SIL Certified Safety Manual
for E3 Modulevel
®
Model E3X-XXXX-SXX
Liquid Level
Displacer Transmitter
This manual complements and is intended to be used with the
Magnetrol
®
E3 Mod ulevel
®
Liquid Level Displacer Transmitter
Installation and Operating manual (Bulletin 48-635).
Safety Function
The HART
®
version of the E3 Modulevel
®
transmitter will
measure level and transmit a signal proportional to that level
within the stated safety accuracy of ±2% of span (or the
measured error published in I/O Manual 48-635, whichever
is greater). In addition, when continuous, automatic diagnos-
tics detect that the transmitter cannot perform this function,
the output will be driven to the customer-specified out-of-
range signal (i.e., 3.6 mA or 21 mA).
The E3 MODULEVEL is certified for use in low demand
level measurement applications.
Application
The HART
®
version of the E3 MODULEVEL level trans-
mitter can be applied in most process or storage vessels, bri-
dles, and bypass chambers up to the transmitter’s rated tem-
perature and pressure. The E3 MODULEVEL can be used
in liquids, clean or dirty, light hydrocarbons to heavy acids
(SG=0.23 to 2.20) to meet the safety system requirements of
IEC 61508 (Edition 2.0, 2010).
