Different sensing technologies are equipped with unique capabilities allowing them to perform well in a specific area. Do not hope for the correct reading when you have a photoelectric sensor in an environment full of dust because that interferes with the receiver. However, ultrasonic sensors will serve you well because they work just fine whether there is dirt or dust given that sound waves still penetrate areas which are dusty. These sensors are utilized in many different places but they are highly needed in the food and beverage industry, the agricultural field and by people who are working in packaging. No matter what you need the ultrasonic sensor for, you should make the right choice. In order to control the sensor, there should be different modes and you do not want to make the mistake of taking this for granted. You will probably get a sensor which has been equipped with 3 modes which include the diffuse mode, a thru-beam and retroreflective mode. The most popular one is diffuse.
Once you ensure the modes are going to serve your objectives just fine, you need to move on to the housing. They come in different materials, sizes and even shapes. The ultrasonic sensor housing that will serve you well should be picked out based on the place you will be working from not to forget the application you will be putting the sensor through. Many of the sensors you will find will have a flat pack housing, a cylindrical one or even one that is made in a cubic shape. Regarding housing materials, you will have to pick either metallic or plastic material. If you want a sensor that is durable and can hold its ground in high torque, a metal one is the best. If the working environment is not an important factor, a plastic housing should do and the better part is that you will not have to use a lot of money.
Note the kind of output type because it is important in the work you will be doing. There are two output types: switch point and analog. Think about the work you will be doing in order to know the choice you have to make. The range of measurement of the sensor is something you should keep in mind too. If the sensor has a smaller transducer, the operating range will be small as well. Your budget will affect your choice too. Do not assume that what is priced higher is the best thing for you but rather think of functionality and durability as well as the budget. When you take the time to review what is on offer and consider your objectives and budget, eventually you will come up with something you will be happy to work with.
