Series regulators are the more common form; they are more efficient than shunt designs. The series regulator works by providing a path from the supply voltage to the load through a variable resistance, usually a transistor (in this role it is usually termed the series pass transistor); it is in the "top half" of the voltage divider - the bottom half being the load.
Some voltage-regulator tubes contained small amounts of radionuclides to produce a more reliable ionization. [1] The Corona VR tube is a high-voltage version that is filled with hydrogen at close to atmospheric pressure, and is designed for voltages ranging from 400 V to 30 kV at tens of microamperes.
Two stage regulators may have two safety valves, so that if there is any excess pressure between stages due to a leak at the first stage valve seat the rising pressure will not overload the structure and cause an explosion. [citation needed] An unbalanced single stage regulator may need frequent adjustment.
Globe control valve with the pneumatic actuator and smart positioner. The loop current and stem travel are displayed. Control valves are normally fitted with actuators and positioners.
Energy regulator can refer to: Energy market regulator: see list of energy regulatory bodies; Infinite switch, a type of variable electrical heating element
A relief valve DN25 on cooling water pipe from heat exchanger Schematic diagram of a conventional spring-loaded pressure relief valve. A relief valve or pressure relief valve (PRV) is a type of safety valve used to control or limit the pressure in a system; excessive pressure might otherwise build up and create a process upset, instrument or equipment failure, explosion, or fire.
A regulator lever is often fitted, which can be used to alter the free length of the spring and thereby adjust the rate of the timepiece. The balance spring is a fine spiral or helical torsion spring used in mechanical watches , alarm clocks , kitchen timers , marine chronometers , and other timekeeping mechanisms to control the rate of ...
A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
