In environments where toxic and combustible gases pose serious threats, reliable detection and monitoring are crucial. ATI’s D12 Toxic Gas Transmitter stands out as a versatile and powerful tool, designed to streamline your gas detection needs by accommodating up to 46 different sensors. This unique capability reduces the need for multiple transmitter models, making it a cost-effective and flexible solution for diverse industrial applications.
A Single Transmitter, Multiple Sensors
The D12 Transmitter’s ability to accept a wide range of sensors means you can rely on a single model to monitor various gases. This is made possible by the innovative self-aligning sensor holder, which plugs in effortlessly and ensures automatic sensor recognition and verification as soon as contact is made. This feature simplifies maintenance and sensor replacement, making the D12 a user-friendly option for both technicians and operators.
Key Features of the D12 Toxic Gas Transmitter
The D12 Transmitter is packed with advanced features that enhance its functionality, ease of use, and reliability:
- LCD Graphics Display: The large, easy-to-read numbers on the display show gas concentrations, alarm statuses, and setup menus. When operating in 3-wire mode, the display is backlit for better visibility in low-light conditions.
- Internal Data Logger: Store measured gas values at user-defined intervals. Data can be easily recalled on the LCD display or downloaded using the MODBUS™ interface, ensuring that critical information is always accessible.
- Non-Intrusive Operation: All operating functions—including calibration, alarm setup, and data view—can be managed using a magnetic tool, eliminating the need to open the enclosure for adjustments.
- Password Protection: Secure your settings with a 4-digit password. Operators can review functions, but only authorized personnel can make changes, enhancing security and control.
- Modular Electronics: The D12’s electronic assembly plugs directly into the power supply board, allowing for easy installation and quick replacement in case of faults.
- Explosion-Proof Enclosure: Designed for hazardous environments, the D12’s cast aluminum housing is UL, FM, and CSA certified, making it suitable for Class 1, Division 1, Group B, C, D locations.
- Scalable 4-20 mA Output: The output range is programmable within the limits set by the sensor, allowing for customizable measurement ranges.
- Internal Alarm Relays: Optional relays can be used for local alarms, programmable for various settings such as set point, hysteresis, on-delay, and off-delay. A remote reset feature is also included.
- Analog and Relay Output Simulation: Perform complete loop testing and activate alarm relays on command without needing to apply gas to the sensor, simplifying system checks and maintenance.
- Serial Communication Interface: Available with either HART™ or MODBUS™ protocols, providing comprehensive access to data and alarm setup.
Simplified Sensor Interface
The D12 Transmitter offers a straightforward user experience with its easy-to-use push buttons, allowing operators to navigate the display menus quickly. The enclosure cover can be easily unscrewed for direct access to the sensor, further enhancing the convenience of operation.
Unmatched Flexibility with Customization Options
ATI’s D12 Transmitter is highly customizable, allowing you to configure the system to meet your specific application needs. From sensor modules to transmitter types and sensor holder styles, the D12 can be tailored for optimal performance in any environment. Options include:
- Sensor Modules: Choose the gas type and detection range needed for your application.
- Transmitter Type: Select between electrochemical sensors for toxic gases or catalytic bead sensors for combustible gases.
- Sensor Holder Styles: Integral or remote sensor systems are available, depending on your installation requirements.
- Digital Output: Standard 4-20 mA output is provided, with optional HART™ or MODBUS™ interfaces.
- Accessories: Various accessories like calibration adapters, flowcell assemblies, and sensor splash guards are available to enhance your setup.
Advanced Auto-Test Generator
For applications requiring regular verification of sensor performance, the D12 Transmitter offers an optional Auto-Test Generator. This system automatically tests the sensor’s response by exposing it to a small amount of gas at scheduled intervals. If the sensor fails to respond after three attempts, a fault alarm is triggered, ensuring that your monitoring system remains reliable and accurate.
Why Choose ATI’s D12 Transmitter?
The D12 Toxic Gas Transmitter is designed for users who demand reliability, versatility, and ease of use. Its robust construction, wide sensor compatibility, and advanced features make it an indispensable tool for any industrial setting where toxic or combustible gases are present. Whether you need to monitor a single gas or multiple gases, the D12 offers the flexibility and performance you need to keep your environment safe.
