Capacitive RH sensors

电容RH传感器由一个陶瓷substrate on which a thin film of polymer is deposited between two conductive electrodes. The sensing surface is coated with a microporous metal electrode, allowing the polymer to absorb moisture while protecting it from contamination and exposure to condensation. As the polymer absorbs water, the dielectric constant changes incrementally and is nearly directly proportional to the relative humidity of the surrounding environment. Thus, by monitoring the change in capacitance, relative humidity can be derived.

Conductivity Sensors
-
- Conductivity measurements are widely used in industrial and environmental applications as a simple and inexpensive way to monitor and to control the ionic concentration in a solution.
Therefore, conductivity sensors can be used in many different fields of applications, ranging from water purification and quality control, over e-mobility and fuel cells to chemical, bio and pharmaceutical processing, IoT and agriculture as well as in food & beverage industries.
Due to the wide range of applications for conductivity sensors, the entire conductivity range, from low to very high ionic concentration in solution is covered. Monitoring of coolant quality in e-mobility and fuel cells for example takes place in very low conductivity ranges whereas desalination plants or medical applications display high conductivity values.
在不同电导率测量范围的电话for various sensor designs. The precision of a sensor in different conductivity ranges is highly dependent on size of sensor chip and electrode layout. Furthermore, the mobility of dissolved ions is tremendously affected by temperature. This temperature effect requires either temperature control of measured medium or compensation of measured conductivity. IOur ceramic-based conductivity sensors can include a resistive temperature sensor (Pt1000 IEC 60751 F0.3), allowing for accurate compensation directly at point of measurement.
What conductivity sensors are used for
- Conductivity measurements offer a simple and economical way to provide information on the ionic concentration and thus, the quality of measured medium of interest.
Conductivity sensors are widely used in industrial and environmental applications because they present a cost-effective, highly reliable measuring instrument that is independent of the sample medium.
Their applications range from water treatment and quality monitoring to leak detection in cooling & heat exchangers and condensers, to chemical processing, pharmaceutical and medical applications, food & beverage industries, and analytical laboratories.
-
Aqueous conductivity measurement
-
- In ground- and wastewater treatment as well as in water quality monitoring, conductivity sensors are used to determine ionic concentration of solution to subsequently remove impurities to ensure that water quality is adequate for application.
This concept is used, for example, in water quality monitoring of drinking water treatment, irrigation in agriculture, aqua farming, and swimming pools.
-
Non-aqueous conductivity measurement
-
- Applications are not limited to aqueous media. Conductivity sensors are also applied in non-aqueous media e.g. for quick, reliable, and continuous monitoring of coolant quality in e-mobility and fuel cells. Furthermore, they are incorporated in clean-in-place (CIP) and sterilization-in-place (SIP) processes, downstream processes to enhance quality of product.
Conductivity sensors will play a vivid role in upcoming IoT applications for example in healthcare and clinical diagnostics, agriculture and food & beverage. In medical devices they allow personal healthcare and diagnostic analysis, provide active drug dosing with feedback and are an essential part in dialysis. All above mentioned applications for conductivity sensors cover different conductivity ranges.
-
SI unit of conductivity
-
- The SI unit of conductivity is Siemens per meters (S/m) and is mostly given in mS/cm or µS/cm. Ultra-pure water has a conductivity of 0.05-0.1 µS/cm, tap water 300-800 µS/cm whereas sea water shows high conductivity values up to 56000 µS/cm. Measurements in different conductivity ranges call for different sensor styles. The precision of a sensor in different conductivity ranges is highly dependent on the size of the sensor chip and the electrode layout.
