PT100 Sensor | Thermocouple Head | -200 to 420°C RTD Probe

This stainless steel RTD PT100 temperature sensor gives exact temperature data for factory systems. The PT100 sensor is accurate and stable, working from -200°C to 420°C. It has a 3-wire build and a terminal head to protect the connection. Features and Benefits - 304 stainless steel probe - Handles corrosion and moisture well. This makes the waterproof PT100 sensor good for tough conditions. - PT100 Class A platinum element - Reads temperatures more accurately and consistently than most thermocouples in its range. - Standard 1/2" NPT thread - Installs easily into existing fittings, tanks, or thermowells. - Wide operating range - Measures from -200°C to 420°C. This covers uses from very cold cryogenics to medium-heat factory work. Applications - Industrial process control - Check temperatures in pipes, vats, and machines. This keeps operations safe and products consistent. - HVAC and refrigeration - Get correct temperature readings for managing big climate control and cold storage systems. - Laboratory and R&D - Put it into test benches and science gear. Accurate thermal data is very important for experiments there. Safety & Preparation Before installing or testing any precision sensor, ensure the power to the system is completely off to prevent electrical hazards. This PT100 sensor is designed for temperature measurement within a range of -200 to 420°C. Always wear appropriate personal protective equipment, such as safety glasses and gloves, especially when handling stainless steel components. Verify that the thread size of 1/2 inch is compatible with your existing equipment to ensure a secure and accurate fit. No battery is included or required for the operation of this RTD probe. Identify standard RTD Values An RTD sensor, or Resistance Temperature Detector, is a type of temperature sensor probe that measures temperature by correlating resistance with temperature. This specific product is an RTD PT100 sensor, meaning it has a resistance of 100 ohms at 0°C. Understanding this baseline is crucial when checking your RTD sensor. The temperature range for this particular PT100 sensor is from -200 to 420°C. These values are fundamental for calibrating or troubleshooting your temperature measurement system and connecting to a controller. How to Test by Wire Configuration Testing an RTD sensor involves measuring its resistance and comparing it to expected values for a given temperature. The accuracy of this measurement depends significantly on the wiring configuration. This PT100 sensor features a terminal head, which simplifies wiring connections. The goal is to accurately measure the resistance of the sensing element itself, minimising the impact of lead wire resistance. Different wiring configurations, such as 2-wire and 3-wire, address this challenge in varying ways.
