Meets the following
compliance directives, when properlyinstalled and used:– SIL2–Machinery
Directive EN ISO 13849-1 The PT46X4 Series
pressure sensor is a ±0.5% sensor ideal for general melt pressure measurements
requiring simple installation, repeatability and reliability. The PT46x4 sensor
provides the industry standard 4-20 mA amplified signal designed to work with
DCS and PLCs. The PT46X4 comes equipped with adjustable zero and span
side-mounted potentiometers. PT46X4 Series mA sensors can be rezeroed in two ways:
locally via the zero potentiometer, or remotely via shorting two pins together
(contact closure). Optional thermocouple or RTD configurations are available to
provide melt temperature. The PT46X4 features a 1/2-20 UNF thread for simple
and easy installation in standard transducer mounting holes. The 4-20 mA output
signal is rated PL‘c’ as described in the Machinery Directive EN ISO 13849-1.
The PT46X4 Series mA sensors are self-certified based on the evaluation reports
of the respected third-party agency, exida™. The PT46X4 Series mA sensors have
undergone extensive FMEDA analysis (Failure Mode Effects and Diagnostic
Analysis). The FMEDA reports show that these sensors have been evaluated for
random failure requirements and meet Performance Level ‘c’ (PL‘c’) as well as
SIL2 (Safety Integrity Level 2). The information in the FMEDA report can be
used by the customer’s system designer as part of the overall qualification of
the device in the system for PL‘c’ or SIL compliance. The PT46X4 Series can be
equipped with a safety relay, separate from the signal output. Called Guardian,
this optional relay signal has an application specific pressure threshold
setting that will place a machine in a safe mode as described in the Machinery
Directive EN ISO 13849-1. The

Series includes models PT4604, PT4624, PT4634, TPT4604, TPT4624, and
TPT4634.
