U.S. Sensor's thin film platinum RTDs (Pt-RTD) consist of a passivated thin film platinum element deposited on a ceramic substrate. Thin film Pt-RTDs provide cost advantages when compared to wirewound Pt-RTDs. Read More
The construction of a thin film RTD is simple. A thin layer of resistive material is first deposited on a ceramic substrate. A pattern is etched onto the sensor to serve as an electrical circuit which is trimmed to produce the desired resistance. Lead wires are then attached to the element and the whole assembly is coated with a thin layer of glass.
A platinum type RTD, Pt-RTD exhibits a nearly linear temperature-resistance curve, as well as very high stability, repeatability, and accuracy over a very wide temperature range. This makes it highly suitable for applications in extreme temperature conditions. Typical U.S. Sensor Pt-RTDs operate as low as -50°C and as high as +500°C, though higher temperature ratings are available via special order.
The thin film construction of our platinum RTD elements result in a smaller size compared to wire-wound RTDs. This gives them the advantage of having a fast response time, low thermal mass, high vibration resistance, high thermal shock resistance, and a small footprint.
U.S. Sensor also offers a wide selection of RTD probe styles available in a variety of housing sizes and materials, including plastic, stainless steel, aluminum, and copper. The precise, nearly linear temperature-resistance coefficient of U.S. Sensor RTDs makes them ideal in applications of extremely low and high temperatures. Platinum and nickel type RTDs are available.
