ACI A/RH3-R-LCD-420 : Room Relative Humidity Sensor, 3% Accuracy, RH Outputs: 4-20mA, Room (R) Infinity Enclosure (Beige) with LCD, Made in USA
The ACI Relative Humidity with LCD utilizes a thermoset polymer capacitive sensing element with integral hydrophobic filter to deliver a proportional analog current or voltage output with long term reliability. The styling of the white, wall mounted enclosure with hinged cover makes it suitable for use in a wide variety of applications. The ACI RH LCD series products can be powered with either an AC or DC supply voltage and features a large, backlit display which improves the overall visibility of the display. Other features include onsite field calibration through a single point offset through the programming of the device using the integral keypad. All units must be ordered with one of the supported output signals of 4-20 mA, 0-5 VDC, or 0-10 VDC
The applications for the ACI RH Room Series include:
- Humidification and Dehumidification: These sensors can be used in systems that control humidity levels, ensuring optimal conditions for comfort or specific processes.
- Monitoring Indoor Space Humidity: The sensors provide continuous monitoring of humidity levels in indoor spaces, allowing for adjustments and maintaining a comfortable environment.
- Clean Rooms: In clean room environments, precise humidity control is crucial for maintaining the integrity of sensitive processes and materials.
- Hospitals: The RH room sensors can be used in hospitals to monitor and control humidity levels, contributing to patient comfort and preventing the growth of harmful microorganisms.
- Process Control: Industries that rely on specific humidity levels for manufacturing or other processes can benefit from these sensors for accurate monitoring and control.
- Laboratories: Research and testing laboratories often require precise humidity control to ensure accurate results and maintain the integrity of samples.
- Museums: Maintaining proper humidity levels is essential for preserving delicate artifacts and artworks in museums.
Schools and Office Buildings: The sensors can help create a comfortable and productive environment for students and employees by regulating humidity levels. - Data Centers: Data centers need to maintain stable humidity levels to prevent equipment damage and ensure optimal performance.
- ESD (Anti-Static) Control: In environments sensitive to electrostatic discharge, monitoring and controlling humidity can help mitigate ESD-related risks.
