  • Sensor Sense: IP ratings for sensors
    A classification system established by the International Electrotechnical Commission (IEC) rates how well enclosures and packages for electrical components seal against intrusion by foreign materials such as dust and moisture. Sensor ingress protection, a.k.a. IP, ratings detail how well sensors
  • LBA differential pressure sensors - high immunity to dust contamination
    In this application note First Sensors LBA differential pressure sensors are experimentally compared to other sensors which use the same (thermal-anemometer-based, non-membrane) sensing principle, where differential pressure is inferred from a gas flow through the sensor. With dust in the air flow
  • Proximity Sensors
    to detect, the upper switching range of these devices is about 50 Hz. Primary applications are in bulk-handling machines, level detectors, and package detection. One advantage of capacitive sensors is that they are unaffected by dust or opaque containers, allowing them to replace optical devices. A typical
  • Lufft VENTUS Ultrasonic Wind Sensor Proven for Offshore Operation
    The Lufft Ultrasonic Anemometer VENTUS-UMB successfully completed the test at the International Technical Inspection Agency TUEV SUED and now has the Protection Class IP68. This confirms officially that the sensor is one of a few Ultrasonic Anemometers, protected from infiltration of dust as well
  • Application Advantages of LBA Differential Pressure Sensors Due to Their Very High Pneumatic Impedance
    principle of inferring differential pressure from a thermal mass flow measurement. The LBA pressure sensors can achieve very high pneumatic impedances up to 200,000 Pa/(ml/s). This reduces the gas flow through the sensor to an absolute minimum and allows high immunity to dust contamination
  • IP Ratings for Proximity Sensors (.pdf)
    The International Electrotechnical Commission (IEC) established a classification system to rate the degree to which the enclosures of electrical components are sealed against the intrusion of foreign bodies such as dust and moisture.
  • Application: Intrinsically Safe Push Button Reed Sensor (.pdf)
    Many facilities, particularly manufacturing environments where dust particles or explosive atmospheres may exist, represent real challenges when it comes to electronic circuitry and switching contacts. Any type of arc can set off an explosion dramatically damaging the facility. Reed switches
  • Stainless steel for tight seals
    . This is especially true when the sensor sees high-pressure water spray as used for wash down. Because SS sensors are not made from separate pieces, there are no gaps for moisture, dust, or other elements to enter. So how does an SS sensor detect the desired target and not its own metal face? First, it uses
