What is a DP transmitter? Differential pressure is represented by “DP”. The difference in pressure between two points in a process is measured by a DP transmitter, which then translates the data into a standard output signal (often 4-20 mA) for processing or transmission to a control system. DP transmitters generally include two pressure sensing …

What is an industrial thermometer? The gas-actuated, bimetal, or expansion principle is used in the operation of temperature gauges. They have a measurement range of -200 to +700 °C. Moreover, all instruments can be used in thermowell. The thermal condition of a homogeneous substance is measured by thermometers. The measuring system and the body that …
Vibration Oscillating movement around equilibrium position is called as vibration. Vibration measurement is used to check electric motors, turbines or bearings health and resonance. The dynamics of the machine, such as the alignment and balance of the spinning elements, are what cause vibrations in all rotating machines. Monitoring vibration amplitude at specific frequencies can reveal …
