Description
The PR 6437D, from PR electronics, is an intrinsically safe, HART 7 temperature transmitter with multiple hazardous area approvals. It features programmable input limits with runtime metering to ensure maximum process traceability and sensor out of range protection.
- RTD, thermocouple (TC), potentiometer, linear resistance, and bipolar mV input
- wide ambient operating temperature of -50 to 85°C (-58 to 185˚F)
- total accuracy from 0.014% 2.5 kVAC galvanic isolation
- full assessment to IEC61508 : 2010 for use in SIL 2/3 applications
Features of this Industrial Temperature Transmitter
- True Dual Input Transmitter – 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 minimum / maximum tracking
- Digital and Analog Signal – groundbreaking accuracy over full input span and ambient conditions
- Extensive Sensor Matching including Callendar Van Dusen and custom linearization
- Programmable Input Limits with runtime metering ensure maximum process traceability and sensor out of range protection
- IEC 61508 : 2010 – full assessment up to SIL 3 together with enhanced EMC Functional Safety testing to IEC 61236-3-1
- NAMUR Compliant – meets NE21, NE43, NE44, NE89 and NE107 compliant diagnostics information
- available in models that are suitable for the use in systems up to Performance Level “d” according to ISO-13849
Easy, Flexible Mounting
- DIN rail mounting with up to 84 inputs per meter
- configuration via PReset software using PR5909 Loop Link / HART modem, or by asset management tool (e.g. Pactware, AMS, HART communicator)
- the 6437D can be mounted in zone 0, 1, 2 and zone 21, 22 including M1 / Class I, Division 1, Groups A, B, C, D
Common Uses of the 6437D Temperature Transmitter from PR electronics
