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|Radar level meter, how to reduce the interference in the tank on the measurement When we install the radar level meter, we will encounter many on-site storage tanks with supports, such as beams and brackets,etc . . . These supports will interfere with the signal of the radar level meter. If the above interference objects appear in the radar emission area, when the normal liquid level is below the interference objects, it will inevitably affect the normal measurement of the radar level meter, and false echo signals will appear. When encountering such situations, there are the following solutions: Method 1: Cleaning up on-site interferenceIf the interference is too large, completely occludes or most of the transmission signal of the radar level meter,...

    When selecting the type of radar level gauge, consider the influence of stirring and vacuuming, and pay attention to the power supply and output signal.1. Selection under stirringIn a tank with stirring, guided wave radar is generally not used. The force of stirring can easily bring the cable of the guided wave radar into the propeller, or bend the rod of the guided wave radar. Therefore, only high-frequency or low-frequency horn radar for non-contact measurement can be selected.If the lowest liquid level on site is above the stirring propeller, it generally has no effect on the measurement. If the minimum liquid level will be lower than the stirring propeller, it is necessary to filter out the signal reflected by the propeller by learning the function of false echo, so as to ensure that t...

    Intelligent radar water level meter helps carry out flood prevention workRecently, as tropical disturbances in the southern coastal areas of my country have developed into tropical depressions, heavy rainfall has appeared in many areas of southern my country, and the flood control warning has been sounded. Since my country entered the flood season, a new round of flood control and early warning work has once again been put on the agenda. In flood warning work, the status of monitoring instruments can hardly be shaken. In order to do a good job in flood control and early warning, and prevent problems as much as possible, the intelligent radar water level meter DCRD1000A2 researched and developed by Xi'an Dechuang Electrictrical Technology Co., Ltd. not only greatly improves the measurem...

    Why choose the radar level sensor in industrial process level instruments? The radar level sensor can measure the level that many other level instruments cannot measure, radar level sensor uses the microwave pulse measurement method and can work normally within the specified frequency range. It can be used in environments where inert gases and volatilization exist under the interference of temperature or pressure changes. The radar level sensor is a non-contact continuous measurement type process level instruments, which can be used to measure the level of liquids or solids, particle sizes and particulate materials. It corresponds to 4-20mA output, which is set by inputting the empty tank height E (=zero point), the full tank height F (=full scale) a...
