How to measure humidity in an environmental test chamber

Environmental test chamber refers to equipment that can simulate environmental factors, mainly refers to equipment such as temperature, humidity, light, rain, sand, etc.. Among them, the equipment that needs to control humidity is the constant temperature and humidity test chamber. The humidity in the environmental test chamber can be controlled autonomously in a certain range. For example, the ...

Moisture measurement with M-Sens 2 - Case Study

Application An energy provider burns biomass (waste wood), to produce electricity and heat. The biomass is delivered and stored in a self contained storage area. Following the separation process of removing (ferrous, non ferrous-metals), the remaining wood is conveyed to a fluidized-bed system, where it is burnt. The steam generated produces electricity via a turbine. During the process of ...

Sonic temperature significance and limitations

The ATI sonic thermometer measures temperature from transit times t1 and t2 measured along the vertical path of the anemometer's probe. They are the times taken by sound pulses to traverse the 15-cm acoustic path in opposite directions; (these same transit times are used also for computing the vertical wind component). The instrument exploits the strong dependence that exists between the speed ...

Can Humidity Interference Affect PID Results?

A common frequently asked question is “can humidity interference affect my PID detector results?” Like many sensors and measurement instrumentation, traditional PIDs can indeed be affected by the environmental conditions i.e. dust, dirt and in particular, humidity. The major producers of oil & gas are located in the Gulf States and in or close to the Gulf of Mexico, which are ...

The Measurement and Prediction of Conditions within Indoor Microenvironments

Biocontaminants, such as dust mites and microfungi, can live in building habitats with a spatial scale of only a few millimetres. With the recent development of very small size microchip-based sensors, it is now practicable to measure the humidity at different locations within these microenvironments. In the laboratory study described here, sensors were used to measure the conditions in a number ...

Smart Sensor Benefits, Part 1

Simple analog sensors require the host device to perform a number of calculations to correctly scale the inputs, check for errors, and convert to usable measurement units. Similarly, sensor measurements are typically averaged over several seconds, minutes, or hours in order to present useful measurements of conditions and trends. Instantaneous measurements can be misleading or jump around too ...

Moisture measurement with M-Sens 2 Sensor selection with Easy-Tester - Case Study

Application During the process of cement production cement powder is burnt to clinker. This process takes place in a kiln. For the operation of this kiln different combustibles are used, amongst others sewage sludge. The heating value of sewage sludge depends on its degree of dryness. Sewage sludge normally has a high moisture content when it is delivered to cement plants, therefore it must be ...

Which influence does indoor climate have on the success of a trade show?

Trade shows provide promising opportunities for both exhibitors and visitors. While companies use the events for product presentations and customer acquisitions, visitors can learn about the latest industry developments. However, the benefits of trade shows can only be fully exploited if the local climatic conditions are optimally controlled… Why are trade show events so popular with ...

Performance characteristics of a Thin-film aluminum oxide humidity sensor - Case Study

Summary A laboratory study was made of the performance of a miniature-size, thin-film aluminum oxide humidily sensor over a range of ambient temperatures from 0°C to 40°C and encompassing humidities from 40 to 78,000 parts per million by volume (ppm-v). Hysteresis and temperature effects of the sensors were obtained from tests performed at ambient temperatures 40°C, 25°C and ...

New technologies for measuring the humidity of biomass

Methods applicable to a great variety of solid biofuels In recent years, systems have sprung up which use near infrared X-ray (NIR) spectroscopy, radio frequency (RF) and microwave spectroscopy as alternatives to the traditional method of measuring humidity by weight difference in the fuel burner. What these methods have in common is that they can be used for a great variety of solid biofuels, ...

Effects of high humidity on photoionisation detectors (PIDs)

There are a few important issues to look out for when choosing an instrument. Like many sensors and measurement instrumentation, traditional PIDs can be affected by the adverse environmental conditions such as those found at fire scenes i.e. dirt, water and humidity. The situation in the immediate aftermath of a fire is therefore not ideal and in particular the presence of high humidity can ...

GENAQ: Water from the air

Do you know the working principle of GENAQ atmospheric generators? Its operation is similar to the rain process, that is, our generators extract water from the humidity of the air by condensation. We go one step beyond what nature generates in the form of rain making the water drinkable thanks to a specific water treatment, so that it is optimal for human consumption. All this procedure is ...

A sewer ventilation model applying conservation of momentum

The work presented herein was completed in an effort to characterize the forces influencing ventilation in gravity sewers and to develop a mathematical model, based on conservation of momentum, capable of accounting for friction at the headspace/pipe interface, drag at the air/water interface, and buoyancy caused by air density differences between a sewer headspace and ambient. Experiments were ...
