.jpg) Pneumatic control devices include instruments, valves, positioners, transducers, transmitters and Filter, Regulator and Lubricator assemblies. Regulators are designed for use in laboratory environments, remote loading of pneumatic devices, speed changers and other general purpose applications. Transducers accept a variety of electrical input signals and convert them to proportional pneumatic output signals. A typical input is 4-20 mA DC and and an output of 3-15 PSIG. Filter, regulator, lubricator (FRL) assemblies are pre-packaged or modular units consisting of air filters, regulators, lubricators, and gauges. FRL assemblies are mainly used in point of use applications. |
