FOXBORO繼電單元C0135YW描述
繼電器是氣動(dòng)放大器。與其電子對(duì)應(yīng)物一樣，繼電器的功能是將輸入信號(hào)（氣壓信號(hào)）的微小變化轉(zhuǎn)換為輸出信號(hào)的大變化。通常，輸入中的7kPa或1psi變化將在輸出中產(chǎn)生大約80kPa或12psi的變化。
空氣供應(yīng)通過(guò)安裝繼電器的儀器表面上的端口進(jìn)入繼電器。 輸入信號(hào)（噴嘴壓力）通過(guò)另一個(gè)端口進(jìn)入繼電器并作用在隔膜上。由于隔膜與閥桿接觸，兩者一致地移動(dòng)。
當(dāng)輸入信號(hào)增加時(shí)，閥桿推動(dòng)球閥，球閥又移動(dòng)扁平彈簧，允許供應(yīng)空氣進(jìn)入繼電器主體。閥桿的進(jìn)一步運(yùn)動(dòng)使其關(guān)閉排氣口。因此，當(dāng)輸入壓力增加時(shí)，閥桿（排氣）閥關(guān)閉，供應(yīng)閥打開(kāi); 當(dāng)輸入減少時(shí)，閥桿打開(kāi)，供應(yīng)閥關(guān)閉。這改變了輸出的壓力。
A relay is a pneumatic ampliflier.Like its electronic counterpart,the function of the relay is to convert a small change in the input signal (an air pressure signal) to a large change in the output signal. Typically a 7kPa or 1psi change in the input will produce approximately an 80kPa or 12psi change in the output.
The air supply enters the relay through a port on the surface of the instrument on which the relay is mounted. The input signal (nozzle pressure) enters the relay through another port and actsm on the diaphragm. Since the diaphragm is in contact with a stem valve, the two move in unison.
As the input signal increases,the stem pushes against a ball valve which in turn moves a flat spring, allowing the supply air to enter the relay body. Further motion of the stem valve causes it to close off the exhaust port.Thus,when the input pressure increases,the stem (exhaust)valve closes and the supply valve opens;when the input decreases, the stem valve opens and the supply valve closes. This varies the pressure to the output
