Magnicator® Accessories for High-Temperature Insulation

The removable hot-insulation jacket covers the entire magnetic level gauge. Custom openings provide access to process connections, the indicator, switches and transmitters. Therefore, operators can protect the chamber without limiting access to essential components.

The jacket uses PTFE-coated and impregnated fibreglass for durable thermal protection. Sewn-seam construction creates a secure, custom-fitted assembly for each gauge. Stainless steel grommets add strength around the closure points. In addition, polypropylene and fibreglass drawcords secure both ends.

The standard one-inch jacket supports temperatures up to 500°F (260°C). Higher-temperature requirements require application review. Since operators can remove and reuse the jacket, routine inspection and maintenance remain straightforward.

Cryogenic Insulation with Moisture Protection

Cryogenic insulation helps maintain process temperatures from 32°F (0°C) down to -250°F (-156°C). The system uses two-inch-thick polyisocyanurate foam around the gauge chamber.

A 0.016-inch aluminum jacket provides an external moisture barrier. Sealed joints further limit moisture entry. Consequently, the insulation helps reduce frost and ice buildup on the chamber and enclosed components.

When cryogenic insulation is selected, a non-frost extension is required. Although it is ordered as an optional accessory, the extension moves the indicator away from the insulated chamber. This helps maintain clear level visibility in low-temperature service.

Non-Frost Extensions for Clear Level Indication

The standard non-frost extension uses 2½-inch acrylic construction. It separates the visual indicator from the cold chamber and surrounding insulation.

This Magnicator accessory works with the Wide Indicator and supports custom sizes. Therefore, the extension can accommodate different insulation thicknesses and installation requirements.

Electric Heat Tracing for Temperature Maintenance

Electric heat tracing helps maintain the gauge chamber temperature during cold ambient conditions or heat-sensitive processes. Standard installations use two tracing passes for consistent coverage.

The electric heat trace includes a Class II configuration as standard. An optional Class I, Division 1 configuration supports qualifying hazardous locations. A thermostat can also regulate the maintained temperature.

Available systems include UL-approved NEMA 4 construction. The maximum exposure temperature reaches 375°F, while the maximum maintenance temperature reaches 250°F.

Steam Heat Tracing for Process Heating

Steam heat tracing provides another method for maintaining chamber temperature. The system uses ⅜-inch outside-diameter tubing with ⅜-inch compression fittings at both ends.

A standard installation uses four tracing passes around the chamber. This arrangement distributes heat along the gauge and supports applications with an available steam source.

Magnetic Particle Trap for Ferritic Material

The magnetic particle trap helps prevent ferritic material from collecting around the float magnets. This buildup could interfere with float movement and level indication.

The standard design uses a socket-weld tee in the lower process connection. It includes a ½-inch NPT plug and magnet. Operators can remove the plug and magnet for cleaning after isolating the gauge.

Combination Sight Glass and Magnetic Level Indicator

A combination configuration adds a glass level gauge beside the magnetic level indicator. Operators can use the glass gauge for calibration and level verification.

This option can upgrade existing sight glass installations while reducing routine glass gauge use. However, this configuration does not suit ASME Section I installations.
