Our sensor components
Neroxis offers gas and pressure sensors, pre-calibrated modules and in-line probes to cover multiple applications in the fields of environmental and industrial control.
NEROXIS technology is based on the manufacture of microthermal conductivity sensors in micro-electronic MEMS silicon technology. This manufacturing process ensures the reliability and reproducibility of the components at a competitive cost.
• Miniaturisation of the sensors
• Low-energy consumption of sensors and modules suitable for portable instruments
• Provision of pre-calibrated modules compensated for temperature, humidity and pressure that can be directly incorporated into OEM equipment
The principle of operation of a microthermal conductivity sensor (MTCS) for gases relies on the transfer of heat flow from a heated resistor, located on an insulated dielectric membrane, to the cold part of the device. The heat flow depends directly on the conductivity of the gas. The principle is based on the measurement of the signals from the heated part of the device and from the ‘cold’ part at room temperature.
Applications for gas measurement
Monitoring of H2, CH4, CO2, LPG gases for indoor and outdoor air
• Process control in the food industry (e.g. measurement of CO2 in soft drinks)
• Hydrogen sensors for fuel cells and combustion engines
• Measurement of CH4 in biogas plants
• Detection of refrigeration gases (CFC, PFCs, HFCs, etc.)
• Electronic products (e.g., helium control for diving equipment)
• Monitoring of respiratory systems (medical)
• Control of leaks in closed systems operating under inert gas (e.g. strain gauges, quality control of hard disks, etc.)
Low cost and low consumption
Reproducibility and mass production
Calibration/compensation in the plant
H2, CH4, CO2, He etc selectivity based on a specific detection algorithm
Fast response time <100 ms 'Plug and Play' modules Compatible with portable devices
Applications for pressure measurement
• Fixed and portable analytical instruments
• Leak detection and primary vacuum control in closed systems (e.g. kinetic energy storage systems)
• Vacuum equipment used in the semi-conductor industry
• Food industry (vacuum packaging machines)
In general, the small footprint of the Pirani miniature sensors enables their integration into any primary vacuum system requiring their control (e.g. control of sealing, potential corrosion, or inadvertent opening)
High performance (excellent TCR)/repeatability due to the Pirani MEMs utilisation approach, which is possible in corrosive atmospheres (gold version)
Sensor compatible with a standard circuit of the ‘Constant Excess Temperature’ type, allowing its use in all pressure ranges, and the implementation of temperature compensation.
Ease of assembly using the SMD version of the sensors. Reproducibility of the sensors linked to batch production, facilitating their replacement and the calibration of the measuring instruments.
Vacuum measurement and temperature compensation on the same chip
Optimal sensitivity in the 10-2 to 10+2 mbar range.
Measuring range extending from 10-5 to 10-3 mbar
