Model MR Sanitary Magnetostrictive Float Level Transmitters

Product Overview

The Level Plus Model MR level transmitter satisfies the demand for an analog communication interface that offers the liquid-level marketplace unsurpassed flexibility to meet most process application conditions. The Level Plus Model MR transmitter provides 3-in-1 measurement using one process opening for product level, interface level, and temperature measurements. Once the transmitter is installed and calibrated there is no requirement for scheduled maintenance or recalibration.

Level Plus Model MR transmitters are modular in design, offering you a selection of electronic housing styles, transmitter pipe styles and wetted materials. The Level Plus Model MR transmitter features a removable sensing element and can also incorporate an RTD for spot temperature measurement. Subject to local electrical codes, the sensing element and electronics housing can be removed from the transmitter pipe without disturbing the operation of your process saving both time and money.

Up to two 4 to 20 mA loops are available for analog indication of level, interface, and/or temperature. HART(R) communication allows the Model MR transmitter to indicate and display all three measurement variables simultaneously. Set-up, calibration, and diagnostics are available from any point in the loop using a standard HART hand-held communicator. An optional on-board display and keypad is also provided for local indication and programming.

Magnetostrictive Principle

Level Plus gauges are based on the magnetostrictive measuring technology, which is successfully used for more than 30 years at MTS. Magnetostriction is a combination of magnetic (non contact) and ultrasonic effects (speed control). According to MTS know-how, two magnetic fields interact, and a torsional strain pulse on the sensor element results. The running time of the the pulse is used to determine the level measurement with a high degree of accuracy and reliability. All Level Plus Tank Gauge systems base on this principle, which ensures a really innovative and promissing measuring system for continous level measurement.
