Introduction The secondary electronics of a transmitter amplify and condition the weak electrical signals generated by the sensor, so that the signals can be sent...
Introduction All the targets radiate energy in the infrared spectrum. The hotter the target, the more energy it radiates. Very hot targets radiate in both...
Introduction A pyrometer, or radiation thermometer, is a non-contact instrument that detects the temperature of an object’s surface by measuring the temperature of the electromagnetic...
Why use square root extractor for DP transmitter? The DP flowmeters measure the differential pressure across the constrictions made in the flow channel. The differential...
Introduction In process plants, sudden release of hydrocarbon / self igniting fluids may develop rapidly into a fire. In such cases it is imperative that...
Introduction The infrared (IR) Gas detection method is based on the absorption of infrared radiation at specific wavelengths as it passes through a volume of...
Introduction Several detector designs exist for process gas chromatographs. The two most common are the flame ionization detector (FID) and the thermal conductivity detector (TCD)....
