Buying Guide
What output should I use? Choose 0-5V for simple, short-run connections to basic data loggers. Pick 4-20mA for long runs and noisy environments, as current loops resist interference and support distant receivers.
Which duct-type considerations matter? Ensure the sensor housing fits your duct diameter and airflow path without obstructing airflow. Consider humidity and temperature sensing if your environment is humid or temperature-variable.
What about installation and wiring?
- Plan for proper cable routing to minimize heat exposure and EMI.
- Validate power supply compatibility with the transmitter’s requirements.
- Calibrate sensors when possible and document baseline readings for future maintenance.
What factors influence accuracy and reliability?
- Microprocessor-based data processing can improve response times but verify the data refresh rate.
- Environmental compensation helps maintain accuracy in varying humidity and temperature.
- Regular maintenance and sensor replacement timelines protect data integrity in critical systems.
How to choose between models?
- 0-5V options are best for simple setups and legacy controllers.
- 4-20mA options suit larger facilities and PLC-based monitoring.
- Consider brand consistency, availability, and ease of integration with your HVAC or control system.
