What are RTD temperature sensors?

RTDs or Resistance Temperature Detectors, are temperature sensors that contain a resistor that changes resistance value as its temperature changes. The most popular RTD is the Pt100. They have been used for many years to measure temperature in laboratory and industrial processes, and have developed a reputation for accuracy, repeatability, and stability.

Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is usually quite fragile, so it is often placed inside a sheathed probe to protect it...


What is a Signal Conditioner?

What is a Signal Conditioner?

A signal conditioner is a device that converts one type of electronic signal into a another type of signal. Its primary use is to convert a signal that may be difficult to read by conventional instrumentation into a more easily read format. In performing this conversion a number of functions may take place.

Signal conditioning is a vital process performed within the Data Acquisition System. It involves the manipulation of the analog signal output from the sensors to prepare it for the next stage of processing. Signal conditioning amplifies and converts the signals from the sensors or...
