When it comes to indoor air quality and occupant comfort, controlling humidity is critical. To control humidity a good humidity sensor is needed. In this video and post, I catch up with an old friend, Barry Gordon, who shows us what makes the humidity sensors from ACI a cut above the rest.
What Sets ACI Humidity Sensors Apart from the Competition
Regarding controlling indoor air quality and ensuring occupant comfort, humidity plays a crucial role. But not all humidity sensors are created equal. In a market flooded with options, ACI (Automation Components Inc.) humidity sensors stand out as a cut above the rest. In this article, we’ll delve into why ACI humidity sensors are the preferred choice for HVAC (Heating, Ventilation, and Air Conditioning) professionals and building automation experts.
Precision and Accuracy
One of the standout features of ACI humidity sensors is their precision and accuracy. These sensors are designed to provide incredibly accurate humidity readings, with an impressive one percent accuracy. This level of precision is not just a marketing claim; it’s backed by NIST (National Institute of Standards and Technology) certification. NIST certification means that these sensors meet the highest standards of accuracy and reliability, making them a dependable choice for critical applications.
Customization and Flexibility
ACI understands that different HVAC and building automation systems have varying requirements. ACI humidity sensors offer a high degree of customization and flexibility to cater to this diversity. These sensors have dip-switch selectable analog outputs, including 4-20mA, 0-5V, and 0-10V. This versatility allows professionals to choose the output that best suits their specific needs without the hassle of ordering different units for different applications. Whether it’s a 24V AC or 24V DC input requirement, ACI humidity sensors have you covered.
Drift is a common issue with many sensors, especially those used in long-term applications. However, ACI has addressed this concern effectively. Their humidity sensors are engineered to have minimal drift, ensuring that the readings remain consistent over time. With less than two percent drift over five years, ACI humidity sensors provide peace of mind for professionals who rely on accurate and stable measurements.
Calibration is a critical aspect of sensor maintenance. ACI recognizes the importance of easy and accessible calibration. Unlike many competitors, ACI humidity sensors offer on-board field calibration or validation. This means that professionals can calibrate the sensor directly on the circuit board using dip switches. This feature eliminates the need for complicated offset adjustments at the control system level, making the calibration process more efficient and user-friendly.
ACI doesn’t just stop at providing humidity sensors; they offer versatile solutions. Their sensors are available in various configurations, including combination units that can measure both humidity and temperature and CO2 levels. This versatility allows for a more comprehensive approach to indoor air quality control. ACI has a solution for every application, whether it’s wall-mounted sensors, sensors for washdown areas, remote probes, duct-mounted units, or outdoor air sensors.
ACI takes quality seriously. Unlike some manufacturers who batch-test only a small percentage of their sensors, ACI goes the extra mile. Every single product undergoes rigorous testing and calibration before it leaves the facility. This hands-on approach ensures that customers receive sensors that work flawlessly right out of the box. A comprehensive five-year warranty on their product range further reinforces ACI’s commitment to quality.
The Difference in Sensing Elements
The choice of sensing element can significantly impact a sensor’s performance, especially in high humidity conditions. ACI employs capacitive polymer-based sensing elements, setting them apart from competitors who often use resistive elements. The capacitive element offers a unique advantage – even if it becomes completely saturated or reaches 100% relative humidity, it can recover and continue functioning. In contrast, resistive-type sensors may fail when humidity levels exceed 90%. ACI’s choice of sensing element ensures reliability even in challenging environments.
In the world of humidity sensors, ACI stands out as a brand that prioritizes precision, customization, reliability, and versatility. HVAC professionals and building automation experts trust ACI humidity sensors to deliver accurate readings, maintain stability, and simplify calibration processes. With a commitment to quality and a range of innovative features, ACI has earned its reputation as the go-to choice for those who demand the best indoor air quality control. When it comes to humidity sensors, ACI is indeed a cut above the rest.
