Resistance Temperature Detector
Resistance Temperature Detector Resistance temperature detector is also known as RTD. An RTD is a temperature measuring device that measures temperature when a resistance changes. It is a device made of platinum. RTD works on temperature and resistance relationship and RTD is a passive device. RTD consist of insulated copper wires and resistive elements. The temperature sensing element of an RTD is a resistive element. RTD is commanly known as resistance thermometer and is a commaly used thermometer to measure temperature. Benefits of RTD is high accuricy and high temperature range. The RTD sensing element is metal and when electrical resistance changes with temperature. There are two types of RTDs one is a thin film element and the other is a wire wound element. Thin Film RTD A thin film RTD is made of platinum film. A platinum film is known as a thin layer of resistive material and is formed on a ceramic substrate. Platinum thin film RTD is also known as Pt-RTD. Platinum thin film RT
