PR 6437 DIN-Rail Temperature Transmitter from PR electronics

The PR 6437 DIN-Rail temperature transmitter supports single or true dual inputs with sensor redundancy and drift detection. Thus, the 6437 Series ensures reliable measurement and improves uptime, even in critical applications. Dual input mapping options allow dynamic reporting of average, differential, minimum/maximum, and other process variables for enhancing control as well as analysis. This DIN-rail temperature transmitter features programmable damping (0-60s) and excellent signal-to-noise performance to deliver stable outputs under varying conditions.

• 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, thus 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, for example: dual input features such as average, differential, and minimum/maximum tracking.
• Groundbreaking digital and analog signal accuracy over full input span as well as ambient conditions.
• Extensive sensor matching including Callendar Van Dusen in addition to custom linearization. 
• Programmable input limits with runtime metering ensure maximum process traceability and also provide 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. 
  
• Meets NAMUR NE21, NE43, NE44, NE89, and NE107 compliant diagnostics information.
• Failure rates for 6437xxSx correspond to Performance Level "d" according to ISO-13849.
