EKO Heat Flow Sensors are suitable for the direct measurement of heat flow inside materials, and the measurement of the radiant flow emitted by bodies such as refrigerators and containers.
Principle of thr measurement
There are three modes in heat transmission,thermal conduction, radiation and convection. If the heat flow sensor is placed on the surface of the material, it measures the total value of those three modes. If the sensor is placed inside the material, it directly measures the heat transmission caused by thermal conduction.
Based on Infrared absorbing principle, not only it is well selective to the target gas, but also detecting accurately and stable to gas concentration. The module is compact structure, free maintenance, application is various industry situation.
1.General description
The luminox family (lox) is a range of factory calibrated oxygen sensors which measure ambient oxygen partial pressure (ppo2) levels using the principle of fluorescence quenching by oxygen.
By default luminox measures ppo2 (mbar) and temperature (°c). An optional pressure sensor enables luminox to also measure barometric pressure (mbar) and to convert the ppo2 reading to an oxygen concentration (o2%).
The sensor benefits from low power operation, traditionally associated with electrochemical sensors, while providing a much longer lifetime due to the non-depleting sensing principle.
Luminox is ppo2 and temperature compensated, enabling accurate operation over a wide environmental range without the need for additional system components. Unlike other sensor technologies, luminox is very stable and robust, does not contain lead or any other
Hazardous materials and has negligible cross sensitivity to other gases.
2.Cleaning
The housing of the sensor can be cleaned using a damp cloth. The sensor should not be immersed in any cleaning media.
Full application and technical support can be provided by our knowledgable and highly experienced engineering team if required.
