Moore Industries Profibus PA temperature transmitter allows up to 32 field devices

Moore Industries' TPZ PROFIBUS PA Temperature Transmitter saves wire and installation costs by allowing up to 32 field devices (126 with repeaters) to be networked onto one, low-cost PROFIBUS PA data link.  The TPZ features industry-leading 20-bit input resolution to deliver measurement accuracies of up to ±0.05°C (±0.09°F).  A large two-line, alphanumeric digital display shows real-time process status and valuable diagnostic information, and can be customized to show the process variable or the output in user-selectable engineering units.

The loop-powered (2-wire) TPZ offers dozens of input, output and operation choices.  It sets up from the control room using a standard PROFIBUS PA configuration tool to handle 14 RTD types, 9 thermocouple types, as well as direct millivolt and resistance/potentiometer inputs.  The TPZ communicates process and diagnostic data via a two-way, all digital communication protocol ready for direct interface with an AMS, DCS and other computer-based SCADA systems.  Long-term stability allows up to 5 years between scheduled calibrations.  Advanced RFI/EMI protection and ambient temperature compensation guard against environmental factors that can quickly degrade measurement accuracy.

Ready-to-install TPZ temperature assemblies include a sensor, thermowell, process fittings and enclosure combinations for mounting the transmitter in general purpose or explosion-proof applications.  Complete assemblies can be ordered using a single part number.
