Rapidox 2100-OEM-RSB and DIN

Product Information

The Rapidox 2100-OEM-RSB range are special miniaturised 24V OEM versions of our existing high-performance zirconia oxygen (O2) analyser. The compact new design allows integration into the tightest of spaces with the exact same performance specs and features of our existing OEM analyser. The board is fitted with a robust cabled zirconia sensor, which is ideal for providing fast and accurate remote in-situ gas analysis over the full oxygen range 10-20ppm to 100% O2.

Product Information

Zirconia oxygen sensors are extremely rugged and particularly suitable for monitoring inert atmospheres and aggressive industrial applications directly within manufacturing processes such as metal 3D printers, soldering ovens and furnaces. High temperature (650°C) and vacuum applications are particularly suited to this model. The OEM has auxiliary sensor and temperature (type K) inputs for connecting additional sensors such as pressure, vacuum and dewpoint and can also monitor local ambient temperature and humidity conditions for improved stability.

The analyser is supplied in four packages to meet the demands of any customer: a basic circuit board, a custom DIN rail version and a full metal DIN rail enclosure, with or without local display and keypad. The sensor cable can be made to any length up to 25m and there is a choice of sensor mounting options including aluminium and stainless manifolds as well as vacuum fittings (ISO-KF and CF). Fully programmable analogue (voltage and current) outputs and alarm relays as well as RS232 / RS485 digital signalling are standard. Rapidox digital communications protocol and Modbus-RTU is included as standard. The analyser is designed specifically for seamless integration into PLC systems. Finally, the Rapidox 2100-OEM-RSB complies with EMC Directive 2004 / 108 / EC. UL/ETL Certification Number: UL-61010-1.

Customer Testimonials

“As an engineer, one of the most positive things I can say about Cambridge Sensotec is the support and information that we have received both pre and post-purchase. I don’t think I’ve worked with another organization as a customer that was so helpful in sharing critical technical information to solve my exact needs. Additionally, I’ve always been able to get in contact with the right person to solve my issues and the support we have received has always enhanced my understanding of the sensor and communication with the rest of the system.

Cambridge Sensotec was very understanding of being the sole vendor that we can reasonably work with to solve this issue due to their experience and proprietary knowledge of the PLC system from the system we are modifying. The only suitable sensor for our setup in terms of chemical compatibility and sensing capabilities was new to the company but we were able to get bespoke firmware for us to communicate with our system’s PLC in parallel with their development of the standard sensor for the firmware. Even with all of the work that went into development and the cost of the hardware, the overall cost and timeline were very reasonable.”
