Why Miniaturize? The ideal detector should be as precise as you want and infinitely fast, but close to zero in price and size. We will show in the following text first of all what it is possible to achieve today regarding size. Due to the ever-increasing intensive use of high-performance electronic machine controls, a larger concentration of sensors can be observed. This should not, if possible, oblige the machine manufacturer to modify the mechanics just to provide space for detectors, it would be in fact illogical that the use of detectors makes the mechanics bulkier, therefore more expensive and even possibly less effective. This automatically results in the requirement for smaller and smaller detectors. This particularly concerns the proximity detectors used in large quantities, which we will deal with in the following text. Products & Services
Heat detectors are fire detection devices that sense heat produced by combustion. Heat detectors can trigger an alarm when they detect rapid temperature rise or reach a preset temperature.
Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance.
Inductive proximity sensors detect the presence or absence of an object using a critical distance.
Thermal imagers detect heat patterns in the infrared wavelength (1 micron to 100 micron) spectrum.
Gas chromatography detectors (GC detectors) identify solutes as they exit the chromatographic column. A chromatogram is generated plotting the signal versus time.
