Here’s an example: Business cards are small but contain important information. They’re often saved or even passed around between contacts, business partners, and potential customers. As such, they need to be thicker, stiffer, and more durable than your average piece of paper. On the other hand, flyers announcing a sale or an event have a temporary use. They communicate information to whoever receives them, and then they’re usually thrown away. As such, these are often printed on flimsier paper with a lighter GSM. 100% Recyclable and Degradable We pick the paper material directly from the natural Eucalyptus spp, no auxiliary ingredients.

Humidity interference, when the humidity increases, it will cause the insulator resistance to decrease, the dielectric constant to increase, the skeleton to be fluffy, and the resistance to increase, resulting in an increase in leakage current and changes in capacitance and inductance. Also, it softens the colloid and reduces measurement accuracy. Chemical interference, chemical interference usually refers to some corrosive gases, such as acids and alkalis. The long-term action of these gases will not only damage the instrument and internal components, but also conduct electricity with the metal, affecting the normal operation of the radar level transmitter.

Product features: Large display range, wide range of use, suitable for low temperature, medium temperature, high pressure occasions. It can be matched with remote transmitter output 4-20MADC standard signal to realize remote display of liquid level guage. It can also be matched with liquid level switch to realize liquid level control. Generally speaking, the material level feedback is inaccurate and untimely, which is very prone to explosion events, and there is a greater safety risk. Therefore, the requirements for the radar level meter are very high, but the radar level meter often has abnormal material level jumps or falls, or even crashes, resulting in large errors in material level measurement, which brings trouble to production and sales.

Power supply and output signal, the power supply has 220 V A C, 24 VDC, and the two-wire or four-wire system can be selected according to the needs. Output signal 4 ~ 20 mA DC or digital signal, select the appropriate model according to the needs. The above are all factors that need to be considered when selecting a radar level transmitter. The essence of the details is a serious attitude and a scientific spirit. I hope that every user can choose a suitable radar level meter.

The electromagnetic wave emitted during measurement can pass through the vacuum, no transmission medium is required, and the anti-interference ability is strong, and it is not affected by temperature, wind, water vapor, water mist, rain, etc. It can be used for liquid level measurement of almost all liquids, and can be continuously measured on-line unattended. Large measurement range, high precision, mature technology and stable performance.

Any appreciable gain in boiler feedwater achieved through the process reduces the amount of energy (fuel) required at the boiler— in fact, every 10.8°F (6°C) rise in boiler feedwater amounts to a one percent savings in fuel cost. Inadequate level controls can inhibit the deaeration process (level too high) or reduce/shutdown feedwater flow to the boiler (level too low). The former affects hardware longevity and efficiency, while the latter risks production losses and possible damage to pumps. Discover more info on https://www.kaidi86.com/.

In the process of cement production, material level detection and material level alarm control play an important role from mining and crushing to storage and packing of finished cement. But because of the complex working conditions of cement plant, radar level meter has no small difficulty in measuring. Today, I would like to talk with you about specific difficulties and solutions. First cement plant material for measurement in the dust under the condition of particularly large, especially some pneumatic feed bin, involves the kinds of materials, material particle size is differ, dielectric constant is different also, such as broken limestone, raw meal, clinker, fly ash, coal, cement, the level of the bunker, it is very difficult to accurately measure Especially fly ash bin with low dielectric constant.

Under many operating conditions, ultrasonic level meter and radar level meter are commonly used. Some users are very entangled in the choice of these two level meter and do not know how to choose. Today, let’s talk about the principles and selection principles of these two types of level meter . Principle and selection principle of ultrasonic level meter. Working principle: The ultrasonic pulse probe emits a beam of ultrasonic pulses to the measured medium, and the sound wave is reflected by the liquid surface. The distance between the liquid levels is measured by measuring the time difference between the emission and reflection of the sound waves. Since the ultrasonic level gauge is not a liquid, it can be used to measure corrosive, non-volatile and non-foaming places.

The third case is that, during the commissioning stage of a platform construction, when the liquid level is higher than 3800mm, the radar level meter of the dirty oil tank will frequently jump to 0mm, which leads to the shutdown of the fourth-stage production unit. After on-site inspection, the power supply voltage of the radar level meter transmitter is only 9.5V, which is lower than the working power supply voltage of the radar level meter. By further searching for the cause of the failure, found that when the high liquid level, the voltage at the power supply is 23.7V, the safety gate output drops to 9.7V, judged as a safety gate transmitter failure. After replacing the safety grid, the voltage returns to normal, the cabin radar level meter in the test to rule out the problem.
