Technical Characteristics
True dual input HART temperature transmitter. The high-density 7-terminal design accepts the widest range of dual input combinations.
Sensor redundancy – output automatically switches to a secondary sensor in the 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.
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 assessment up to SIL 3 together with enhanced EMC Functional Safety testing to IEC 61236-3-1.
