摘要: A pneumatic controller providing an outgoing signal proportional to the magnitude and time integral of the incoming signal comprises a first sealed-beam balance with a rigid beam attached onto a diaphragm defining four chambers, a second sealed-beam balance with two chambers performing the flow relay function, and a pressure balance with two chambers for copying the integral pressure. In the case of a pneumatic controller providing an outgoing signal proportional to the magnitude, time integral and time derivative of the incoming signal, the first sealed-beam balance is preceded by a time derivative stage comprised of a sealed-beam balance with four chambers similar in construction to the first sealed-beam balance.
