  1. direx Infrared exproof 4-20mA detector

  2. CO2 Range 0-2% vol. Resolution < 0.01% vol. Explosive gases Range 0-100% L.E.L. Resolution < 0.5% L.E.L. direx Exp advanced solution for detection of CO2 & explosives CH4 Infrared exproof detector 4-20mA standard for Carbon Dioxide -CO2-, Methane, Acetylene & Hidrocarbons CO2 C2H2

  3. Where to installdirex In those installations where other poisonous gases emissions affect pellistors - fluorine, silicon vapors, trichloroethylene, sulfur dioxide, sulphydric acid…-. DIREX is not affected by these gases. In those installations where there is a lack of Oxygen. DIREX, on the contrary to pellistors, it doesn´t require Oxygen to work For CO2 detection: As this is the one applicable and most accurate technology for this gas. In those installations where maintenance operations are particularly complex because of temperature and humidity conditions-: DIREX doesn´t need maintenance operations.

  4. Reliable detection without interferences of inhibitants of poisonous gases direx 4-20mA standard output 3 wires Exproof detector Box, adaptor & sensor ATEX certified Minimum impact of Temperature & humidity Constant checking of the sensor Presence of O2 not needed for detection Gas exposure does not reduce its useful life No interference of inhibitans or poisonous gases Quick response Minimum maintenance

  5. CONNECTIONS 4-20mA systems – 3 wires If the system is not provided of 4-20 mA input, but 0-5V DC or 0-10V DC, then a resistor must be connected to carry out the conversion. It must be installed in the receiver device, never in the detector. Depending on the voltage supply of the detector it is recommended a certain resistance to obtain a proportional voltage to the measurement range of the detector (see below)

  6. RS485 4-20mA Connection example CONNECTIONS EUROSONDELCO-SIEMENS CC62P DIREX can be connected to EUROSONDELCO / SIEMENS CC62P using an interface. Up to 2 interfaces per module line. Each interface allows the connection of 8 detectors automatically addressable. An external power supply 24V 6A should be connected for detectors powering.
