Inside structure is comprised of liquidcrystal unit displaying measured values, connector unit outputting measured values (DC 4~20mA) or Isolation RS-485communication (Option) Signal, HART communication signal, and Alarm Signal to outside, and 2 PCB Boards. Outsidestructure is comprised of Sensor unit for detection of gas leakage and Cable lead-in unit, and warning light. Warninglight is also made of SUS material in complete pressure-resistant, explosion-proof structure. Maintenance and repairoperations are convenient since calibration operation can be conducted outside of the Gas detector body by usingMagnet-bar.2. Structure1. Overview3.1. Basic Specifications3.
