A sensor is defined as a device or device that senses a specified measurement and converts it into a usable signal according to a certain pattern. The sensor is composed of two parts, namely the sensing element and the conversion element. The sensitive element refers to the part of the sensor that can directly sense or respond to the measurement; The conversion element refers to the part of the sensor that converts the measured perception or response of the sensitive element into an electrical signal suitable for transmission or measurement. In sensors, transmission refers to transmission, and sensing refers to perception. In fact, there is perception first, then transformation, and finally transmission. Perception is the foundation, transformation is the means, and transmission is the goal. When a signal converter and sensor are integrated, it is called a transmitter. According to the definition of the Encyclopedia of China, a transmitter is a sensor that outputs a standard signal. A transmitter of a national standard is defined as a device that enables the output to be a specified standard signal, which is called a transmitter. Transmitter literally, change refers to transformation, and send refers to output. Transform is the foundation, output is the goal. The concept of a transmitter is an instrument that converts a non-standard electrical signal into a standard electrical signal, and a sensor is a device that converts a physical signal into an electrical signal. The sensor converts non-electrical physical quantities such as temperature, pressure, liquid level, material, gas characteristics, etc. into electrical signals or sends physical quantities such as pressure and liquid level directly to the transmitter. The transmitter amplifies the weak electrical signal collected by the sensor in order to transmit or activate the control element. Or convert the non-electric input of the sensor into an electrical signal and amplify it for remote measurement and control. Analog quantities can also be converted to digital quantities as required. Sensors and transmitters are both thermal instrument concepts. Together, the sensor and transmitter form the monitoring signal source for automatic control. Different physical quantities require different sensors and corresponding transmitters.
