PR5437 is programmable, universal, isolated, dual input 2-wire transmitter with HART® (version 5 and 7) communication protocol designed for mounting in sensor head. The transmitter is programmable directly from PC or via HART® communication. No external power supply required for configuration.
* RTD, TC, potentiometer, linear resistance and bipolar mV input
* Single or true dual inputs with sensor redundancy and drift detection
* High accuracy across a wide ambient operating temperature of -50 to +85°C
* 2.5 kVAC galvanic isolation
* Full assessment to IEC61508 : 2010 up to SIL 2/3
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 with runtime metering ensure maximum process traceability and sensor out of range protection
* IEC 61508 : 2010 full certification up to SIL 3 together with enhanced EMC Functional Safety testing to IEC 61236-3-1
* Meets NAMUR NE21, NE43, NE44, NE89 and NE107 compliant diagnostics information
Mounting / Installation
* For DIN form B sensor head mounting
* Configuration via standard HART communication interfaces or by PR 5909 Loop Link
* The 5437D can be mounted in zone 0, 1, 2 and zone 20, 21, 22 including M1 / Class I, Division 1, Groups A, B, C, D
