Oxygen gas transmitter OxyTrend

electrochemicalmulti-usewith display

OxyTrend is an Oxygen analyser based on electrochemical sensor. It can be configured as a 2-wire loop powered transmitter or, connecting further 2 or 3 wires, it can also have serial output RS485 ModBus RTU (in alternative or in addition to the analog 4-20 mA). OxyTrend can integrate 9 alternative types of sensor, depending on the measure to be achieved (from low traces, up to 100%). All sensors are insensitive to the presence of many background gases and hydrocarbons, making this instrument suitable for a variety of applications. Simple, reliable and cost-effective solution to measure O2 in extractive applications in safe and hazardous area (ATEX) Zone 1 / Zone 21 Measureable Gas Oxygen [O2] Main Features High Performances - Two-wire, loop powered 4-20 mA transmitter - Four or five-wire connection in case of use of the RS485 serial interface or 4-20 mA + RS485 respectively - ModBus RTU Master or Slave selectable by menu - Connectable with the ADEV 8RO4DI external module by RS485 to have 8 relays output and 4 digital inputs - Unique hardware for all wiring connection types - Optical through-the-glass buttons allowing menu operation without opening the housing - Graphical LCD Display with visualization in Auto-Range and possibility to switch to trend visualization - Use friendly menu and intuitive interface - High Accuracy Galvanic Sensors - Microprocessor-based technology and inner routine of electronic zero autocalibration - User selectable range - The version for hazardous area application is Ex-Proof and doesn’t require any Zener barrier in non-hazardous location - Low Maintenance - Sensor lifetime indication - NAMUR error indication
