The NETC3 DIN-R Head by N.E.T. is a high performance enclosure, made of stainless steel or aluminium, which includes a specific gas sensor and integrated electronics. Designed for versatility, it can serve as a core component for fixed gas detection systems or as a fully compliant, standalone field device.
The NETC3 DIN-R Head is the ideal solution for gas detection system manufacturers, or heat pump/chiller and other refrigerant appliance manufacturers looking to streamline their development process. By adopting this ready-made solution, users can avoid the substantial investment required for:
- Sensor Sourcing: Identifying or developing specialised sensors.
- R&D: Developing complex electronics and firmware for signal processing, compensation, and linearisation.
- Engineering: Designing proprietary detection heads.
- Certification: ATEX/IECEx certification process.
The NETC3 DIN-R Head supports the full range of N.E.T. Infrared (IR) and Thermal Conductivity sensors and is pre-configured and pre-calibrated according to the customer’s specific requirements.
The NETC3 DIN-R Head features an RS-485 MODBUS output, alongside dedicated fault and
alarm relays, operating on a 12-24VDC power supply.
The flameproof enclosure includes an integral stainless steel sintered filter to ensure safe atmospheric sampling. An optional adapter is available to provide an IP65 rating and dust protection (II 2GD protection).
The NETC3 DIN-R Head can be opened, which allowes straighforward sensor replacement at the end of its operational lifespan.
The NETC3 DIN-R Head features an M46 external thread for easy accessory mounting. For rear integration, three thread options are available: 3/4”, 1”, or M20.
