Product Detail


Quick Overview


Order Length: 18 to 216 in (457 to 5486 mm)

The Level Plus® Model MC420 level transmitter satisfies the demand for an economical analog communication interface offering for hazardous area applications. The Model MC420 provides a single-channel analog 4 to 20 mA output for either a product level or an interface level measurement depending on the application and the selected float. The Model MC420 transmitter is approved by FM, CSA, NEPSI, and ATEX for use in Intrinsically Safe applications. Appropriate barriers are required when installing the Model MC420 transmitter in hazardous areas.

In addition to the single-channel 4 to 20 mA loop, the Model MC420 transmitter provides the HART® field communications protocol for setup and calibration. Calibration can also be accomplished using integrated reed switches and a supplied magnet without the need for expensive electronics. Once the transmitter is installed and calibrated there is no requirement for scheduled maintenance or recalibration. Set it and forget it!

The Model MC420 transmitter is available in set lengths from 457 mm (18 in.) to 5486 mm (216 in.) and can be installed in applications with process temperatures between -40 °C (-40 °F) to 125 °C (257 °F). The electronics are permanently sealed in a NEMA Type 4X rated housing made of 316L stainless steel that provides protection against corrosion and resistance to harsh process conditions.
