Gas detection in high-humidity or wet environments can be a challenge—especially when the air is saturated with water vapor. Traditional gas detectors often fail or deliver unreliable readings when exposed to moisture-laden streams. That’s where the B12 Wet Gas Transmitter from Analytical Technology, Inc. (ATI) stands out as a game-changer.
Engineered for 100% Humidity
Designed specifically for wet gas streams, the B12 Wet Gas Transmitter is built to perform in environments where other sensors fail. Whether you’re monitoring the outlet of a wet scrubber or sampling vent stacks saturated with moisture, the B12 provides accurate and consistent gas measurements where it counts.
Key highlights:
- 100% RH Compatible – Designed to operate in fully saturated environments
- Corrosion-resistant sensor – For long-term performance and durability
- Direct insertion or flowcell options – Flexible installation based on your setup
Built-in LCD Display for Easy Monitoring
The B12 is available in a NEMA 4X version with a built-in LCD display, allowing users to see real-time gas concentrations right at the detection point. This is a highly valuable feature for operators and technicians, eliminating the guesswork and enhancing on-site safety monitoring.
Note: The LCD display must be ordered at the time of purchase and cannot be added afterward.
Flexible System Integration
The B12 can operate as a standalone sensor, sending a 4-20 mA signal directly to your DCS, PLC, or SCADA system. For added functionality, it can also be paired with ATI’s B14 Alarm Receiver System, providing:
- Digital concentration display
- Three programmable alarm setpoints
- Remote alarm reset input
- 4-20 mA retransmission output
This flexible approach allows you to build a system tailored to your specific site needs and budget.
Choose Your Sensor Module
The B12 Wet Gas Transmitter is compatible with a wide range of gas sensors, allowing customization based on your application. Each sensor can be calibrated for custom detection ranges.
| Gas | Standard Range | Min Range | Max Range |
|---|---|---|---|
| Chlorine (Cl₂) | 0–20 ppm | 0–1 ppm | 0–100 ppm |
| Bromine (Br₂) | 0–20 ppm | 0–1 ppm | 0–100 ppm |
| Chlorine Dioxide (ClO₂) | 0–20 ppm | 0–1 ppm | 0–100 ppm |
| Ozone (O₃) | 0–20 ppm | 0–1 ppm | 0–100 ppm |
| Hydrogen Chloride (HCl) | 0–20 ppm | 0–10 ppm | 0–100 ppm |
| Hydrogen Fluoride (HF) | 0–20 ppm | 0–10 ppm | 0–100 ppm |
| Hydrogen Bromide (HBr) | 0–20 ppm | 0–10 ppm | 0–100 ppm |
| Hydrogen (H₂, %) | 0–4% | 0–1% | 0–10% |
Need a specific range? Custom calibrations are available for an additional fee.
Ordering Options & Enclosures
When configuring your B12 transmitter, choose from these enclosure and display options:
- Standard NEMA 4X: Rugged and suitable for most indoor and outdoor applications
- Explosion-proof enclosure: Galvanized steel for hazardous environments (Note: LCD display not available with this option)
- NEMA 4X with LCD display: For maximum utility and on-site monitoring, includes separated sensor with 25 feet of cable
All versions come with zero and span potentiometers for easy calibration and sensor cable that can be extended up to 100 feet.
