnetostrictive wire. A return signal is generated from the precise location where the magnetic field of the MLI float intersects the wire. A timer precisely measures the elapsed time between the generation of the pulse and the return of the mechanical or acoustic signal. This is detected by the acoustic sensor located below the cast aluminum electronics housing. The software is set up to interpret the time-of-flight data and to display and transmit the process variable data resulting from the measurement.
