The detector head is a fixed type detector head that detects leak of combustible gases and that performs the alarm activation when the gas concentration is over the setting value.
The detector head is a safety unit, not an analyzer or densitometer which performs quantitative/qualitative analysis/measurement for gases. Please fully understand the features of the
detector head before using it, so that it can be used properly.

• Detector head draws air with the built-in pump, and detects abnormalities in the air caused by presence of gases or other reasons (leak) with the built-in gas sensor.
• The concentrations of detected gases are displayed on the seven-segment LED.
• The detector head has a built-in alarm contact and can be used either as a gas alarm, fault alarm, or common (gas, fault) alarm.
• The detector head has a built-in low flow rate detection function and can trigger a fault alarm when the flow rate inside the tubing drops below a fixed rate.
• The detector head outputs gas concentration in 4 – 20 mA.
• SD-D58 series have two types of power supply specifications.
  SD-D58･AC AC power specification 100 – 110VAC
  SD-D58･DC DC power specification 24VDC
• TYPE GP H/TYPE NC H have HART communication function.
• Production process: Electrolyte filing
• Installation point: In / On the machine
• Purpose: Explosion prevention
• Detector model: SD-D58･DC (TYPE GP)(ATEX)
• Main measuring gases: DMC
• Measuring range: 0-100% LEL
• Advantages:
  • Buit-in pump suction type
  • With concentration display function
  • ATEX
• Benefits: Quickly gas detection with high performance built-in pump. Equipped with a low flow detection sensor to notify of failures. 
  Unitization of replacement parts. Easy replacement of sensor and pump units.
