Sensing technologies

Following is a list of suppliers for level sensing technologies. 

Therefore any attempt to model the spatial occurrence and fate of chemicals in the environment will require an appropriate choice of all the factors discussed above, which have a definite influence on the behavior of the chemicals considered. Figure 2 summarizes some of the most relevant. It is worth mentioning that the availability of spatial data sets has been greatly enhanced by the current progress achieved on remote sensing technologies [57, 58]. 

Several hydrogen sensing technologies and detection schemes were discussed in this chapter. The success of each technology is determined by its performance in the target application domain. 

Reed relais are an example of well-established distance sensing technology. They are used in millions of appliance units and are described in Chapter 5.2. 

Similar technology is also being used in induction hotplates and radiant heating elements and in the silicon nitride hotplates currently under development and which are characterized by an excellent heat transfer between heat source, sensor and saucepan. Gas hotplates could also be provided with the latest in domestic temperature sensing technology by fitting them with electric temperature control circuitry. 

There are two product categories of displacement sensing technology. Whenever the moving target is mechanically connected to a sensor, it is referred to as a contact displacement sensor. The physical principles adapted for contact displacement sensors are primarily ... 

The process of detection can be performed by using different sensing technologies and different sensors. 

Fluorescence is a well-observed phenomenon characteristic of many materials and the different forms of their aggregation. Meantime the vast majority of studies on fluorescence have been on small organic molecules in liquid solutions. Parameters of their emission (intensity, lifetime, anisotropy, and positions of excitation and emission spectra) were found to be extremely sensitive to intermolecular interactions [1], which justifies their extensive application in various sensing technologies...
