Thermocouples are available in various types of calibrations ranges, it is important to carefully select the right thermocouple for our application such as oxidizing, and reducing atmospheres taken into consideration. In the table below are listed the main types of thermocouples: Thermocouple type Positive Element, Negative Element Typical Temperature Range Standard Error Line Type… Read More Types of thermocouples and their uses in various environments.
Whichever type of control valve is selected, they all have common features such as: Surfaces that form a seal to seal the passage. In control valves usually, there is a fixed seal and a movable seal. Control valves usually consist of a stem that allows a movable seat to move. A hand-wheel or similar devices… Read More Control Valves and its categories.
Every measuring instrument or device requires calibration at periodic intervals, which is part of preventive maintenance (PM). It is because, every instrument or device undergoes drift in calibration with time. Let us discuss As-found data and As-left data in this article. In calibration sheet with “As-found” data is most important because it will determine the… Read More What is “As-Found” and “As-Left” calibration data?
The signal generator is an electronic device that induces repetition and non-repetition of analog or digital signals. The signal generator is widely used in troubleshooting, signal tracing, testing, amplifier response tuning, and radio and TV circuit alignment. The signal generator has a built-in modulation property. Amplitude and modulation properties are very common in signal generators.… Read More Signal Generator and Types
Batteries are accumulators that convert stored chemical energy into electrical energy and are an essential device in isolated, self-consumption installations. Principle of Battery The basic principle of a battery comprises the oxidation-reduction (redox) reactions of particular chemical substances. One chemical substance of which loses electrons (is oxidized) while the other gains electrons (is reduced), being… Read More Types of Batteries and their important Characteristics.
