RT-FLEX Head-Transmitter for Pt100, programmable - West Control Solutions - #1

Text version of the page

GENERAL This programmable 2-wire Pt100 transmitter is designed for mounting inside the standard connecting head of a temperature sensor. It is the continuation of the UNIFLEX T/TEX series and fulfils all the requirements regarding flexibility, reduced stocks and safety against electromagnetic effects. By means of a PC and the standard programming set, adjustment for the required measuring range and parameters is performed. DESCRIPTION The transmitter has an input for a Pt100 sensor. Measurement is possible in 2-, 3- and 4-wire connection TECHNICAL DATA INPUT Resolution 14 bit Resistance thermometer Pt100 Span: 25 K up to 1050 K Span start: -200 °C up to 825 °C Span end: -175 °C up to 850 °C Smallest configurable step: 0,1 K Sensor current: + 875 °C Measuring cycle: nominal <700 ms Damping: adjustable 0...30 s Permissible input interferences (to DIN IEC 770 6.2.4.2) OUTPUT Standard signal: 4...20 mA Signal direction: direct, inverse Load [ ] R [ ] [ ] U V A R load Supply lead = - - 8 0,023 Ù Output signal limitation: programmable 3,5mA / 23 mA Loop monitoring: programmable upscale 23 mA / downscale 3,5 mA Characteristic: temperature linear Resolution: 12 bit Conformity error (Inclusive conformity error) Span Error 250 K ± 0,1 % of span RT-FLEX Head-Transmitter for Pt100, programmable 2-, 3- and 4-wire connection Sensor correction Setting via PC àtested
