Moore Industries THZ3 dual input HART temperature transmitter with IS inputs

Moore Industries has expanded its Associated Intrinsically Safe (AIS) range of products with the release of the THZ³ compact dual input smart HART temperature transmitter in DIN rail mount housing with AIS sensor connections. The intrinsically safe AIS option allows direct connection of sensors located in hazardous areas since it includes an internal intrinsically safe barrier in the front end of the THZ³.

The THZ³-DIN with the -AIS option is an associated apparatus suitable for mounting in non-hazardous or Class I, Division 2/Zone 2 hazardous locations with sensor input terminals connected to equipment or sensors located in Class I, II, III, Division 1/Zone 0/1 hazardous locations. Installation costs are reduced since the intrinsically safe barrier is embedded in the receiving device. There is no need for the additional cost of the IS barrier, cabinet space, high-integrity clean ground connection, separate power supply or custom vendor backplanes. This drastically reduces the cost of purchasing, installation and maintenance versus more traditional approaches requiring a separate Zener or isolating barrier. Blue connectors on the THZ³-DIN with -AIS option provide a visual way to recognise the AIS capability.

The dual-input THZ³-DIN with the -AIS option offers HART 7 compliance, 20-bit resolution, sensor failover and backup capability, device intelligence including sensor drift and corrosion detection, and an input simulation capability. It is HART configurable via any HART handheld configurator or HART compatible host. Users can also program or monitor with any FDT compliant host or program, such as PACTware, utilising Moore’s DTM.
