How to specify a thermowell?

Temperature measurement and control is an important factor in all process industries and in power plants environments of higher temperature and higher pressure.           The thermowell allows the temperature sensor Thermocouple and RTD to remove easily from the process environment for the purpose of calibration in case of measurement error, or replacement in case of …

What is a Resistance temperature detector and what are its types?

What is a Resistance temperature detector? The resistance temperature detector is basically a resistance thermometer, and it is used to measure the temperature. RTDs are replacing thermocouples due to their better accuracy and repeatability. The RTD works on the principle that the resistance of the RTD element would vary with the change in temperature. RTDs …

What is a thermistor?

A thermistor is a resistor and its resistance would vary if its temperature changes, so basically a thermistor can be described as a temperature-sensitive electrical resistor. The thermistor is highly sensitive to temperature, it is a class of metal oxide. By using a thermistor we can do accurate temperature measurement and it is inexpensive too. …

Type K Thermocouple

Type K thermocouple: Type K thermocouple is the most commonly used thermocouple type, because it has the widest operating temperature range. Leg Metal: Chromel, Alumel Temperature Range: -270°C to 1260°C Melting Point: 2550°F Tolerance: +/-15K between -40°C to 375°C Positive leg: Non magnetic, chromel Negative leg: Magnetic, Alumel Colour coding for K type thermocouple: Why …

What is temperature Scanner? Applications of temperature scanner:

It is important to monitor the temperature in separate areas in a device or in a manufacturing system and offer a prevalent warning whenever these areas reach their respective boundaries. Having one electronic device deployed for each area will be costly and unwieldy. Instead, having one electronic device intended to detect temperatures in distinct areas …
