RTD's

RTDs (Resistance Temperature Detectors) - are temperature sensors that have a resistor inside that changes resistance value as its surrounding temperature changes.RTDs are being used for many years to measure temperature in industrial processes, labs and have developed a reputation for stability, repeatability and accuracy.

RTD elements mostly consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is mostly somewhat fragile, so it is often placed inside a sheathed probe for its own protection. The RTD element is made from a very pure material whose resistance at various temperatures has been known or documented. The material has this predictable change, in resistance which is proportional to the change in temperature; it is this predictable change that is used to determine temperature.

RTD sensors are generally chosen over our thermocouples in applications which require a higher accuracy and higher repeatability of temperature measurements. Due to their design, our RTDs are also easier to install and calibrate.
