How to repair the failure of ultrasonic flowmeter sensor? Posted by : admin / Posted on : Oct 25， 2021

The ultrasonic flowmeter sensor that people say is composed of two parts: conversion element and sensitive element. The conversion element refers to the part of the sensor that converts the measurement of the sensitive element lamenting infection or response into an electrical signal suitable for transmission or measurement; the sensitive element refers to the part of the sensor that can directly lament the infection or response being measured.

Because the output of the sensor is generally a very weak signal, it needs to be modulated and amplified. But with the rapid development of science and technology, people also install this part of the circuit and the power supply and other circuits inside the sensor. In this way, the sensor can output usable signals that are convenient for processing and transmission.

In the case of relatively backward technology in the past, the so-called sensor refers to the sensitive element, and the transmitter is the conversion element. Sensors are generally composed of sensitive elements and conversion elements. They are a general term for equipment or devices that can detect the delineated measured and convert them into usable output signals according to certain rules. When the output of the sensor is a defined standard signal, it is a transmitter.

The equipment that converts physical signals into electrical signals is called a sensor, and the equipment that converts non-standard electrical signals into standard electrical signals is called a transmitter.

The primary appearance refers to the on-site measurement appearance or base control meter, and the secondary appearance refers to the use of the primary meter signal to complete other functions. The transmitter and sensor together constitute a monitoring signal source for automatic control.

The combination of different sensors and corresponding transmitters can meet the needs of different physical quantities. The weak electrical signal collected by the sensor is amplified by the transmitter, and the signal is amplified to facilitate transmission or launch of the control element.

The sensor converts non-electrical physical quantities into electrical signals and transmits these signals directly to the transmitter.
There is also a transmitter that sends the water in the lower part of the liquid level sensor and the condensed water of the upper steam through the outer surface pipe to both sides of the corrugated pipe of the transmitter, and the expansion device uses the pointer to indicate the water level with the differential pressure belt on both sides of the corrugated pipe. A kind of distant appearance. In addition, there is also a transmitter that converts electrical analog quantities into digital quantities.
