簡介
1.機械壓力開關(guān)的應(yīng)用
機械壓力開關(guān)也稱之為水電壓力監(jiān)視器，用來連結(jié)或者斷開電路。一個壓力開關(guān)可以作為一個單元組合元件和一臺視覺或者聲音的監(jiān)視器或者指示器。 巴克斯代爾壓力開關(guān)主要應(yīng)用于在液壓系統(tǒng)里：
1）監(jiān)視器的最小壓力例如對泵體進行保護避免再干燥的條件下運行，或者對油潤滑系統(tǒng)的進行保護。
2) 監(jiān)視器的最高壓力,例如自動斷開功能或者在減壓閥閥口達到限制壓力之前發(fā)出報警 ( 圖1).
巴克斯代爾壓力開關(guān)的另外一個用途是對貯存裝載過程進行控制。在達到貯存量的限值后(Pmax)，流體被停止，泵件關(guān)閉。 如果貯存壓力達成最小值(Pmin)，流體/泵體將再次自動啟動。 開關(guān)的滯后效應(yīng)(Pmax-Pmin)可以通過兩個壓力開關(guān)和一個螺線管閥門自由進行選擇(圖2).
在一定壓力范圍內(nèi)，存儲過程可以通過一個單壓力開關(guān)裝載進行控制，即KD1(小型壓力開關(guān))巴克斯代爾對該應(yīng)用作了專門的設(shè)計 (參閱第54頁)。 Pmax和Pmin壓力點的設(shè)定由廠家根據(jù)您的要求進行設(shè)定。
2.壓力開關(guān)的機械壽命和準確度
壓力開關(guān)的機械壽命和準確度取決于頻率和壓力峰值轉(zhuǎn)換，負荷循環(huán)的次數(shù)以及溫度的影響。最高準確超過30%，最長的機械壽命低于性能范圍規(guī)定的70% (圖3).
3.觸點材料
巴克斯代爾壓力開關(guān)裝備由微型開關(guān)銀質(zhì)接觸材料。根據(jù)相關(guān)要求，我們也供應(yīng)鍍金微型開關(guān)接觸材料。鍍金的接觸材料大部分使用在暴露于低電負荷的微型開關(guān)上。圖4描述了銀質(zhì)或鍍金接觸材料的標準值。我們很高興能夠提供適合您需要的材料。
摘要
電流和電壓不應(yīng)該超過0.12VA。建議數(shù)值：電流范圍應(yīng)該在<400 mA 和電壓在<30 V。如果作用于交流電，上述數(shù)值為峰值。

簡介
4，接觸保護
所使用的微動開關(guān)(MS)通常適于雙向和交流運作。電感性負載，電容負載和電燈負載可以在相當大程度上降低微動開關(guān)的預期壽命，不過在極端情形下，會使接觸材料損壞。
電容負載和電燈負載
電容負載和電燈負載可能伴隨著非常高的放電率或者起動電流15 倍的電流。 在這種情況下，必須準備相應(yīng)限流器(例如使用保護電阻) (見圖5和圖6)。
電感性負載
高感應(yīng)峰值負載在斷開時，在相當大程度上地降低微動開關(guān)的壽命。必須按照圖7和圖8的要求配置保護導線。個別的元件的類別根據(jù)相關(guān)的應(yīng)用而定( 二極管,變阻器等)。
5.關(guān)于系統(tǒng)內(nèi)的脈動和振動怎樣進行補救：
關(guān)于系統(tǒng)內(nèi)的脈動和振動能對壓力開關(guān)的功能造成影響。有兩不同類壓力開關(guān)，類型一：對在實際操作內(nèi)發(fā)生脈動和振動進行保護。類型二：精密設(shè)計或最佳的調(diào)整能夠使其在這樣的影響下更加敏感。關(guān)于振動阻力參考第4 頁和第5的小型壓力開關(guān)數(shù)值。
為保證的壓力開關(guān)的功能，請遵循下列建議：
1.機械振動
使用橡膠減震墊，當把裝置安裝在墻上時。
2.媒介的脈動/ 振動
- 使用靈活的軟管。 如果不具備該技術(shù)，在壓力開關(guān)的前面安置衰減器，例如：
- 螺旋管
- 商業(yè)脈動衰減器
- 隔膜式蓄能器
當氣穴加強振動時，請保證液壓系統(tǒng)能夠正確排放。

1. Applications for Mechanical Pressure Switches
Pmax + xbar
24V
Mechanical pressure switches, also known as hydro-electric pres¬sure monitors, are used to connect or disconnect electric circuits. A pressure switch can serve as a modular unit as well as an opti¬cal or acoustic monitor or indicator. Barksdale pressure switches are chiefly used in hydraulic systems for:
a) monitoring minimum pressures such as protecting pumps from
dry operation or as protection for oil lubrication systems.
b) monitoring maximum pressures such as automatic switch-off
function or warning before a relief-valve jet reaches its limit pres¬
sure (Fig. 1).
Another application for Barksdale pressure switches is the control of storage loading processes. After the storage capacity is reached (Pmax) the flow is stopped and the pump shuts down. If the storage pressure reaches a certain minimum (Pmin) the flow/ pump automatically starts up again. The switch hysteresis (Pmax -Pmin) can be freely selected via two pressure switches and one solenoid valve (Fig. 2).
Within certain pressure ranges the storage process can be con¬trolled with a single pressure switch, the KD1 (compact pressure switch) which Barksdale specifically designed for this application (see page 54). The pressure set points Pmax and Pmin are fac¬tory set, according to your requirements.
2. Mechanical Life Span and Accuracy of Pressure Switches
The life span and accuracy of mechanical pressure switches de¬pends on the frequency and peaks of pressure changes, number of load cycles, and influence of temperature. The highest accuracy is achieved above 30%, the longest life span below 70% of the performance range (Fig. 3).
Adjustable Range
30% 70% 100%
Accuracy satisfactory good excellent
Life Span excellent good satisfactory
3. Material of Contacts
Barksdale pressure switches have silver contact microswitches. On request, we also supply microswitches with gold-plated contacts. Gold-plated contacts are almost exclusively used on microswitches that are only exposed to low electrical loads. Fig. 4 depicts the standard values of silver or gold-plated contacts. We would gladly assist you in the selection of the material best suited for your application.
Summary
Current and voltage should not exceed 0.12 VA. Recommended values: the current should range at < 400 mA and the voltage at < 30 V. If operated on alternating current the above values are peak values.

4, Contact Protection
The microswitches (MS) used are normally suitable for both direction and alternating current operation. Inductive, capacitive and lamp loads may, however, considerably reduce the life expectancy of a microswitch and, under extreme circumstances, even damage the contacts.
Capacitive Loads and Lamp Loads
Capacitative and lamp loads may be accompanied by very high discharge rates or starting current rushes 15 times higher than the rated value. Under such circumstances, it is necessary to provide for corresponding current limiters (for instance the use of a protective resistance) (see fig. 5 and 6).
Inductive Loads
High inductive peak loads at the moment of disconnection may considerably reduce the life span of a microswitch. The necessary protective wirings may be accomplished according to fig. 7 and 8, the ratings of the individual elements (diode, varistor etc.) being determined by the corresponding application.
5. Pulsation and Vibrations within the system? How to remedy the problem:
Pulsation and vibrations within the system can affect the function of the pressure switch. There are two different types of pressure switches, type A is sufficiently protected against pulsation and vibrations occurring in practical operation due to its solid design. Type B is designed for precision or finest adjustments which, consequently, makes it more sensitive toward such influences. Please refer to page 4 and 5 for compact pressure switch values regarding vibration resistance.
To ensure the proper functioning of the pressure switch, please observe the following recommendations:
1. Mechanical Vibrations
Use rubber buffers when mounting the units to the wall.
2. Pulsation/Vibration of the Medium
Use flexible hose pipes. If this is technically not possible, place attenuators in front of the pressure switch, for example:
- helical pipes
- commercial pulsation attenuators
- diaphragm accumulators
As air pockets enhance vibrations, please ensure that the hy¬draulic system is properly vented.
