MDT4X2F Series Pressure Sensors With SIL2 SIL2 and PL‘c’ rating with local and remote rezeroing capability Features ■ Simple unshielded two-wire cable connection in high noise ■ Efficient rezero adjustments can be made locally or remotely to the sensor ■ 4-20 mA two-wire signal output ■ Installation for media temperatures up to 400°C ■ Adjustable zero and span, via side-mounted pots ■ Flexible capillary connection between stem with diaphragm and housing ■ 3rd-party agency analysis (exida™) and self-certified based on FMEDA analysis and internal audit ■ Meets Performance Level ‘c’ as defined by the Machinery Directive (Category 1) ■ Meets the following compliance directives, when properly installed and used: SIL2 & Machinery Directive EN ISO 13849-1 From lab to production, providing a window into the process Description The MDT4X2F Pressure Sensor Series provides special features for critical field applications in high noise surroundings. The utilization of unshielded cables is possible for long distance transmission free of noise interference for the converted process pressure signal 4-20 mA. The MDT4X2F comes equipped with adjustable zero and span side-mounted potentiometers. MDT4X2F 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 4-20 mA output signal is rated PL‘c’ as described in the Machinery Directive EN ISO 13849-1. The MDT4X2F Series mA sensors are selfcertified based on the evaluation reports of the respected third-party agency, exida™. The MDT4X2F 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. Additional safety compliance is available by adding a PL‘c’ / SIL2 rated relay that can be threshold activated to put a machine into a safe condition, as described in the Machinery Directive EN ISO 13849-1.
