Entity Parameters (for Hazardous Area Design)

Note: The 5043 is an associated apparatus. Connected temperature sensors in the hazardous area must be certified as intrinsically safe or be simple apparatus.

Configuration Options

Typical Applications

• Process Temperature Monitoring:​ RTD and thermocouple signals from hazardous area process vessels

• Furnace/Heater Control:​ Temperature measurement in heating applications

• Pipeline Monitoring:​ Temperature measurement for gas and liquid pipelines

• Reactor Control:​ Temperature signals from chemical reactors

• Storage Tank Monitoring:​ Temperature measurement in storage tanks

• HVAC in Hazardous Areas:​ Temperature control in classified buildings

• Motor Bearing Temperature:​ Monitoring of motor bearings in hazardous locations

• Any application requiring​ intrinsic safety isolation for temperature sensors in Zone 1 areas

Important Technical Notes

1. Sensor Certification:​ Temperature sensors installed in the hazardous area must be certified as intrinsically safe or qualify as "simple apparatus."

2. RTD Wiring:​ For highest accuracy, use 3- or 4-wire RTD connections to eliminate lead resistance errors. 2-wire connections are suitable for shorter distances.

3. Thermocouple Cold Junction:​ The 5043 provides automatic cold junction compensation. Ensure the unit is mounted in a location with stable ambient temperature for accurate CJC.

4. Configuration:​ Proper configuration of input type, range, and burnout response is critical. Document all settings for maintenance purposes.

5. Power Supply:​ Use a certified intrinsically safe power supply or ensure the loop power supply meets IS requirements for the entire circuit.

6. Grounding:​ Follow manufacturer's grounding recommendations. Typically, the isolator should be grounded to the system ground for noise immunity.

7. Environmental Considerations:​ The operating temperature range is -20°C to +60°C. For outdoor installations, ensure appropriate environmental protection.

8. Burnout Protection:​ Configure the burnout response based on process safety requirements. "Up-scale" is typically used for safety-critical applications.

9. Certification Compliance:​ Verify that the 5043's certifications match the hazardous area classification and temperature rating of your application.

10. Calibration:​ While the unit is highly accurate, periodic calibration may be required based on process criticality and quality system requirements.
