Germany LORENZ sensor LORENZ model LORENZ price

LORENZ sensors, also known as displacement sensors, are a type of sensor used to detect the distance to an object to perform a preset function, and have been widely applied. Main products include mobile phone proximity sensors and long-distance measurement sensors, which are used in smart belts. Proximity sensors can be divided into optical proximity sensors, infrared proximity sensors, ultrasonic proximity sensors, and others based on their working principles. Most proximity sensors used in mobile phones are infrared proximity sensors, which feature an infrared emitting tube and an infrared receiving tube. When the infrared rays emitted by the transmitting tube are received by the receiving tube, it indicates that the distance is close, and the screen needs to be turned off to prevent accidental operation. When the receiving tube does not receive the infrared rays emitted by the transmitting tube, it indicates that the distance is far, and there is no need to turn off the screen. The working principles of other types of proximity sensors are similar; they also determine distance by emitting and receiving a certain substance, such as ultrasonic waves or light pulses.

LORENZ sensor features

Currently, baffles can be designed according to the water flow rate to reduce the water resistance generated when water flows through the flow sensor, thereby reducing head loss in the water system. However, baffles subjected to long-term water impact still face fatigue issues, and even if the flow value is calibrated at the factory, setpoint drift may occur. They are typically used where precise protection of flow values is not required, i.e., for break-flow protection against sudden interruption of water flow in pipes. There are very few designs in China specifically for water-source heat pump units. The baffle type is specifically developed for water flow monitoring in water-loop/ground-source heat pump air conditioning units. It is equipped with different baffles for different pipe diameters, and the water resistance of each baffle does not exceed 0.5 meters of water column, which is significantly lower than that of target-type sensors. Each baffle-type flow sensor is equipped with pipe fittings identical to those of the water-loop heat pump unit's water pipes. On-site installation only requires connecting to the water pipe without any modification to the baffle. Additionally, the pressure rating of the baffle-type flow switch is greater than 25bar, making it a low-cost flow switch for water-loop heat pump units with less stringent water flow requirements. Feedback from use in water-loop/ground-source heat pump units shows that differential pressure switches can effectively identify problems in the on-site installation of water-loop heat pump unit piping, completely avoiding heat exchanger freezing caused by low water flow. Flow sensors can also protect against heat exchanger freezing due to reduced water flow caused by clogged water filters. Furthermore, water pipe differential pressure switches do not carry the risk of fatigue failure associated with target flow switches. Especially when there is a small amount of air in the water pipes, the flow sensor operates very stably without the floating issues seen in target flow switches. Feedback from years of use has not revealed any faults with the differential pressure switch itself.

LORENZ sensor principle

Basic principles and types of ultrasonic flowmeters: When ultrasonic waves propagate in a flowing fluid, they carry information about the fluid's flow velocity. Therefore, the fluid's flow velocity can be detected by receiving the ultrasonic waves, which is then converted into flow rate. Based on the detection method, ultrasonic flowmeters can be classified into different types, such as transit-time difference method, Doppler method, beam deflection method, noise method, and correlation method. Ultrasonic flowmeters are non-contact instruments that have come into application in recent decades with the rapid development of integrated circuit technology. They are suitable for measuring fluids that are difficult to contact and observe, as well as large-diameter pipe flows. When linked with water level gauges, they can measure open-channel flow. Using ultrasonic flow measurement avoids installing measuring elements in the fluid, thus not changing the fluid's flow state or generating additional resistance. Instrument installation and maintenance do not affect production pipeline operation, making it an ideal energy-saving flowmeter. Industrial flow measurement commonly faces difficulties in measuring large pipe diameters and high flow rates. This is because general flowmeters incur manufacturing and transportation difficulties, increased costs, and higher energy losses as the measurement pipe diameter increases. Ultrasonic flowmeters avoid these disadvantages. Since various ultrasonic flowmeters can be installed externally for non-contact flow measurement, the instrument cost is basically independent of the measured pipe diameter. In contrast, the cost of other types of flowmeters increases significantly with diameter. Therefore, for larger diameters, ultrasonic flowmeters offer a better cost-performance ratio than other types with similar functions. They are considered superior instruments for large-diameter flow measurement. Doppler method ultrasonic flowmeters can measure two-phase media flow, making them suitable for measuring dirty flows such as sewage and wastewater. In power plants.

LORENZ sensor selection

When selecting flow sensors, users should choose suitable sensors based on their own needs. Many users have different requirements for the sensors they use, so the selected standards vary. If highly professional data and results are needed, national standards should be selected. However, if the sensor is only used as a simple instrument for rough analysis within an enterprise, enterprise standards can be selected. When purchasing flow sensors, careful consideration is essential, and one should choose sensors with guaranteed quality and good usability. Many people mistakenly believe that new sensors necessarily have higher technology, which is a one-sided view. New products must possess mature technology to be considered good products. In many economic sectors, accurate flow measurement has become very important. Nowadays, sensors are basically used to measure flow volume. Sensors sense fluid flow and convert it into usable output signals, making operations simpler and more convenient. The quantity of flowing objects passing through per unit time is called flow rate. Different flow sensors are used for different objects, often distinguished by the measured medium and measurement method. Flow sensors are generally used for the flow of media fluids in industrial pipelines, including gases, liquids, and steam. Several types of flow sensors can be universal for these various media. The first type is the vortex flow sensor. Another type is the ultrasonic flow sensor. With the development of ultrasonic technology, ultrasonic flow sensors can generally measure the flow of most flowing objects. Ultrasonic flow sensors have various measurement methods, each with its own characteristics. Selection should be based on factors such as the properties of the measured fluid, flow velocity distribution, pipeline installation location, and accuracy requirements. Since industrial flow measurement commonly faces difficulties in measuring large pipe diameters and high flow rates—because general flow sensors incur manufacturing and transportation difficulties, increased costs, and higher energy losses as the measurement pipe diameter increases—ultrasonic flowmeters avoid these disadvantages. The flow measurement accuracy of ultrasonic flow sensors is hardly affected by parameters such as temperature, pressure, viscosity, and density of the measured fluid. They can also be made into non-contact and portable measuring instruments, thus solving flow measurement problems for strongly corrosive, non-conductive, radioactive, and flammable/explosive media that are difficult to measure with other types of instruments.
