5437D2, 2-wire HART 7 Temperature Transmitter, Dual Input Features : RTD, TC, potentiometer, linear resistance and bipolar mV input 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 Application Temperature measurement of a wide range of TC and RTD types
Configuration via standard HART communication interfaces or by PR 5909 Loop Link
Conversion of bipolar mV signals to 4...20 mA
Conversion of wide span linear resistance and potentiometer inputs
Critical applications requiring superior accuracy and/or sensor redundancy and drift detection
Dynamic variable mapping for process data in addition to the primary variable e.g
Extensive sensor matching including Callendar Van Dusen and custom linearizations
Groundbreaking digital and analog signal accuracy over full input span and ambient conditions
High density 7-terminal design accepts the widest range of dual input combinations
Integration into asset management schemes
Meets NAMUR NE21, NE43, NE44, NE89, NE95 and NE107 compliant diagnostics information
Mounting / installation For DIN form B sensor head mounting
Programmable input limits with runtime metering ensure maximum process traceability and sensor out of range protection.
Sensor drift detection - alerts when sensor differential exceeds user-defined limits, for maintenance optimization
Sensor redundancy - output automatically switches to secondary sensor in event of primary sensor failure, maintaining uptime
