Smoke Detector is a tool for detecting smoke that arises from sources of fire. Smoke involves the thermal release of large quantities of solid and liquid particles into the surrounding atmosphere. These particles that are suspended in the air are termed aerosols. The aerosol…
Why to use Pyrometers or non-contacting type? Non-contacting temperature meter or Pyrometers are used to measure temperature without any physical contact with temperature body. In many industrial application with a higher temperature range, where many other temperature meters and human can’t reach…
Resistance Temperature Detectors (RTD) are temperature measuring transducers used in industrial applications. RTDs are simple in construction with higher accuracy and repeatability and which are used in the applications below 600°C. Principle: As the name suggests the RTDs are temperature sensitive resistors….
A thermistor is a semiconductor device formed from metal oxides. thermistors are used in many applications requiring information about process equipment for alarming and indication purposes. Principle: The principle of temperature measurement with a thermistor is that its resistance changes with temperature. Most…
What is thermocouple? A thermocouple is an active transducer which directly converts thermal energy into electrical energy. It is a simple device made by joining to dissimilar metals or semiconductor forming a junction. It produces a voltage when the temperature at the junction…
IN industries temperature is a major physical quantity . there are different methods of temperature measurement in industries. The different methods of temperature measurement are: 1. Mechanical 2. Electrical. 1.Mechanical methods: Mercury in…
RTD transmitter Calibrating In industries temperature is a major physical quantity that has to be monitored and controlled.In this session we are discussing about calibration of RTD transmitter. Both RTDs and thermocouples are used for process temperature measurements. Equipments needed Transmitter 24VDC…
