Electronic and Pneumatic Controls
Pneumatic Systems comprise a huge number of technologies and integrations that use pressurized air to either power or drive them. In the case of pneumatic controls and instrumentation, pneumatics are used to communicate process variable commands to control valves. Pneumatic logic is used in many machine applications. While being explosion proof and intrinsically non-hazardous for dangerous areas such as in refineries and chemical plants, pneumatics are relatively easy to install and maintain since the signals are carried through simple low pressure tubes.
