Application
The 3333 temperature converter measures a standard 2-, 3- or 4-wire Pt100 temperature sensor, and provides a passive analog current output signal.
The 3333 can be mounted in the safe area or in Zone 2 / Division 2 areas.
Approved for marine applications.
Technical characteristics
Flexibly loop powered by 3.3...35 VDC via connectors.
< 30 ms fast response time with simultaneous sensor error detection when selected.
Selectable 300 ms response time when signal dampening is needed.
High conversion accuracy in all available ranges, better than 0.1% of span.
Meeting the NAMUR NE21 recommendations, the 3333 provides top measurement performance in harsh EMC environments.
The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
All terminals are protected against overvoltage and polarity error.
Excellent signal/noise ratio of > 60 dB.
Mounting / installation / programming
Selectable DIP-settings for easy configuration of more than 1000 factory calibrated measurement ranges.
The narrow 6 mm housing allows up to 165 units to be mounted per meter of DIN rail, without any air gap between units.
Wide ambient temperature range of -25...+70°C.
