Monitoring Hazardous Gases in Ambient Air

The B12 2-Wire Gas Detectors are loop-powered instruments that transmit a 4-20 mA signal linearly proportional to gas concentration. Operated from a 24 VDC power supply, the transmitter will drive loads up to 675 ohms, sufficient for most monitoring applications. Alternatively, the unit can operate at 12 VDC with reduced output load for applications requiring battery operation. 

These detectors are normally supplied with the sensor closely coupled to the enclosure. However, for special applications, the unit can be supplied with separate sensors that can be located up to 25 feet from the transmitter. Sensor duct mounting adapters and sensor flow cells can also be provided for specific applications. 

Features

  • Capable of monitoring a large range of gases
  • Suitable for applications requiring battery operation
  • Available in an explosion-proof version

  • Industrial Pre-Treatment

    Industrial pre-treatment is a crucial stage in the water cycle, occurring before wastewater enters municipal treatment facilities. It involves the removal of contaminants, pollutants, and other harmful substances from industrial wastewater streams to meet regulatory standards and protect the environment. This process typically includes physical, chemical, and biological treatment methods tailored to specific industrial processes and pollutants. By effectively pre-treating industrial wastewater, we can safeguard water quality, prevent damage to treatment infrastructure, and ensure the overall health of ecosystems downstream.
