FAQs of Temperature and Humidity Transmitter:
Q: How do I install the temperature and humidity transmitter?
A: The device is designed for easy installation as a wall-mounted unit. Simply affix it to a suitable flat surface in your monitoring area, connect the 1.5 m cable to your system, and integrate it with your existing analog or digital data interface, such as RS485 Modbus, 4-20mA, or 0-10V. The ABS plastic housing and IP65 rating allow installation both indoors and in protected outdoor locations.
Q: What applications is this transmitter suitable for?
A: This transmitter is ideal for environmental monitoring in HVAC systems, greenhouses, industrial automation, and other settings requiring precise climate control. Its broad measuring range and robust protection make it a versatile solution for monitoring temperature and humidity in both commercial and industrial environments.
Q: When should I replace the transmitter or its sensor?
A: With a life span exceeding 10 years, the transmitter is built for long-term reliability. Regular inspections are recommended, but sensor replacement is generally not necessary unless exposed to extreme contamination or physical damage. Ensure quick replacement if performance accuracy noticeably decreases.
Q: Where can the transmitter be used given its protection class?
A: The IP65-rated housing protects against dust and low-pressure water jets, making it suitable for use in dusty or humid environments, such as factories, agricultural facilities, or indoor and semi-outdoor installations. It should not be submerged or used in areas subject to continuous direct water exposure.
Q: How does the automatic control mode benefit my application?
A: The digital/automatic control mode enables seamless integration with automation systems, reducing the need for manual adjustment. This feature allows for real-time climate regulation, improving operational efficiency, minimizing errors, and supporting hands-off operation in stable processes.
Q: What is the process for connecting to different output signals?
A: Select the output type that matches your control systemanalog (4-20mA or 0-10V) or digital (RS485 Modbus). Wire the transmitter following the included schematic diagram and supply the appropriate power (AC 220V or DC 24V). The device will deliver real-time, accurate data compatible with your automation and data logging equipment.
Q: What are the benefits of using a digital CMOS sensor in this transmitter?
A: Digital CMOS sensors provide high-speed, highly accurate readings with minimal drift over time. This ensures the transmitter delivers stable, precise temperature and humidity measurements, offering reliability for critical applications and reducing long-term calibration and maintenance requirements.
