The B12 Ozone Detector is a robust, two-wire 4-20 mA gas transmitter that excels in providing reliable and linear ozone concentration measurements. Designed for easy integration and broad compatibility with various monitoring applications, the B12 is powered by a 24 VDC supply and can drive loads up to 675 ohms. For portable or off-grid setups, the B12 can also operate at 12 VDC, albeit with a reduced output load, making it ideal for battery-operated systems.
Key Features
- Two-Wire, Loop-Powered Operation: Simplifies installation and ensures stable, accurate output.
- Compact and Versatile Design: The transmitter is housed in a NEMA 4X polystyrene enclosure, offering protection from harsh environmental conditions. For extreme environments, an explosion-proof enclosure is available.
- Optional LCD Display: For easy, on-site gas concentration readings, you can order the B12 with a built-in LCD display. This option must be selected during the initial order, as it cannot be added later.
- Flexible Sensor Placement: The B12 offers the option of a separated sensor, allowing the sensor to be placed up to 25 feet away from the transmitter, perfect for applications where space is limited or safety is a concern.
Accurate and Reliable Performance
The B12 uses electrochemical sensors that are ideal for ambient air and ventilation ducts. These sensors are highly accurate, with ±5% precision in measuring ozone concentration. However, they are not suited for environments with extremely dry air or condensing gas streams.
The transmitter’s performance is optimized by a range of built-in features:
- Zero and Span Potentiometers: These allow fine-tuning of calibration, ensuring reliable long-term performance.
- Low Span Drift: The B12’s sensors experience less than 3% drift per month, making it highly dependable in most industrial settings.
Tailored for Various Applications
The B12 is designed to suit a wide array of gas detection applications, and it’s available with sensors for gases other than ozone. These gas detection options can be selected via the product’s drop-down menu during the ordering process.
In addition to ozone detection, the B12 can be configured for applications in industries such as:
- Chemical processing
- Petroleum refining
- Ventilation and HVAC systems
Whether it’s monitoring ozone levels in refineries or ensuring the safety of ventilation ducts in industrial settings, the B12 offers flexibility and reliability.
Installation Options
The B12 transmitter’s installation process is straightforward, with various configurations to suit your specific requirements:
- Duct Mounting: The duct insertion sensor allows the detector to be inserted into a duct or pipe for precise gas monitoring in ventilation systems.
- Explosion-Proof Enclosures: For hazardous environments, the B12 can be ordered with an explosion-proof galvanized steel enclosure, rated Class 1, Div. 1, Groups B, C, & D. This option ensures that the transmitter can safely operate in areas where flammable gases are present.
- Separated Sensor: If needed, the sensor can be mounted up to 25 feet away from the transmitter, ensuring flexibility in cramped or hazardous areas.
