What is this?PT100 thermocouple sensors are used for temperature measurement and control. Stainless Steel temperature controller temperature sensor can be used to measure temperature and are widely used as temperature sensors for temperature measuring instruments. Mainly used for temperature measurement of science use, industrial use, engine, also used in families, etc.What will I get?Temperature sensor, is in size of : 5mm x 100mm/0.2 inch x 4 inch(D*L) probe size, 2m/6.6ft cable length, -50 to 500°C(-58 to 932°F) measuring temperature, the probe is made of stainless steel, mounting thread, NPT1/2 inch, 3-wire connection, positive red, negative blue.In the package of: 1pcs x Temperature sensorIs there any advantages of the product?PT100 thermocouple is mainly used for low temperature measurement with high accuracy. PT100 thermocouple sensors, with high precision, accurate measurement, fast response time, can quickly measure temperature; Thermocouples can be used for different types of temperature measuring equipment and instruments, such as temperature controllers, digital thermocouple thermometer, hvac digital gauges, lab digital thermometers, etc.How to use it?Steps of installation: In order to reduce the measurement error, the thermocouple should have enough insertion depth. No additional power supply is required for thermocouple measurement, which is very convenient to useWhat should I notice?When selecting a thermocouple, the measured temperature range should be taken into consideration. Due to different usage environments, it can be used for a long time at temperatures below 400°C, but can only be used for a short time at temperatures between 400-500°C, otherwise it will affect product life.
