Pt100 converter

Application

• The 3102 temperature converter measures a standard 2-, 3- or 4-wire Pt100 temperature sensor, and provides an analog voltage or current output.
• The 3102 can be mounted in the safe area or in Zone 2 / Division 2 areas.
• Approved for marine applications.

Technical characteristics

• Flexibly powered by 24 VDC (±30%) 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 3102 provides top measurement performance in harsh EMC environments.
• The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
• A visible green LED indicates operational status of the unit and the input sensor.
• 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.
