| TPZ Profibus PA temperature transmitter from Moore Industries features an alphanumeric digital display that shows real-time process status and diagnostic information in user-selectable engineering units. |
Model TPZ Profibus PA temperature transmitter from Moore Industries comes as a ready-to-install assembly with sensor, thermowell, fittings, and enclosure. Device 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. TPZ features 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 diagnostic information, and it can be customized to show the process variable or output in user-selectable engineering units.
Loop-powered (2-wire) transmitter offers a variety of input, output, and operation choices. It sets up from the control room using a standard Profibus PA configuration tool to handle 14 RTD and 9 thermocouple types and direct millivolt and resistance/ potentiometer inputs. TPZ communicates process and diagnostic data over a two-way, 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 degrade performance.
Ready-to-install temperature assemblies include a sensor, thermowell, process fittings, and enclosure combinations for mounting in general-purpose or explosion-proof applications. Complete assemblies can be ordered using one part number. www.miinet.com Moore Industries International Inc.
