The PT46X4 Seriespressure sensor is a ±0.5% sensor ideal for general melt pressure measurementsrequiring simple installation, repeatability and reliability. The PT46x4 sensorprovides the industry standard 4-20 mA amplified signal designed to work withDCS and PLCs. The PT46X4 comes equipped with adjustable zero and spanside-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 toprovide melt temperature. The PT46X4 features a 1/2-20 UNF thread for simpleand easy installation in standard transducer mounting holes. The 4-20 mA outputsignal 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 reportsof the respected third-party agency, exida™. The PT46X4 Series mA sensors haveundergone extensive FMEDA analysis (Failure Mode Effects and DiagnosticAnalysis). The FMEDA reports show that these sensors have been evaluated forrandom failure requirements and meet Performance Level ‘c’ (PL‘c’) as well asSIL2 (Safety Integrity Level 2). The information in the FMEDA report can beused by the customer’s system designer as part of the overall qualification ofthe device in the system for PL‘c’ or SIL compliance. The PT46X4 Series can beequipped with a safety relay, separate from the signal output. Called Guardian,this optional relay signal has an application specific pressure thresholdsetting that will place a machine in a safe mode as described in the MachineryDirective EN ISO 13849-1.
