  • Resistive Temperature Detectors: Thermocouple Alternative for Precise, Repeatable Temperature Measurements
    wound and encapsulated. on a glass or ceramic bobbin (Figure 1). A second consists of a conductive film deposited. and encapsulated on an insulating substrate. Assemblies often include connectors, sheaths,. and handles. Principle of Operation. The resistance of most metals increases with temperature
  • Medical Device Link .
    tubes, and extensionwire circuits should be checked periodically. Inspection frequency depends on a number of factors, but once a month is usually sufficient. Both ceramic and metal protection tubes should be visually examined for excessive corrosion, wear, oxidation, or physical damage. Tubes
  • RTD Theory
    . The thin film style of RTD is probably the most popular design because of their rugged. design and low cost. The thin film element is manufactured by coating a small ceramic. chip with a very thin (.0001”) film of platinum and then laser cutting or chemical etching. a resistance path
  • Medical Device Link . The votes are in! Without even knowing it, the regular readers of EMDM have spent the past year selecting the 40 most useful and innovative products and services from hundreds of candidates. Each time they fill out a product inf
    . Ultrasonic transducers Constructed from piezocomposite ceramic-polymer layers, ultrasonic transducers maintain a strong balance between bandwidth and sensitivity. The transducers operate over frequencies that range from 200 kHz to 17 MHz. Units can be supplied as single elements or as linear

  • High Speed Fiber Optic Infrared Transmitter (.pdf)
    determines the field of view, a fiber optic tip probe for general purpose applications, and a. polymer bolt probe for immersion in polymer plastic flow, which is threaded so it can be inserted through a. pipe or chamber wall. In addition to the common metal housing, there is a ceramic housing for high
  • How To Select Instrumentation Sensors To Ensure Continued Performance
    . Implementing sensors equipped with innovative ceramic measuring cells provides over-pressure capabilities, drift performance and a rapid reaction time for high resistance to common sensor failures experienced with alternative technologies. Further, pressure sensors featuring IP69k-rated housing
