Moore Industries STZ dual-input smart HART temperature transmitter

Moore Industries has released the SIL 3-capable STZ functional safety smart HART temperature transmitter family. The STZ is said to be a dependable and accurate temperature transmitter for use in safety instrumented systems where dangerous processes occur. The STZ has been certified by exida after rigorous evaluation to ensure conformance with strict IEC 61508:2010 standards for safety-related applications.

The STZ offers a dual sensor input that reduces process interruptions. Backup and fail-over protection allows either of the sensors or inputs to be designated as the primary measurement, with the secondary input acting as the backup sensor in case of primary sensor failure. The dual sensor input also allows for average and differential measurements along with high-select and low-select options.

The STZ is HART 7 compliant with exception-based reporting and dynamic variable mapping. It is HART and DTM programmable with user-oriented basic configuration for fast and accurate set-up. Utilising the HART DD, it can be configured and interrogated on the 4–20 mA loop via any HART handheld communicator or HART compatible host. To prevent unauthorised or accidental reconfiguration of the STZ while it’s performing its safety function, it has an added security feature to allow users to set HART communication into a read-only or off mode. Users can also program or monitor the transmitter with any FDT-compliant host or program such as PACTware using the STZ DTM.
