PR 3333 Pt100 Temperature Converter

• High accuracy, better than 0.1% of span
• Slimline housing of 6 mm
• Excellent EMC performance and 50/60 Hz noise suppression
• Selectable < 30 ms / 300 ms response time
• Pre-calibrated temperature ranges selectable via DIP-switches

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

•  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.
