FAQ's of Duct Mount Humidity/Temperature Transmitter:
Q: How does the transmitter measure both humidity and temperature in air ducts?
A: The transmitter uses a capacitive humidity sensor to detect moisture and a precision thermistor for temperature readings. Both parameters are processed by an integrated circuit transducer and transmitted as an analog 4-20 mA signal for remote monitoring and control.
Q: What are the benefits of factory calibration for this device?
A: Factory calibration ensures that the sensor delivers highly accurate results (2% RH, 0.5C) right out of the box, eliminating the need for user calibration and reducing installation time and complexity.
Q: Where is this transmitter commonly applied?
A: This device is primarily used in air ducts for HVAC systems, building automation, and environmental monitoring applications where reliable temperature and humidity readings are essential.
Q: What installation process is recommended for this duct mount transmitter?
A: Mount the unit directly into the air duct using the provided hardware and standard 1.5-meter cable, then connect the screw terminal interface to your control system's 24 VAC/VDC power supply and analog input (4-20 mA).
Q: When should the transmitter be used regarding temperature and humidity ranges?
A: Utilize this product within a measurement range of -20C to 80C for temperature and 0-100% RH for humidity. Optimal performance is guaranteed within these specified ranges.
Q: What makes this transmitter suitable for long-term operation?
A: Its high accuracy, low humidity drift (<0.5% RH/year), IP65-rated enclosure, and factory calibration make it ideal for continuous operation in varying environmental conditions for HVAC and building management.
Q: Is the transmitter compatible with both AC and DC power sources?
A: Yes, the device operates efficiently with either 24 VAC or 24 VDC power input and has reverse polarity protection to prevent wiring errors.
