GTD-2000Ex Gastron | Thiết bị dò khí dễ cháy thông minh

Overview

• GTD-2000Ex flammable Gas detector has been developed to prevent accidents beforehand by detecting variousleaked gases generated in industry fields such as plants producing or using flammable gas, gas storage place,manufacturing processes, etc.
• GTD-2000Ex flammable Gas detector is installed in areas with a risk of gas leakage  to display measured values with
• LCD, OLED  installed in the detector by continuous detection of gas leakage, providing DC 4~20mA standard output.
• Also, DC 4~20mA standard output can connect up to the maximum of 2500m (upon using CVVS or CVVSB 1.5sq↑ Shield Cable) in transmission distance of output signals of detector and receiving unit.
• The present GTD-2000Ex flammable Gas detector should be used at altitude of less than 1000M above sea level.

Structure

• GTD-2000Ex body is made of aluminum alloy material in a structure of complete pressure-resistant explosion-proof type(Ex d IIC T6),with the gas sensor module being composed of stainless steel material. It can be installed in the areas with a risk of leakage and explosion of all flammable gases, displaying leakage situation of gas at the installed field by embedding LCD, OLED in the detection unit. Inside structure is comprised of display unit displaying measured values, terminal unit for outputting measured values (DC4- 20mA) to outside and one PCB. Outside structure is comprised of detector unit for detection of gas leakage and Cable lead-in unit. Maintenance and repair operations are convenient since calibration operation can be conducted outside of the Gas detector by using Magnet-bar outside of the detector  unit body.

Advantages

• Continuous detection of flammable gases in explosion hazardous area with flame proof structure
• Self diagnosis function with built-in Microprocessor
• Detection gas from low to high concentration owing to various detection principle
• Stable quality and proved detection principle for service life
• Built-in back light LCD or OLED display
• Easy Configuration of monitoring by HART communication
• Auto calibration and program setting with a magnet bar 4-20mA (Current source or Sink) output signal
• With the alarm unit – Normal : Green LED – Alarm : Red LED, Buzzer(95 dB) – Trouble : Yellow LED
• Calibration and maintenance by one-man
