®
Model R96 Installation and Operating manual
( ulletin 58-602 dated January 2015 or later).
Application
The PULSAR Model R96 (HART
transmitter can be applied in most metal and concrete
process or storage vessels. The PULSAR Model R96 can
be used in liquids or slurries to meet the safety system
requirements of IEC 61508/IEC 61511-1.
Benefits
The Magnetrol
Model R96 (HART) transmitter pro-
®
vides the following benefits to your operation:
• Protection up to SIL2 (Safe Failure Fraction = 92.7%)
as independently assessed (hardware assessment) by
exida as per IEC 61508/ IEC 61511-1.
• Antenna designs to +400 °F (+200 °C),
750 psig (51.7 bar)
• IS, XP and Non-Incendive approvals
• Quick connect / disconnect antenna coupling
• Performance not process dependent (changing specific
gravity and dielectric have no effect).
