A Resistance Temperature Detector is used to determine the temperature by measuring the resistance of an electrical wire. RTDs work on a basic correlation between metals and temperature. The resistance temperature detector uses the change in electrical resistance of the sensing element to determine it’s temperature.
Transition Joint Conventional Assembly RTD sensors are lightweight Built with rugged transition joints, this RTD sensor measures temperatures between -50°C and 250°C. It comes with rugged transition joint connections and compacted magnesium oxide (MgO), which protects the RTD assembly from vibrations and increases.
The RTD Probe–Plug and Jack Connector is constructed with a Stainless Steel case. The sensing element is embedded into the tip of the sheath. With the element located in the tip of the case this is the area that needs to be in contact with the process to obtain correct temperature measurement. Fittings associated with the probe designs are related to the mounting technique required by your application.
Spare Insert RTD is used as spare or replacement thermocouple element in existing RTD assembly with thermowell protection tubes. The mineral insulation structure enables flexibility & durability. It is available in various sheath diameter & sheath materials.
RTD for Skin / Surface Measurement is designed to measure the temperature of the pipe or tank surface. It is tied to the surface of the body to which temperature is to be measured through an insulating pad so that it collects temperature. Generally, they are used where rapid detection of temperature is required and there is no way to apply the immersive method of temperature measurement.
Multi point RTD are used to measure more than one temperature point through a single access point. The sensor has multiple temperatures input along the length of the sensor to calculate an accurate temperature profile. These sensors are mostly used in chemical and petroleum industries for temperature profiling of reactors, crackers, and liquefied gas in tanks.
