DIN rail mount temperature transmitter 5437A

thermocoupleRTDresistance

2-wire HART 7 temperature transmitter • RTD, TC, potentiometer, linear resistance and bipolar mV input • Single or true dual inputs with sensor redundancy and drift detection • Wide ambient operating temperature of -50 to +85°C • Total accuracy from 0.014% • 2.5 kVAC galvanic isolation • Full assessment to IEC61508 : 2010 for use in SIL 2/3 applications Application • Temperature measurement of a wide range of TC and RTD types. • Conversion of wide span linear resistance and potentiometer inputs. • Conversion of bipolar mV signals to 4...20 mA. • Integration into asset management schemes. • Critical applications requiring superior accuracy and/or sensor redundancy and drift detection. Technical characteristics • True dual input transmitter. High density 7-terminal design accepts the widest range of dual input combinations. • Sensor redundancy - output automatically switches to secondary sensor in event of primary sensor failure, maintaining uptime. • Sensor drift detection - alerts when sensor differential exceeds user-defined limits, for maintenance optimization. • Dynamic variable mapping for process data in addition to the primary variable e.g. dual input features such as average, differential and min./max. tracking. • Groundbreaking digital and analog signal accuracy over full input span and ambient conditions. • Extensive sensor matching including Callendar Van Dusen and custom linearizations. • Programmable input limits and runtime metering ensure maximum process traceability and sensor out of range protection. • IEC 61508 : 2010 full assessement up to SIL 3 together with enhanced EMC Functional Safety testing to IEC 61236-3-1.
