The EG Series is a magnetostrictive level transmitter used to accurately measure the changing level of liquids. The EG magnetostrictive level transmitter uses the principles of buoyancy and magnetostriction. Single and two-float designs are available.
EG Series Magnetostrictive Level Transmitter
The EG series is a magnetostrictive level transmitter using buoyancy, magnetostriction and state-of-the-art electronics technologies to accurately measure the level of a wide variety of liquids, including interface and insoluble multiple liquids with a two-float design. In the typical EG series magnetostrictive level transmitter a float, appropriately sized for the specific fluid density, is mounted on the level transmitter stem such that the float will travel up and down due to the buoyancy of the float from the fluid being measured. The float contains a magnetic element. To locate the float position the magentostrictive level transmitter electronics sends a short current pulse down a sensor wire located within the level transmitter stem with a specific frequency, setting up a magnetic field along its entire length. This field interacts immediately with the field generated by the magnet contained within the float. The overall effect is that during the brief time that the current flows, a torsional force is produced in the wire, much like a sonic vibration or wave, and travels back to the magnetostrictive level transmitter electronics. A timing circuit exists within the electronics which measures the time-of-flight (TOF) between the start of the current pulse and the return signal. In this manner the float’s location (and therefore the fluid level) is very precisely determined and presented as a level signal by the magnetostrictive level transmitter, typically 4-20mA.
The JFR Series is a open-air radar level transmitter designed for measuring the changing level of liquids, slurries and bulk solids in tanks, bins and silos. Operating at either 10GHz or 26GHz the JRF series radar level transmitter products will provide non-contact continuous level measurement with high accuracy and reliability.
The ultrasonic level transmitter is a non-contact, low-cost and easy-to-install measuring device. It can be applied to most industrial applications for both solids and liquids. Most important aspect of is that it is easy-to-install and low maintenance due to no moving parts.
EF/MEF Series are by-pass level transmitter product lines, more commonly know as magnetic level gauge devices that can be equipped for local visual indication only or with level switches and an electronic level transmitter output. The magnetic level gauge units include their own self-contained chamber that would be mounted to the vessel, typically via side connections at the top and bottom areas of the EF/MEF by-pass chamber. The EF is standard size and MEF is a smaller “mini” version. These magnetic level gauge units are safer than glass gauges that they typically replace.
