Specifications
Overview
These flameproof gas sensor heads that can be fitted with a range of different sensor technologies (infrared, pellistor, electrochemical) for detection of a wide variety of gasses, depending on the sensor fitted.
They are Ex d certified components and as such must be fitted into compatible separately certified apparatus such a Flameproof (Ex d) junction box, Increased Safety (Ex e) junction box or Flameproof (Ex d) gas detector instrument housing.
Notes:
- The temperature ranges stated here refer to the GSH4 Ex’d sensor housing only. Refer to the relevant sensor data sheet for the sensor specifications.
- When the data communications facility is not required, the ends of the brown and orange wires should be insulated and secured to prevent electrical contact with any other wires or metalwork.
Features & Benefits
- Stainless steel construction with tamperproof protection
- For use with suitable separately certified industry standard junction boxes or OEM gas detector enclosures
- Compact Size
- Various mounting threads available M20, ½” NPT, ¾” NPT
- Can be fitted with a range of different sensor technologies (Infrared, Catalytic (Pellistor) or Electrochemical)
- Range of accessories available for gas application and environmental protection
