TFLS系列 音叉式料位開關(guān)*適用于粉體物料和顆粒物料，特別是低密度物料的料位監(jiān)控。它采用壓電水晶帶動音叉以其自然頻率振動，當(dāng)音叉接觸到物料會阻尼改變振動，開關(guān)會動作，而當(dāng)物料離開音叉后，開關(guān)會還原到原有的位置。TFLS可選開關(guān)狀態(tài)的故障安全模式。它不會受到系統(tǒng)中物料輸送，馬達等振動的影響，并且可以任意方向安裝，可定制加長的音叉用于槽罐的頂部安裝。TFLS料位開關(guān)無需校準(zhǔn)，容易使用，它不帶任何機械移動部件，不需要日常維護。它不受物料的介電常數(shù)的影響，能用于當(dāng)介電常數(shù)低的物料不適宜用電容式物料開關(guān)的場合，特別是用于混合物料的場合，和物料干濕度經(jīng)常變化的場合。音叉料位開關(guān)也特別適合于物料密度很低，無法采用旋葉式料位開關(guān)的場合，它也能用于監(jiān)控液體中顆粒物料的液體固體分界面。

LTC系列 傾斜開關(guān)料位控制器帶有邏輯選擇開關(guān)，還可以調(diào)整延遲時間。 邏輯選擇開關(guān)的作用是決定繼電器什么時候動作或解除動作。第一種方式是探頭垂直時繼電器動作，當(dāng)探頭成角度時繼電器解除動作。第二種方式的動作正好相反。繼電器延時動作的功能能用于垂直或角度的狀態(tài)，以避免誤動作。繼電器在延時完后會解除動作，在失電的情況下，繼電器也會解除動作。

A unique, patented Magnetic Linkage isolates the electrical compartment from controlled product, reducing maintenance and improving sensitivity. The sealed switch compartment and sealed leads yield the utmost in reliable operation. A wide selection of diaphragms and switches is available with choices of flange or suspension mounting to fit your specific application. The dry level Ultra-Mag? Level Switch is extremely sensitive and very economical. The magnetic linkage makes this simple explosion-proof diaphragm switch the most rugged and reliable level control for a variety of products.Mounting Selection: A choice of either suspension or flange mounting is available to match your application. Flange mounting is the best choice for control of low or intermediate level in vessels containing granular product that does not "bridge", "rathole", or otherwise build up on vessel walls. Choose suspension mounting for high level in vessels and for better operation with "bridging" product. See below for more information on suspension and flange mounting kits. Note that the mounting configuration is represented by the letter "S" for suspension or "F" for flange which is the second digit in the part number.Diaphragm Selection: A wide variety of diaphragms is available to match product bulk density, flowability, abrasiveness and temperature requirements while providing maximum sensitivity. The best choice for vessels subject to pressure or vacuum is "breathable" fabric (P Series), requiring no venting. Non-porous elastomer (G Series) type diaphragms are the best choice for more abrasive product and broader temperature range applications. Venting is always required with the G series and if used in pressurized vessels, venting to the tank atmosphere is required to allow pressure equalization. A slide rule "Diaphragm Selector" is available from the factory to help you choose the diaphragm best suited to your application.Suspension Mounting is normally used for high level monitoring in vessels. For product over 20 lbs./cu. ft., the level switch (diaphragm face) should be located about 1/3 of the distance from the vessel wall to the point of entry of the product. For product less than 20 lbs./cu. ft., the unit should be located closer to the point of entry of the product, about 1/2 the distance from the vessel wall to the point of entry. Pressure required to depress the diaphragm and trip the switch is in the range of 5-15 oz in the horizontal direction (perpendicular to the diaphragm). Suspension mounting provides the easiest vertical adjustment capability, greatest sensitivity and best maintenance conditions.Suspension Assembly Kits: Pre-assembled kits are available from the factory, or you can build your own kits using standard pipe fittings. Pipes and fittings are normally galvanized steel, but aluminum and stainless steel pipes and fittings are available. Units pictured above are secured to a steel cover plate that rests on a rectangular steel flange welded into the top of the vessel. Aluminum and stainless coverplates and flanges are also available. Standard 48" long x 1" pipe provides working depth (WD) up to 48". Longer pipe (to provide greater WD) is available. GS Series switches have upper (L1 = 28" standard) and lower (L2 = 20" standard) 1" pipes, with a tee (for stilling pot) in between. A stilling pot is required to equalize pressure and keep dirt from building up behind the diaphragm. PS series require a 1/2" conduit in 1" suspension pipe for explosion-proof applications. The 1/2" conduit (56" standard length) is a standard part of the GS series assembly.

The Series PLS2 is an electromechanical level switch designed for level monitoring of bulk materials. The rotating measuring vane is driven by a brushless synchronous motor at one revolution per minute. As product builds up, the paddle rotation is impeded and the resulting motor torque activates the output switch and stops the motor. A spring mechanism reactivates the motor and returns the switch to normal state when the material no longer impedes the paddle rotation. A torque adjusting mechanism eliminates the need for different sized paddles. The PLS2 is designed with the industry standard 1-1/4" male NPT connection and unit can be side or top mounted.
