Description

Description
  • TRANSMITTER TYPE(4~20mA)
  • MODEL : QM-4700
Features
  • Ambient diffusion gas detector with self-diagnostic function using micro-process technology
  • Gas detector with overvoltage protection and malfunction prevention function, featuring a constant voltage channel for safe operation of detection sensors
  • Internal pressure explosion-proof
  • Calibration and program setting ZERO point, Span ( Automatic Setting with no Volume except for 4~20mA)
  • Calibration and maintenance by one person
  • Minimization of the impact of noise - temperature/humidity
  • Connection of the analog standard output(4~20mA) signal to DCS & PLC monitoring system
  • Install the system in hazardous areas at industrial sites to measure combustible gases in real-time, and provide 4~20mA standard output and connect to control devices, alarm devices, and monitoring systems
