  • Increasing Power to Overcome Sound Attenuating Vapors or Poor Targets and Avoiding False Echoes When Using Ultrasonic Sensors
    Ultrasonic Sensors are often used to measure the level of liquid and solid materials. They are reliable and cost effective instruments for these applications. In operation the sensor is mounted over the surface of the liquid or solid. To determine the distance to the material, it transmits a sound
  • All From One Mold - Optical, Ultra Sound, Inductive and Capacitive Sensors
    A uniform casing design, the same calibration and start up, as well as standardized mounting - and alignment fixtures are the features of this series of sensors, which encompasses many different technologies. This results in a multitude of advantages with construction of machines and equipment
  • An Overview of Proximity Sensors
    Proximity sensors detect the presence or absence of objects using electromagnetic fields, light and sound. There are many types, each suited to specific applications and environments. Here's a look at the most popular proximity-sensing technologies.
  • Ultrasonic Sensors, The Silent Laborers
    During operation the transducer alternates continuously between transmitting and receiving. If the transmitted switch packets encounter an object the sound is reflected and a small part of the energy is reflected back to the sensor, respectively the transducer. The output of the sensor reacts after
  • Delay Time Measurement with Ultrasonic Sensors
    Many industrial ultrasonic sensors are based on the delay time measurement. As has been mentioned in the introduction, the "measurement representation" thereby is the propagation velocity of the sound in the air, which is 330 m/s under normal conditions. The sensors utilized for these functions
  • Application: Car Hood Position Alarm Sensor (.pdf)
    The most costly items of an automobile are under the hood of the car. Thieves, once the hood of the car is open, can unfasten the engine, battery, etc. very quickly. Having a sensor that is tied into the vehicle on-board computer could sound an alarm or the car horn.
  • Application: In-The-Canal Hearing Aids - Reed Sensor
    Hearing aids are just that. They allow a person. to better hear sounds and speech. Strange as it may seem to those that hear perfectly, people with hearing disabilities don't like to advertise. their malady. Many of the hearing aids previously. have been worn external to the ear acting
  • Six Reasons to Consider Ceramic Metal Oxide Moisture Sensors for Your Process
    Metal oxide moisture sensors have been on the market for years. Since their introduction in the 1960s, there have been many developments in trace moisture sensing technologies for industrial processes. And let's face it - many of these appear to be a lot more exciting than the humble dew-point
