18、 signal used in industrial-process measurement and control systems to transmit information between the elements of such systems. It is applicable to: a) pneumatic controllers; b) pneumatic transmitters and information transmission systems. This standard does not apply to analogue pneumatic signals u
19、sed entirely within an element. The object of this standard is to establish: a) a standard operating pressure range for pneumatic information transmission systems; b) a standard air supply pressure (with limit values) for the operation of pneumatic controllers and transmitters, pneumatic information
20、 transmission systems, current-to-pressure transducers, and similar devices. 1.2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid.

25、a corresponding air pressure, interconnecting tubing and a receiving element responsive to air pressure which develops an output directly corresponding to the input information 2.3 current-to-pressure transducer a device which receives an analogue electrical signal and converts it to a corresponding

The unit for pressure in the International System of Units (SI) is the pascal (Pa), defined as one newton per square metre. Customary units for pressure a

The bar is not an SI unit but ISO1000 states that it may be used for fluid pressure. 1Pa=1N/m 2 =10 5 bar 100kPa=1bar 3.1 Range of the analogue pneumatic signal The range of the analogue pneumatic signal shall be as given in Table 1.

31、rent-to-pressure transducer may be connected directly (without using a positioner) to a pneumatic actuator for positioning a final control element with a nominal range of20kPa100kPa. Under operational conditions, if forces are exerted from the controlled medium to the final control element, a larger
32、 range is required for proper functioning. In this case, devices should be used with an output designed to vary from near zero to near supply pressure (preferably5kPa120kPa).
