HART 7 temperature converter, loop-powered

Application

• The 3337 temperature converter measures a standard Pt100, TC J and K temperature sensor, and provides an isolated passive analog current and HART signal output.
• High 2 port isolation provides surge suppression and protects the control system from transients and noise.
• The 3337 can be mounted in the safe area or in Zone 2 / Division 2 areas.
• Approved for marine applications.

Technical characteristics

• Flexibly loop powered by 6.2...35 VDC via connectors.
• A 60 ms fast response time with simultaneous sensor error detection when selected.
• Selectable internal/external CJC.
• Excellent conversion accuracy in all available ranges, better than 0.05% of span.
• Meeting the NAMUR NE21 recommendations, the 3337 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.
• High galvanic isolation of 2.5 kVAC.
• Excellent signal/noise ratio of > 60 dB.

Mounting / installation / programming

• Selectable HART mode with HART 7 revision protocol enables extended device programming.
• Selectable DIP-mode for easy configuration of more than 1000 factory calibrated measurement ranges with HART read only feature.
• Selectable HART-mode to enable full HART read-write capability.
• The narrow 6.1 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.
