Proxitron流量傳感器的功能和應用領域
Proxitron的流量傳感器可以監(jiān)測液體或氣體形式的介質(zhì)的流速，以便簡單有效地控制流程。這種傳感器系統(tǒng)的基礎是量熱原理。
它利用在流過它的介質(zhì)表面上的冷卻效果，類似于在風中握住手指感覺冷時。在流量傳感器上，傳感器的表面被加熱到規(guī)定的溫度。如果該表面暴露于流動，傳感器表面冷卻下來。流動越強，冷卻效果越強，其用作流速的測量。以電子方式分析流的冷卻效果，并且流量傳感器根據(jù)可用于監(jiān)測流量的版本，輸出基于此的輸出信號。
流量傳感器的可能用途非常多樣，從一般空調(diào)技術(shù)到萃取系統(tǒng)，一直到監(jiān)測冷卻劑和潤滑劑回路。與監(jiān)測風扇或泵的旋轉(zhuǎn)運動的間接流監(jiān)測相反，利用該原理，介質(zhì)的流動被直接監(jiān)測，因此還能夠檢測污染的過濾器以及流動回路中的堵塞或堵塞。可調(diào)節(jié)的流量值可以提供流量下降到zui小可接受限度以下的提前警告，例如，以迅速地啟動排氣系統(tǒng)上的維護工作。 Proxitron流量傳感器的零維護和磨損操作意味著它們優(yōu)于其他傳感器系統(tǒng)，如空氣方向繼電器和葉片式風速計，并且在需要可靠*流量監(jiān)測的情況下成為。
無縫封閉外殼中的傳感器設計使其非常適合在高污染環(huán)境中使用。 Proxitron空氣流量傳感器（空氣流量監(jiān)測器）及其全塑料外殼，在任何存在腐蝕性化學氣體環(huán)境的家中。它們甚至耐受來自電鍍浴的硫酸負載煙霧，并且可以無缺陷地操作許多年。
Proxitron的流量傳感器有多種型號。在用于監(jiān)測氣體形式和液體形式的介質(zhì)的傳感器之間進行區(qū)分。
用于氣體的流量傳感器（也稱為空氣流量監(jiān)測器）大多具有緊湊的塑料外殼，允許它們?nèi)菀椎匕惭b在現(xiàn)有的排氣系統(tǒng)或通風系統(tǒng)中。
液體流量傳感器具有常見管螺紋尺寸的不銹鋼過程連接。在這兩種情況下，變量都可用于交流或直流工作電壓，具有不同的開關輸出類型或具有模擬輸出。該設備可以提供各種長度的固定連接電纜或常用的M12插頭連接器。 Proxitron流量傳感器的突出之處還在于它們易于操作。在按下按鈕時，傳感器檢測流量并調(diào)整流量極限值，以可靠地檢測流量的故障。這提供了在工業(yè)領域以及空調(diào)技術(shù)和樓宇自動化的各種可能的用途。該范圍由協(xié)調(diào)配件完成，其中包括傳感器的耐壓安裝。無論何時需要高性能但具有成本效益的解決方案來進行流量監(jiān)控，我們非常樂意為您提供專業(yè)知識。
Proxitron流量傳感器的功能和應用領域
The design of the sensors in a seamless enclosed housing makes them perfect for use in high-pollutionenvironments. Proxitron air flow sensors (air flow monitors), with their all-plastic housing, are at home wherever there are aggressive chemical atmospheres. They are even resistant to sulphuric-acid-laden fumes from galvanic baths, and can operate flawlessly for many years.
Flow sensors from Proxitron are available in various versions. A distinction is made between sensors formonitoring media in gas form and in liquid form.
Flow sensors for gases (also known as air flow monitors) mostly have a compact plastic housing, allowing them to be easily installed in existing exhaust systems or ventilation systems.
Flow sensor for liquids have stainless steel process connections in common pipe thread sizes. In both cases, variants are available for AC or DC operating voltage, with different switching output types or with analogue output. The devices can be supplied both with fixed connection cables of various lengths or with the customary M12 plug connector. Proxitron flow sensors are also distinguished by their ease of operation. At the push of a button, the sensor detects the flow und adjusts the flow limit value to reliably detect a breakdown of the flow. This offers a variety of possible uses in a large range of sectors of industry, as well as for air-conditioning technology and building automation. The range is completed by coordinated accessories, allowing among other things pressure-resistant installation of the sensors. Wherever a high-performance but cost-effective solution is required for flow monitoring, we are happy to place our expertise
