Magnetic proximity sensors include devices that work on inductive, variable reluctance, magneto resistive or Hall effect principles. Proximity sensors detect the presence or absence of an object using a critical distance.
Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches.
