Surface PT100 Sensor | Waterproof 3-Wire | 5m Cable Length Option

This stainless steel PT100 sensor reads temperatures directly from a surface. It's a pasted-type sensor with a strong adhesive back. You can stick it right onto pipes, tanks, or machinery. It's a simple way to check temperature without drilling holes. Features and Benefits - Adhesive Backing - It installs in seconds on flat or curved surfaces. This ensures good thermal contact for accurate data. - 3-Wire RTD Configuration - It accounts for cable resistance. This gives more precise measurements than 2-wire sensors, especially with long cables. - Waterproof Probe and Cable - The sealed stainless steel housing and PTFE-insulated wire allow use in wet or damp environments. - Class A Accuracy - It measures temperatures from -50°C to 200°C. It has a high degree of precision for industrial needs. Applications - It checks the temperature of pipes in HVAC and plumbing systems. - It monitors the surface temperature of motors or electronic enclosures. - It attaches to vessels and tanks to track the temperature of their contents. Safety & Preparation Always ensure power is disconnected to any associated equipment before working with sensors or wiring. This Surface PT100 Sensor is a precision sensor designed for accurate temperature measurement. It is a 3-wire configuration. The sensor is waterproof and features a stainless steel material construction. It does not include a battery and is available with cable lengths of 1m, 2m, 3m, or 5m. Identify standard RTD Values An RTD (Resistance Temperature Detector) sensor, like this PT100, measures temperature by correlating resistance with temperature. A PT100 sensor has a resistance of 100 ohms at 0°C. As the temperature increases, so does the resistance. For accurate readings, ensure your controller or measurement device is calibrated for PT100 values. Consult your controller's manual for its specific input range. How to Test by Wire Configuration Testing your RTD sensor ensures it is functioning correctly and provides accurate readings to your controller. This Surface PT100 Sensor is a 3-wire configuration. Understanding the different wiring methods is crucial for proper installation and troubleshooting. This sensor is designed for pasted surface end mounting. A. 2-Wire RTD A 2-wire RTD uses two wires to connect the sensor to the controller. One wire carries the excitation current, and the other returns the signal. The resistance measured includes both the sensor resistance and the resistance of the lead wires. This can introduce inaccuracies, especially with longer cable lengths. This product is a 3-wire configuration, not 2-wire. B. 3-Wire RTD (Most Common) This Surface PT100 Sensor is a 3-wire RTD. This configuration is the most common for industrial applications because it compensates for lead wire resistance. Two wires are used to measure the sensor resistance, and a third wire measures the resistance of one of the lead wires. The controller then subtracts this lead wire resistance from the total, providing a more accurate temperature reading.
