  • What is a Resistance Temperature Detector (RTD)?
    element is made from a pure material whose resistance at various temperatures has been documented. The material has a predictable change in resistance as the temperature changes; it is this predictable change that is used to determine temperature. Common Resistance Materials for RTDs: Platinum (most
  • Calibration & Maintenance of Smart Transmitters
    Brief tutorial on how today's smart transmitters work and why/how they should be calibrated. Martel Electronics Process Calibrators Blog. Calibration technology starts here ... The Calibration Maintenance of Smart Transmitters - I. May 10th, 2011. This is the first of several articles

  • Real-World Testing of Industrial Pressure Transmitters
    exhaustive testing to make sure they are water resistant, shock-resistant, and able to handle environments and temperatures ranging from frozen tundra to the burning sands of the Sahara. Pressure transmitters and transducers need to withstand extreme conditions to provide reliable performance. Real-World
  • RTD Resistance Ratio
    of the thermometer at some temperature is measured as 25.84327 ohms. What is the temperature? The resistance ratio is found as follows: RR=RT/R0 25.84327 / 25.51548. If the table is given in 1�C increments, the precision of the mathematical computations for determining the measurement temperatures
  • Resistance Temperature Detectors: Theory and Standards
    With these general guidelines to the basic function, performance, and recognized standards for RTD's, anyone can specify the right device for the application. RTD Sensors. Resistance Temperature Detectors: Theory and Standards With these general guidelines to the basic function, performance
  • SIL Compliant Temperature Measuring Points
    is off, internal and external temperatures are the same". For this reason, this is an especially dangerous and non-detectable fault: ldu. In a thermocouple, all the influences of connecting cables, connection terminals and connectors are compensated. All resistance changes are detected
  • New, more robust RTD temperature sensor
    To prolong the life of marine diesel and gas engines, it's important to monitor and control exhaust gas temperatures - and this requires an accurate temperature sensor. Based on two types of sensor technology, temperature sensors either use a Resistance Temperature Detector (RTD) with PT100 thin
  • Wireless Devices for Temperature Monitoring (.pdf)
    a closer look. As a. bonus, most of the devices discussed below also work with humidity and barometric pressure sensors. Transmitter Options. The temperature sensors most commonly in use are thermocouples and RTDs (resistance temperature. detectors). The various types of transmitting units available wil
  • Temperature Monitoring Starts With an Analysis of Your Application
    , petrochemical, and quality control applications where you need exact readings. Twin-Temp Thermometers combine a bimetal thermometer and thermocouple or resistance temperature detector (RTD) electrical output to provide quick and easy readability at the point of process as well as electronic data acquisition
