The OS-4 Ozone Switch is a cutting-edge remote mount ozone sensor that brings accuracy, reliability, and convenience to ozone monitoring. Equipped with the SM-EC sensing module, it can detect ozone concentrations from up to 100 meters away from the base unit, making it ideal for industrial and agricultural applications where continuous monitoring and control of ozone levels are critical.
Key Features of the OS-4 Ozone Switch:
- Remote Sensor Capability: The OS-4 uses a remote sensor module that can be placed away from the base unit, ensuring the instrument itself isn’t exposed to high ozone areas. The sensor comes with a pre-calibrated module, making replacement and calibration easy.
- User-Friendly Interface: The LCD screen with indicator lights provides a clear readout of ozone levels and equipment control status. This easy-to-read display ensures operators can monitor ozone concentrations and system status at a glance.
- Ozone Control Like a Thermostat: The OS-4 can be programmed to control ozone generators and alarms based on adjustable ozone concentration set-points. With its digital meter readout, users can easily set and monitor the desired ozone concentration.
- Temperature and Humidity Compensation: The sensor readings are automatically compensated for temperature and humidity fluctuations, ensuring consistent accuracy even in variable environments.
- Wide Power Compatibility: The OS-4 operates from 12-24 VDC and can be powered using AC adapters available globally, making it flexible for various power setups.
- Programmable Alarms: The OS-4 features a programmable turn-on and turn-off set-point for controlling ozone generators. Additionally, it has a 0.1 ppm safety standard alarm that alerts operators when ozone levels exceed safe limits.
Typical Applications:
- Agricultural Storage Monitoring: Monitor ozone levels in areas storing fruits, vegetables, and other perishable products to prevent spoilage and contamination.
- Ozonated HVAC Systems: Ensure proper ozone levels in HVAC systems for effective disinfection and air quality management.
- Ozone Generator Control: Use the set-point controlled relay to manage the output of ozone generators, ensuring they operate within safe and efficient parameters.
- Ozone Leak or Failure Alarm: Detect leaks or failures in ozone generators and alert operators immediately, preventing accidents and ensuring safe operations.
Specifications:
- Range: 0.03-20 ppm with an electrochemical sensor for accurate detection.
- Accuracy: 10-15%, depending on the application.
- Operating Conditions: 5-40°C temperature range, 20-95% relative humidity.
- Power Requirements: 12-24 VDC, 300 mA.
- Relay Output: SPDT relay rated for 5 amps, 250 VAC.
- Case: Made of flame-resistant ABS, ensuring durability and safety.
Range Selection:
The OS-4 comes equipped with the SM-EC Electrochemical Sensor featuring a 0-20 ppm range, making it ideal for ozone control applications in industrial environments like odor control, food storage, and more. The SM-EC sensor excels in high-humidity environments and areas with volatile organic compounds (VOCs), providing enhanced accuracy compared to traditional HMOS sensors.
While the 0-20 ppm sensor is excellent for industrial control, it may not be suitable for certain human safety applications, where different detection thresholds are required.
Components of the OS-4:
- OS-4 Base Unit: Contains the relays, voltage outputs, and the LCD display.
- SM-7 Sensor Module: Houses the ozone sensor and measures ozone concentrations.
- SM-EC Sensor Chip: The replaceable, pre-calibrated sensor chip used in the SM-7 module for long-term reliability and low-cost maintenance.
Remote Sensor Setup:
The OS-4 is shipped with a 6-foot cable connecting the OS-4 base unit and the SM-7 sensor module, allowing for flexible installation. For installations requiring longer distances, the OS-4 can support cable lengths up to 100 meters. Standard telephone wire works for distances up to 100 feet, but for distances beyond that, shielded cable with 22-gauge wire is recommended. In testing, 18-gauge shielded cable has been used successfully at distances up to 1,000 feet, making the OS-4 an adaptable solution for a wide range of setups.
Accessories and Monitoring Options:
The OS-4 is compatible with a variety of accessories, including alarms and data loggers, allowing you to expand its functionality. Additionally, you can integrate it with a Wireless Monitoring & Data Logging Kit, which connects the OS-4 to the internet, enabling real-time monitoring and instant notifications via text and email alerts.
Conclusion:
The OS-4 Ozone Switch is a versatile and reliable tool for monitoring and controlling ozone levels in a variety of industrial settings. Whether you’re managing ozone in an agricultural storage facility or controlling an ozone generator, the OS-4 provides accurate, easy-to-read data, and effective control functionality. Its remote sensor capability, programmable set-points, and compatibility with accessories make it an excellent choice for anyone needing reliable ozone detection and control.
