PT100 Sensor | -50 to 260°C Range | 1M Heat-Resistant Cable

This waterproof PT100/PT1000 temperature sensor provides steady readings in wet or tough conditions. You can pick a PT100 or PT1000 element. This lets it match your equipment. The stainless steel probe and heat-resistant silicone cable make it a good choice for different jobs. Features and Benefits - PT100 or PT1000 choices - A PT100 sensor is a common industry standard. A PT1000 often works better for battery-powered devices or 2-wire setups. - Rust-resistant probe - The 304 stainless steel temperature probe is safe for liquids. This includes water, wort for brewing, or aquarium tanks. - Broad operating range - It works from -50°C to 260°C. It handles everything from freezing to boiling temperatures. - Submersible design - The probe is completely sealed against water. You can leave it submerged for ongoing monitoring. Applications - Homebrewing - It accurately monitors your mash or boil temperature. This helps with consistent batches. - Aquariums and hydroponics - It keeps water temperatures steady. This helps fish and plant health. - Climate control systems - Use it as a waterproof RTD sensor. It works for outdoor temperature monitoring or in cooling systems. Safety & Preparation An RTD (Resistance Temperature Detector) sensor, like this PT100, is a precision sensor used to measure temperature. Before handling any electrical components, always ensure power is disconnected to prevent electric shock. When working with the PT100 sensor, particularly its 1M heat-resistant cable, avoid sharp bends or excessive pulling that could damage the internal wiring. The stainless steel probe is robust but should be protected from impact. Always verify the temperature range of -50 to 260°C is suitable for your application before installation. Identify standard RTD Values To check an RTD sensor, you need to understand its standard resistance values at specific temperatures. For a PT100 sensor, its resistance is 100 ohms at 0°C. This product is a PT100 sensor. As temperature increases, the resistance of the sensor also increases in a predictable manner. Refer to a standard PT100 resistance table for precise values across the -50 to 260°C range. These tables are essential for calibrating a controller or verifying the sensor's accuracy. How to Test by Wire Configuration Testing an RTD sensor involves measuring its resistance. The method varies depending on the wire configuration. This PT100 sensor has a 2-wire configuration. A multimeter is typically used for these measurements. Ensure the multimeter is set to measure resistance (ohms). A. 2-Wire RTD For a 2-wire RTD, like this PT100 sensor, connect the multimeter leads to the two wires of the sensor. The measured resistance will include both the sensor's resistance and the resistance of the 1M heat-resistant cable. For accurate readings, it is advisable to account for the cable resistance, especially with longer cable lengths. Compare the measured resistance to the standard PT100 resistance table for the ambient temperature. B. 3-Wire RTD (Most Common) While this specific PT100 sensor is 2-wire, 3-wire RTDs are common for improved accuracy. A 3-wire RTD has two wires connected to one end of the sensing element and one wire connected to the other. To test, measure the resistance between the two wires that go to the same end of the element to get the lead wire resistance. Then, measure between one of those wires and the third wire to get the total resistance including the sensor. Subtract the lead wire resistance to find the sensor's true resistance.
