Humidity measurement Along with temperature, humidity is a very important process variable. For example, the relative humidity of an environment has a major effect on our sense of well being and state of health. In industrial processes, the right humidity level is often a determining factor for the competitiveness and quality of products. A correctly adjusted humidity level can also contribute to considerable savings in energy consumption. The list of applications in which air humidity measurements are important could go on forever. Continuous monitoring of the air humidity is highly relevant...

Capacitive measuring probes Capacitive measuring probes work according to the principle of absorption. This means the sensor constructed in the multilayer system functions essentially like a moisture-dependent condenser. Water molecules bond to a special hygroscopic polymer layer. Depending on the retained moisture, the result is a change of the dielectric constant and therefore a change in capacity. Then a downstream electronics unit generates a corresponding standardized electrical output signal.

Humidity measurement Capacitive measuring probes CO2 measuring probes Hygrometric measuring probes and hygrostats Wireless measured value transmission The introduction of capacitive sensors for humidity measurements has opened up entirely new possibilities for both industrial and air conditioning applications. Some of the outstanding features of these devices include small sizes and fast response times. They are also largely impervious to pollutants, dust, and condensation. But above all, the complete measurable range of humidity and wide temperature range as well as the mechanical and electronic...

CO2 measuring probes These devices from JUMO work according to the infrared principle (NDIR). The gas exchange with the CO2 sensor takes place via a membrane through diffusion. That means the air circulates in a closed system and that no pollutants contaminate the optical measuring track. In addition, the patented autocalibration process compensates the effects of aging, even without fresh air being introduced, thereby ensuring outstanding long-term stability.

The probes ensure a healthy indoor climate and the optimal well-being of the occupants while at the same time ensuring significant energy savings potential as required by EU standards and regulations such as the "Energieeinspar-verordnung" (EnEV) (Energy Saving Ordinance). Measuring ranges can extend from 0 to 2000/5000/10000...

Hygrometric measuring probes and hygrostats The special properties of hygroscopic fibers are used in hygrometric measuring probes and hydrostats to determine the relative air humidity. Due to a special preparation, the hair measuring element is capable of absorbing moisture. The change in length of this element is the externally measurable effect that is used to determine the prevailing air humidity.

Humidity measurement Capacitive measuring probes CO2 measuring probes Hygrometric measuring probes and hygrostats Wireless measured value transmission Hygrometric humidity transducers are suitable for both air conditioning applications and humidity measurements in industrial applications. The main advantage they offer is the highly water resistant sensing element. Another advantage is zero voltage operation for device versions with a passive output or for hygrostats with a switching output.

Sender – JUMO Wtrans E01 Wireless measured value transmission In buildings, the measurement of parameters such as air humidity and temperature often requires that cables are laid, which is cost and time intensive. This installation work can be reduced to a minimum by using wireless data transmission. Here, the JUMO Wtrans series offers an effective and cost-efficient alternative to conventional cabled measuring probes. The measured value is initially transmitted to the JUMO Wtrans receiver. From there, the signal can be forwarded in either digital or analog form for further processing to various...
