Programmable Fieldbus Temperature Transmitter

Jan. 23, 2008
The TFZ Programmable foundation fieldbus temperature transmitter can be installed on the same segment with all standard foundation fieldbus devices.
The transmitter converts a temperature sensor input to a foundation fieldbus H1, two-way digital communication protocol that is ready for interface to a DCS, computer-based SCADA system, or asset management software. The transmitter can save wire and installation costs by allowing up to 32 field devices (126 with repeaters) to be networked onto one, fieldbus H1 segment. It requires only 10.5mA for normal operation. The bus-powered, two-wire transmitter offers many input and operation choices. It sets up from the control room over segment wiring, using a standard foundation fieldbus configuration tool, to handle 14 RTD types, nine thermocouple types, as well as direct millivolt and resistance/potentiometer inputs. The transmitter is Factory Mutual approved for use in Class I, Division 1, Groups A, B, C, D and Class II & III, Division 1, Groups E, F, G hazardous areas. It also has NEMA 4X and IP66 ratings, approvals from ATEX, cFMus (US/Canada), IECEx, CSA, cCSAus, CENELEC/ATEX 94/9/EC and ANZEx, and is CE Conformant. The transmitter operates in ambient temperature ranges of -40 to +85°C (-40 to +185°F).  Moore Industries-International, Inc. www.miinet.com 818. 894.7111
