壓力開關(guān)是一個(gè)組件，它將輸入時(shí)的當(dāng)前壓力或壓力差與預(yù)設(shè)水平進(jìn)行比較，如果輸入壓力低于或高于此水平，則輸出返回信息。與機(jī)械開關(guān)相比，這種電子開關(guān)具有更高的精度和可靠性以及更好的長(zhǎng)期穩(wěn)定性。通過(guò)電源執(zhí)行器正確連接，此開關(guān)可作為布爾反饋調(diào)節(jié)器運(yùn)行。
該儀器設(shè)計(jì)用于廣泛應(yīng)用于一系列非常小的壓力下的測(cè)量和調(diào)節(jié)，特別是在空調(diào)，通風(fēng)，燃燒過(guò)程控制，設(shè)備設(shè)計(jì)等方面。許多應(yīng)用都提供醫(yī)療技術(shù)和實(shí)驗(yàn)室測(cè)量。該傳感器設(shè)計(jì)用于測(cè)量壓差，這一事實(shí)還包括測(cè)量相對(duì)壓力的要求。然而，沒有確定高的共同壓力測(cè)量值，例如壓力分布系統(tǒng)中的孔板量規(guī)的測(cè)量值?？梢灾圃靿毫Ψ秶哂?00kPa的開關(guān)，但僅作為量具。被測(cè)介質(zhì)可以是非腐蝕性氣體。在制造商應(yīng)咨詢使用在高于2.5 kPa的壓力下允許的非腐蝕性液體。
整個(gè)換能器，即壓力傳感器，電源，補(bǔ)償和放大電路以及用于提高抗噪性的濾波器放置在聚碳酸酯的小塑料盒中，該塑料盒可以安裝在面板或DIN條帶上。壓力供應(yīng)由直徑5毫米的鍍鎳黃銅進(jìn)口實(shí)現(xiàn)，適用于小軟管，可能是較高壓力的快速接頭。此外，介質(zhì)與硅，硅橡膠和塑料物質(zhì)聚醚酰亞胺接觸。

這種類型的儀器通過(guò)壓電原理上的硅膜來(lái)測(cè)量壓力。因此，該換能器具有良好的過(guò)載耐久性，抗振動(dòng)并且可以在任意位置工作。對(duì)于一些應(yīng)用來(lái)說(shuō)，利用一個(gè)換能器測(cè)量正壓和負(fù)壓是有利的。電子電路通過(guò)表面安裝技術(shù)實(shí)現(xiàn)。
輸出實(shí)現(xiàn)為具有開路集電極的NPN晶體管。這種類型的輸出允許簡(jiǎn)單地實(shí)現(xiàn)邏輯電平，用于直接輸入到穩(wěn)壓器或連接繼電器以用于功率驅(qū)動(dòng)器。在殼體的右側(cè)是LED，其指示晶體管開關(guān)接通狀態(tài)。隱含地將開關(guān)設(shè)置為晶體管開關(guān) - 隨著壓力增加超過(guò)預(yù)設(shè)水平。輸出信號(hào)可以通過(guò)分流跳線來(lái)抵消。固定滯后cca 1.5％來(lái)自標(biāo)稱范圍是內(nèi)置的，以防止在通過(guò)切換級(jí)別時(shí)發(fā)生振蕩。通過(guò)多匝微調(diào)電位器實(shí)現(xiàn)開關(guān)電平調(diào)節(jié)，可通過(guò)右側(cè)的孔，LED旁邊進(jìn)行調(diào)節(jié)。為了保持高IP保護(hù)，這個(gè)孔被M3螺釘覆蓋，這必須在調(diào)整拆卸期間。開關(guān)電平調(diào)整可以直接在制造商處訂購(gòu)，可以通過(guò)實(shí)驗(yàn)或外部壓力表分別通過(guò)帶有測(cè)量?jī)?nèi)部電壓的外部直流電壓表進(jìn)行調(diào)整，并根據(jù)公式重新計(jì)算，該公式位于本文件的背面。配有LCD的壓力開關(guān)可通過(guò)按下內(nèi)部按鈕顯示調(diào)節(jié)的水平。
開關(guān)可以由12-36V范圍內(nèi)的DC電壓供電。在此范圍內(nèi)的電源電壓的變化對(duì)測(cè)量精度沒有任何實(shí)際影響。在蓋子下面，放置了短路跳線，用于選擇阻尼時(shí)間常數(shù)。
Pressure switch is a component, which compares current pressure or pressure difference on input with preset level and output returns information if input pressure is below or above this level. In comparison with mechanical switches this electronic one has higher accuracy and reliability and better long term stability. With power actuator proper connection may this switch operate as a boolean feedback regulator.
This instrument is designed for a wide application in a branch of measurement and regulation in a range of very small pressures, especially in air-conditioning, ventilation, combustion process control, appliance design, etc. Many applications are offered in a medical technology and in the laboratory measurements. This transducer is designed for measurement of the differential pressure and this fact also includes a requirement for measurement of the relative pressures. However, it is not determined for a high common pressure measurement, such as measurement on the orifice gauges in the pressure distribution systems. It is possible to manufacture switches with pressure range higher then 100kPa, but only as a gage. The medium being measured may be a non-aggressive gas. Use of the non-aggressive liquid, which is permitted in the pressures higher than 2.5 kPa, should be consulted with manufacturer.
The whole transducer, i.e. a pressure sensor, supply, compensation and amplifying circuits as well as a filter for increase of the noise immunity are placed in a small plastic box from polycarbonate, which may be installed on a panel or DIN strip. The pressure supplies are realized by the nickel-plated brass inlets with a diameter 5 mm, which are suitable for use of a small hose, possibly a quick coupling for higher pressures. In addition, the medium comes into contact with silicon, silicone rubber and a plastic substance polyetherimide.
Electric connection into the measuring circuit is realized by a sealing arrested miniature connector type DIN 43650 - C with a cable outlet PG7, which enables to use a cable with a diameter max. 6.5 mm.
This type of instrument measures the pressure by means of a silicon diaphragm on a piezoelectric principle. Therefore this transducer attains good overload endurance, is resistant against vibrations and may work in an arbitrary position. It is an advantage for some applications to measure both the positive and negative pressure with one transducer. Electronic circuitry is realized by a surface mount technology.
Output is realized as NPN transistor with open collector. This type of output allows simply realize logic levels for direct input to regulator or connect relay for power actuator driving. On the right side of the case is LED, which indicates transistor switch-ON state. Implicitly the switch is set to transistor switch-ON with increasing pressure over preset level. Output signal can be negated by shunting jumper. Fixed hysteresis cca 1,5% from nominal range is built-in to prevent oscillations during pass over switching level. Switching level adjustment is realized by multi-turn trim-pot, which is accessible through the hole in right side, beside LED. To keep high IP protection this hole is covered by M3 screw, which must be during adjustment dismount. Switching level adjustment can be ordered directly at the manufacturer, can be adjusted experimentally or with external pressure meter, respectively by external DC voltmeter with measuring internal voltage and recalculating according formula, which is placed on the rear side of this document. Pressure switch fitted with LCD allow displaying adjusted level by press the internal button.
The switches may be supplied by a DC voltage in a range 12–36 V. Change of the supply voltage within this range has not any practical impact on the measurement accuracy. Under the cover, there are placed short-circuiting jumpers for selection of the damping time constant.
