use in pneumatic comparator used in automobile industry used in air suspension system used in pneumatic machines used for cleaning purpose
the difference between both are: Primary transducer:The Mechanical device which converts physical quantity to be measured into a mechanical signal. Secondary tranducer:The Electrical device which converts this mechanical signal to the electrical signal.
a pressure transmitter is a devise to measure the mechanical pressure and convert in to electrical signal it may be 4~20mA or 0~10V
in control technology an input would be a temperature or something of that nature derived from the process and an output would be a signal to control a control valve or actuator that effects the input signal.
Engineers are the ones that make the majority of a robot. Mechanical engineers build the parts, and software engineers create the programs. Electrical, pneumatic, industrial and hydraulic enngineers are all disciplines that are involved.
A current signal can be converted into a pneumatic signal using a current-to-pressure (I/P) transducer. The transducer converts the electrical current input into a corresponding pneumatic pressure output that can be used to operate pneumatic devices like cylinders and valves. This conversion allows for the control and automation of pneumatic systems using electrical signals.
current to preesure converter means....current signal to pneumatic signal...
to amplify the input pneumatic signal
the input signal is carried to CPU by having a binary numbers.
Transmission Media
Binary telephone signals.
That varies depending on the circuit technology used and function of the signal.
Duo binary encoding is nothing but any information either that continuous or discreate signal it will encoded in to binary in the form of set of two binary numbers. It is called as duo binary encoading
an encoder is used to convert the binary signals into analog signals. the binary signals are fed to encoder section. then these signals are get converted into its equivalent analog signals. Binary DAC.
A synchronous or asynchronous stream of signal consisting only of zero(no voltage) and one(position voltage) is called binary data stream. They may be bytestream, wordstream and so on. Sending unique binary pulses periodically create a binary digital signal. For example, you want to pass the number 346F5A through binary digital signal it will be 001101000110111101011010 Break it 0011-0100-0110-1111-0101-1010 you will find the binary equivalents of each digit. This example is very simple. Usually complex form of data are sent to and fro through data lines, be it the SATA cable of your hard drive, the USB port or the internet.
You sample the signal to get a number, base that number in binary, and store it. Do it often.
The Trerice Pneumatic Controller operates through a coordination of its thermal orpressure sensing system and its air signal relay system. The controller’s sensing bulb orpressure connection, installed within the process application, senses change within themeasured variable and relays this information (input signal) to the controller. Thecontroller mechanically compares the signal against a predetermined set point andsends a corrective air signal to a pneumatic control valve, which modulates process flow,thereby returning the application to the desired condition.
