Oxygen concentration sensor NEO445HT, 0-5%
- Oxygen concentration sensor with measuring range of 0-5 vol.-% O2 in H2
- Measurement of electrolysis gases (O2 in H2), installation in test benches
- The gas concentration is not changed by the measurement.
- Optionally also available with ATEX certification
- Encrypted CAN communication on demand
Oxygen concentration sensor NEO445HT
- Sensor system for measuring the oxygen concentration in hydrogen with temperature-, pressure- and humidity-compensated signal evaluation for automotive or industrial applications.
- Applicable in the range: 0.6 - 5 bar, 0 - 100% r.h. (non-condensing) and -40°C - 85°C.
- Optionally also available with ATEX certification
- A mathematical prediction algorithm ensures very short on and off times.
Key features
- Measuring range: 0-5 vol.-% O 2
- Carrier gase: hydrogen
- Measurement of electrolysis gases (O 2 in H 2), installation in test benches
- Measurement signal independent of pressure, temperature and humidity
- Signal output via CAN 2.0, Modbus RTU via RS485, 0-10V or 4-20mA
- The gas concentration is not changed by the measurement.
- Connection adapter available as transmitter or screw-in version for measuring gas in a housing or a pipe with optional external heaters
- Factory calibrated and ready for use
- Due to the large variety of possible operating conditions, sample extraction is rarely necessary.
- Encrypted CAN communication on demand
