Profibus PA brings temperature sensors
together
A Profibus PA temperature transmitter saves wire and installation costs by allowing up to 32 field devices to be networked onto one, low-cost Profibus PA datalink.
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 datalink The TPZ features industry-leading 20bit input resolution to deliver measurement accuracies of up to +/-0.05C

System provides secure wireless connectivity
Moore Industries' WLM employs frequency hopping spread spectrum technology and 32-bit CRC error correction for secure, robust communications.
Flexible sensors save time and money
The Worm sensor slides through the enclosure's entry port, and snaps into place without removal of the enclosure, rigid conduit, connection head or any assembly components.
A large two-line, alphanumeric digital display shows real-time process status and valuable diagnostic information, and can be customised to show the process variable or the output in user-selectable engineering units.
The loop-powered (two-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, nine 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.
