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

    Common problems of radar level transmitter Radar level transmitter are mainly installed in various metal and non-metal containers or pipelines to perform non-contact continuous measurement of the level of liquids, slurries and particles. It is also suitable for occasions with dust, inert gas and steam. The radar level transmitter has the characteristics of safety, cleanliness, high precision, long life, stable and reliable, convenient installation and maintenance, and simple reading. Because there are no moving parts, maintenance is minimal, but some minor faults will inevitably occur during use. Here is a breakdown analysis and countermeasures for everyone.1. If an alarm occurs when the liquid level is within the applicable range, then:a. When the liquid leve...

    Radar level meter is a common product type of level meter, which has the advantages of accurate measurement, stable performance, high reliability, easy maintenance, and wide application range. It can be installed in various metal and non-metal containers or tanks to measure the level of liquid, slurry and granular materials. So, under what special conditions will it be installed?1. Selection under the condition of stirringIn a tank with stirring, guided wave radar level gauges are generally not used. The strength of stirring can easily bring the cable of the guided wave radar into the stirring device, or bend the rod of the guided wave radar. So you can only choose non-contact measurement of FM or high-frequency horn-mouth radar level meter to measure.2. Selection under vacuum conditionsUn...

    Radar level meter measures ammonia in a fertilizer plant Ammonia refers to an aqueous solution of ammonia with a strong pungent odor and weak alkaline. Store in a cool, dry, ventilated place, away from fire and heat. Avoid direct sunlight and keep the container tightly closed. It should be stored separately from acids, metal powders, etc. Open-air storage tanks must have cooling measures in summer. Ammonia is often used in agricultural fertilizers, in the chemical industry for the manufacture of various ammonium salts, aminating agents for organic synthesis, and catalysts for the production of thermosetting phenolic resins. In the textile industry, it is used in wool spinning, silk, printing and dyeing industries, for washing wool, woolen cloth, grey cloth, oil stains, dyein...
