How To Choose The Best Level Switch
A level switch is a technology that is used to monitor the level of liquid within a tank and make sure it does not overflow. The switch works as a sensor that monitors the liquid level. Once the sensor is triggered, the switch automatically turns off. This makes it highly efficient, as it does not need a human being to operate it. This piece of technology is important in many sectors, but if you want to get the best out of it, you need some help. There are some factors to be considered before choosing a level switch, and this article will highlight it.
1) Material selection
The switch can be made with different materials; the switch you will get is dependent on the type of fluid that is in the tank. Certain materials are not compatible with some fluids. If you use an incompatible pair, you will end up damaging the switch, and if the switch is damaged, it cannot work. There are various types of materials, and some include:
a) Polypropylene: This material is suitable for alkali, detergent, and acids. Also, it can accommodate oil and water.
b) Stainless Steel: This is used for medical applications and is also good for food applications. Other materials include Polyphenylene sulfide, Nitrophyl, and some other materials. If you get a bit confused about the best material to use, you can consult a compatibility table that will help to make the best choice.
2) Arrangement and style
The arrangement and style of the switch is very important, so that you can get the best out of it. The arrangement and style are dependent on the tank, and the application you want it to run. You should make sure that the arrangement makes it possible for the switch to reach the fluid in the tank. There are two styles that can be used in mounting the switch: it can be mounted horizontally or vertically. If mounted horizontally, it is placed on the sidewall of the tank or application. If mounted vertically, it can be placed on the top or bottom of the tank. You need to consider the style that will be good for your application and that is compatible with your tank type.
3) The wiring
The switch is wired using cables and often these cables go through the fluid. So, when picking switches, you should look for a switch whose cables are made with the appropriate materials. Which material should be used for wiring is dependent on the fluid that is contained in the tank. There are various types of level switch cables, so you need to make sure the one you choose appropriate for your tank.
Choosing the best and most appropriate level switch is not a very difficult task. All you have to do is to put the above tips into consideration and take the necessary steps. If you do not consider the material, the arrangement style, and the cables that are attached to the switch, you will end up making the wrong choice. But with these tools, you are equipped to make the right choice.
