Jerguson® JMT™ Series Magnetostrictive Transmitter

Elevate Accuracy with Magnetostrictive Level Measurement: Precision You Can Count On

The JMT Series magnetostrictive transmitter represents a significant advancement in level measurement technology. The integration of Jerguson’s signal capture technology sets it apart with its superior signal-to-noise ratio, ensuring highly accurate level readings even in challenging environments. The dual-entry enclosure design enhances its functionality by offering both safe and convenient access to the HMI on the front and easy access to power connections in the back. The HMI enhances user interaction by offering instant access to vital information, such as current level readings and device settings, all at the touch of a button. The real-time waveform graph is an especially useful tool for monitoring and diagnostics, offering a visual representation of the process in action.

​

Compatibility with HART 7 makes the JMT highly versatile and easy to integrate into existing systems, facilitating seamless communication and control. The transmitter is also designed with user-friendliness in mind, from installation to setup, ensuring that it can be quickly and efficiently deployed in various applications. In line with Jerguson’s reputation for reliability, the JMT complements our established range of flag indicators, floats, and switches, adding a robust solution for continuous level control.

JMT Method of Operation

The on-board electronic module sends a low-power pulse down the sensing wire of the transmitter. The float, which is designed to reside precisely at the fluid level, contains internal magnets outwardly projecting a strong magnetic field. Where the float’s magnetic field intersects the sensing wire, a torsional return “pulse” results, and travels back towards the electronics, where it is measured. The “time of flight” is used to determine the position of the float.

Mounting Styles

The JMT Magnetostrictive Transmitter can be mounted via direct Insertion into a storage vessel, or externally to a Magnetic Level Gage with a variety of connection types. When installed to the Jerguson Magnicator, the unique magnetic arrangement allows for almost any chamber combination, including Schedule 160, without sacrificing reliability. A highly reliable and accurate means to add continuous level measurement to almost any application.
