876PH-TYAA-7M變送器是一種傳感器的一種，它將傳感器測量到的物理量轉(zhuǎn)換成標準電信號，以便于后續(xù)的數(shù)據(jù)處理、顯示、控制等操作。通常，變送器輸出的信號是模擬信號，如電流信號或電壓信號，其大小和形式符合國際標準，可以直接與控制系統(tǒng)或顯示設(shè)備進行連接。
變送器通常由傳感器、信號轉(zhuǎn)換器、放大器和輸出電路等組成。傳感器負責(zé)測量物理量，如溫度、壓力、液位、流量等，并將其轉(zhuǎn)換成電信號。信號轉(zhuǎn)換器則將傳感器輸出的微弱電信號轉(zhuǎn)換成標準電信號，以便于后續(xù)處理。放大器則用于放大信號，提高信號的幅值，以便于后續(xù)電路的處理。最后，輸出電路將標準電信號輸出到控制系統(tǒng)或顯示設(shè)備中。
變送器具有測量準確、穩(wěn)定性好、可靠性高等優(yōu)點，并且能夠適應(yīng)不同的工作環(huán)境和應(yīng)用場景。因此，在各種工業(yè)自動化和控制系統(tǒng)中，變送器都扮演著重要的角色。常見的變送器類型包括溫度變送器、壓力變送器、液位變送器、流量變送器等。

876PH-TYAA-7M transmitter is a kind of sensor, it converts the physical quantity measured by the sensor into a standard electrical signal, in order to facilitate subsequent data processing, display, control and other operations. Usually, the signal output by the transmitter is an analog signal, such as a current signal or a voltage signal, its size and form meet international standards, and can be directly connected to the control system or display device.
The transmitter is usually composed of a sensor, a signal converter, an amplifier and an output circuit. Sensors are responsible for measuring physical quantities, such as temperature, pressure, level, flow, etc., and converting them into electrical signals. The signal converter converts the weak electrical signal output by the sensor into a standard electrical signal for subsequent processing. The amplifier is used to amplify the signal and increase the amplitude of the signal in order to facilitate subsequent circuit processing. Finally, the output circuit outputs the standard electrical signal to the control system or display device.
The transmitter has the advantages of accurate measurement, good stability and high reliability, and can adapt to different working environments and application scenarios. Therefore, in various industrial automation and control systems, transmitters play an important role. Common transmitter types include temperature transmitters, pressure transmitters, level transmitters, flow transmitters, etc.
