Magnetrol® Instruments With SIL Certification: Protecting Your Plant

In the process control industries, safety and reliability are paramount. Operators are searching for the peace of mind that comes from high-quality instruments. To minimize risks, the Safety Integrity Levels, or SIL, were developed as an integral part of a comprehensive safety system. SIL certification and SIL ratings guarantee a level of dependability and security that operators can trust.


Many Magnetrol® products are SIL-suitable. Below is some more information about the transmitters and switches that are SIL-Suitable or have received SIL certification:

SIL-Suitable Switches

Echotel® Model 961 Single Point Ultrasonic Level Switches
Reliable single point level measurement. Advanced self-testing continuously monitors the electronics, transducer and piezoelectric crystals. An adjustable time delay is provided for reliable measurement in turbulent processes. Rated SIL 2 FMEDA.

ECHOTEL Model 962 Dual Point Ultrasonic Level Switches
Reliable dual point level measurement or pump control. A tip sensitive lower gap allows measurement to within 1⁄4″ of the vessel bottom. The flow-through upper gap allows up to a 125″ (318 cm) separation between switch points. Rated SIL 2 FMEDA.

Single-stage External Cage Float Level Switches
Field-proven switches. Self-contained units designed for external mounting on the side of a vessel, tank or bridle. Over 30 models of mechanical switches have proven their reliability and repeatability for decades in numerous applications. Rated SIL 2 FMEDA.

Single-stage Displacer Level Switches
Ideal for sumps, storage and process vessels. Models A10, A15 and External Caged Displacer Switches offer flexibility in application and are not affected by dirty liquids, coating foam, turbulence or agitation. Rated SIL 2 FMEDA.

Thermatel® TD Series Flow, Level Interface Switches
Reliable operation for flow, level, or interface detection. Offer continuous self-diagnostics. Temperature compensation provides repeatable switch operation with varying process temperature. Gas or liquid flow applications. Rated SIL 1 FMEDA.

THERMATEL TG Series Flow, Level Interface Switches
Suitable for liquid or gas flow, level, or interface detection. Provide a two-wire intrinsically safe circuit between the probe and remote DIN rail enclosure. 24 VDC input power, relay plus mA signal for flow trending/indication. Rated SIL 1 FMEDA.

SIL-Certified Transmitters

Eclipse® Model 706 Guided Wave Radar Level Transmitter
The leader in high-performance guided wave radar. This 24 VDC loop-powered transmitter utilizes a variety of coaxial, twin, and single-rod probes. Performance is not process dependent, and it is capable of measuring low dielectric liquids or solids. Rated SIL 2/3 Certified.

ECLIPSE Model 705 Guided Wave Radar Level Transmitter
Provides measurement performance well beyond that of many traditional technologies. This 24 VDC loop-powered transmitter utilizes coaxial, twin, and single-rod probes. Performance is not process dependent. Rated SIL 2/3 Certified.

E3 Modulevel® Displacer Level Transmitter
Takes displacer transmitters to the next level. Set up in as few as two steps without level movement. Microprocessor-based, HART, AMS and PACTware™ compatible, E3 offers stable, reliable 4-20 mA output in most applications. Rated SIL 2 FMEDA.

SIL-Suitable Transmitters

Jupiter® Magnetostrictive Level Transmitter
Available in single and dual float models. A loop-powered level transmitter with HART communications, PACTware™ DTM interface, LCD display and push button configuration. It may be externally mounted to a MLI or directly into a vessel. Rated SIL 2 FMEDA.

TA2 Thermal Mass Flow Meter
Provides reliable flow measurement of air and gases. Delivers excellent low flow sensitivity, high turndown and low pressure drop. Pre-calibrated and configured for the user’s application. Integral or remote electronics. Rated SIL 1 FMEDA.
