Jupiter® Model JM4: Next Generation Magnetostrictive Level Transmitter

The Jupiter JM4 Magnetostrictive level transmitter from Orion Instruments is the newest and most advanced level instrument to date. The JM4 is available as a direct insertion option, as well as an external mount on any Orion magnetic level indicator (MLI) or modular instrumentation bridle. With an improved design, unparalleled performance, and a collection of new and innovative features, the JM4 provides safer, simpler, and smarter measurement in total and interface level applications.

Leading Edge Hardware and Software

The JM4 is engineered to be the smartest, most innovative magnetostrictive transmitter available. To this end, numerous enhancements have been introduced, including greater signal-to-noise ratio (SNR), a full graphic local user interface, HART 7.0 (Foundation fieldbus available), local waveform capture, and a more intuitive device type manager (DTM) allowing for remote configuration, trending, and diagnostics.

Field Rotatable and Removable Transmitter Head

The JM4 is the first magnetostrictive transmitter in the industry to offer a field-removable and rotatable head. The removable head allows for simpler transmitter maintenance and troubleshooting without disrupting the process. 310° of head rotation provides users with greater accessibility to operate the JM4s on-board graphical interface.

Smart Probe

To further enhance the removable head, the Jupiter Model JM4 also features Smart Probe technology. When any JM4 transmitter head is attached to a probe, a single push of a button imports factory settings into the head, and in seconds, the transmitter is ready for operation.

Remote Mount Option

Jupiter now offers a remote mount option. Available in 3 and 12 ft lengths, the transmitter head is attached to the probe via a flexible cable to allow for easier viewing under spacial constraints.

Measurement Principle

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 Jupiter® Model JM4 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.
