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.
