Most RTD elements consist of a length of fine coiled wire wrapped around a ceramic or glass core. The element is typically relatively fragile, so it is generally installed inside a sheath to protect it. The RTD element is constructed from a pure material, the resistance of which, at various temperatures, has been documented by various international standards institutes. The material has a predictable change in resistance as the temperature varies; it is this change that is used to determine temperature. Resistance thermometer. Resistance thermometers, also called resistance temperature detectors (RTDs), are sensors used to measure temperature by correlating the resistance of the RTD element with temperature.

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. The RTD element is made from a pure material, typically platinum, nickel or copper. The material has a predictable change in resistance as the temperature changes and it is this predictable change that is used to determine temperature. They are slowly replacing the use of thermocouples in many industrial applications below 600 °C, due to higher accuracy and repeatability.[1][2] [edit] JUMO eTRON T - Digital Thermostat.

PT100 sensors (Platinum Resistance Thermometers or RTD sensors) Platinum resistance thermometers (PRTs) offer excellent accuracy over a wide temperature range (from -200 to +850 °C).

PT100 sensors (Platinum Resistance Thermometers or RTD sensors)

Standard Sensors are are available from many manufacturers with various accuracy specifications and numerous packaging options to suit most applications. Unlike thermocouples, it is not necessary to use special cables to connect to the sensor. The principle of operation is to measure the resistance of a platinum element. The most common type (PT100) has a resistance of 100 ohms at 0 °C and 138.4 ohms at 100 °C. There are also PT1000 sensors that have a resistance of 1000 ohms at 0 °C. The relationship between temperature and resistance is approximately linear over a small temperature range: for example, if you assume that it is linear over the 0 to 100 °C range, the error at 50 °C is 0.4 °C. This linearisation is done automatically, in software, when using Pico signal conditioners. CONTROL TEMP DGTL VOLTAGE OUT - E5CS-Q1KJX-F.

General Purpose / Low–Cost PT100 Probes. What is a motor thermistor. Engine temperature sensor. Engine Temperature Sensor - Bimmerforums - The Ultimate BMW Forum. Bosch - Oxygen Sensors. Can anyone tell me what does an Engine Temperature Sensor do? and what if the Sensor is malfunctioned. ECT (Engine Coolant Temperature) Sensor. An ECT sensor, or Engine Coolant Temperature Sensor is a sensor that is screwed into the engine's block or cylinder head and is used to determine the temperature of the engine coolant.

The ECT sensor is basically a thermistor that changes resistance with temperature. When the ECT (engine coolant temperature) is high (hotter), the resistence is low, and when the ECT is low (cooler) the resistence is high. This resistance reading is sent to the vehicle's PCM/ECM (car's onboard computer) and is or can be used to activate emission controls or turn the engine's cooling fan on. The ECT sensor is usually a two wire sensor that uses a 5 volt reference from the PCM with a ground signal back to the PCM. In general terms if the ECT reading is cold the reading could be less than 0.5 volts (on the ground signal) and when the engine is hot the reading could be around 4 volts.

Here is a photo of one ECT sensor: This informative video provides information on testing and replacing automotive ECT sensors.
