NETC3 DIN-R: Pre-Calibrated Gas Detection Head for OEM Integration
Developing an industrial gas detection system requires much more than selecting a gas sensor.
Manufacturers must typically manage:
- Sensor integration
- Signal processing electronics
- Firmware development
- Mechanical enclosure design
- Hazardous area certification
- System calibration and validation
These activities increase development time, engineering complexity and certification costs, particularly in HVAC-R, refrigerant detection and industrial safety applications.
The NETC3 DIN-R Head was developed to simplify this process by combining sensing technology, electronics and certified enclosure into a single pre-engineered gas detection solution.
A Pre-Engineered Gas Detection Head for OEM Applications
The NETC3 DIN-R Head is a high-performance enclosure available in stainless steel or aluminium, designed to integrate N.E.T. NDIR or Thermal Conductivity gas sensors with built-in electronics.
Delivered pre-configured and pre-calibrated according to customer specifications, the device supports the full range of N.E.T. Infrared and Thermal Conductivity sensing technologies.
The solution is designed for:
- Gas detection system manufacturers
- Heat pump manufacturers
- Chiller manufacturers
- Refrigerant-based appliance manufacturers
