TFLS系列 音叉式料位开关*适用于粉体物料和颗粒物料，特别是低密度物料的料位监控。它采用压电水晶带动音叉以其自然频率振动，当音叉接触到物料会阻尼改变振动，开关会动作，而当物料离开音叉后，开关会还原到原有的位置。TFLS可选开关状态的故障安全模式。它不会受到系统中物料输送，马达等振动的影响，并且可以任意方向安装，可定制加长的音叉用于槽罐的顶部安装。TFLS料位开关无需校准，容易使用，它不带任何机械移动部件，不需要日常维护。它不受物料的介电常数的影响，能用于当介电常数低的物料不适宜用电容式物料开关的场合，特别是用于混合物料的场合，和物料干湿度经常变化的场合。音叉料位开关也特别适合于物料密度很低，无法采用旋叶式料位开关的场合，它也能用于监控液体中颗粒物料的液体固体分界面。

LTC系列 倾斜开关料位控制器带有逻辑选择开关，还可以调整延迟时间。 逻辑选择开关的作用是决定继电器什么时候动作或解除动作。第一种方式是探头垂直时继电器动作，当探头成角度时继电器解除动作。第二种方式的动作正好相反。继电器延时动作的功能能用于垂直或角度的状态，以避免误动作。继电器在延时完后会解除动作，在失电的情况下，继电器也会解除动作。

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.
