PTT’s Toxic and Combustible Gas Transmitter will accept up to 46 different sensors, greatly reducing the need for multiple gas transmitter models. The self-aligning sensor holder simply plugs in, with automatic gas sensor recognition and verification when contact is made.
For many toxic and combustible gases, PTT offers a unique sensor response testing system unmatched by any competitive transmitter. Even outdoors in high wind conditions, the Auto-Test system provides reliable response checks to ensure system integrity. Sensor response is verified with an actual gas sample, generated on demand. Generators store run time information accessible to operators, and are automatically tested for compatibility with the installed sensor.
Gas transmitters provide useful features that simplify installation, operation, and maintenance. From clear menu-driven setup pages to large numerical display of gas values, you simply can’t find a more versatile gas transmitter. Gas concentrations are displayed in large, easy to read numbers. The display also provides alarm indication and complete menus for setting up operating parameters. Backlighting is available when operating in 3-wire mode.
Operating functions such as calibration, alarm setup, alarm reset, data view, and setup options are all available using a magnetic tool. It is not necessary to open the enclosure when making adjustments.
Gas transmitters are designed for operation in hazardous areas. The cast aluminum housing for the gas transmitter is rated for Class 1, Division 1, Group B, C, D locations and is UL, FM, and CSA certified.
The gas transmitter is available with either HART™ or MODBUS™ protocol. The HART™ protocol supports the HART™ Universal and Common Practice Commands at 1200 baud using the Bell 202 FSK modem standard. The MODBUS™ protocol supports 9600 baud access to concentration and status information, and supports alarm setup and many other functions on either RS485 or RS232 (software selectable).
