The core reason for the development of 4-20 mA was for 2 wire, loop powered instrumentation, where 3.5-3.6 mA is used for powering the instrument. Without a minimum 3.6 mA field instruments would not have any energy or power to run themselves! They'd be 3 or 4 wire devices with separate wiring for DC power.
1. Concentric: These plates are used for ideal liquid as well as gases and steam service. Concentric holes are present in these plates, thats why it is known as concentric orifice. 2. Segmental: This plate has hole in the form of segment of the circle. This plate is used for colloidal and sherry flow measurement. 3.

The actual movement of a bimetal is its flexivity with one end fixed, a straight bimetal strip deflects in proportion to its temperature, to the square of its length and inversely with its thickens. 3. Pressure Spring Thermometers: There are four classes of pressure spring thermometers. 1.
Both PLC and DCS support different types of programming languages. Functionality: PLCs are typically used to control and monitor specific types of processes or systems, while DCS is more versatile and can be used to control and monitor a wider range of processes and systems. Cost: PLCs are generally less expensive than DCS, …
A large scale (DCS substitute) PLC system has the controllers actually DISTRUBUTED more than they would be in a DCS. The control cabinets in a PLC system become wall-mounted panels or free-standing multi-door cabinets (typically) because the space requirements and mounting options for the PLCs are different (PLC-5 being an …
