Instrument knowledge|Classification of on-site detection instruments for industrial automation instruments

There are many types of industrial automation instruments. From the acquisition, transmission, reflection and processing of information, industrial automation instruments are divided into five categories: field measuring instruments, display instruments, control instruments, actuators, and centralized detection and control devices. Each major category can be subdivided into several subcategories. Let's take a look at the classification of on-site inspection instruments.
Classification of field measuring instruments:

1. Material level and liquid level meter:
Continuous level measuring instruments: buoyancy level gauge, capacitive level gauge, radar level gauge (DCRD1000A series radar level gauge), laser level gauge, ray level gauge, ultrasonic level gauge, direct reading Type liquid level gauge, external micro-vibration level gauge, differential pressure level gauge, heavy hammer level gauge.
Limit level measuring instruments: Capacitor/pole type level switch, float type level switch, tuning fork type level switch, rotary vane level switch, ultrasonic level switch

    Instrument knowledge| Installation and use of Insertion intelligent electromagnetic flow meterThere are many types of electromagnetic flow meters, which can be divided into pipeline electromagnetic flow meters and plug-in electromagnetic flow meters according to different installation methods. The plug-in electromagnetic flow meter retains the advantages of the previous pipeline electromagnetic flow meter, but also overcomes the shortcomings of the pipeline electromagnetic flow meter on large-diameter pipelines, such as difficulty in installation, high cost, and difficulty in periodic calibration. It is widely used in tap water, steel and iron. , Petroleum, chemical industry, industry, water conservancy and other sectors of conductive fluids, as well as acid, alkali, salt and other corrosi...
