Everyone has their own idea of what an industrial sensor is and what it does. But you might be surprised at how many of these ideas are inaccurate. Here are several misconceptions about industrial sensors:
1. All sensors are equal in strength and durability
This could not be any further from the truth. Every sensor, regardless of the technology, possesses different restrictions. IP ratings are a great example of this and let the customer know how durable the industrial sensor is. The higher the IP number, the more durable the product will be. Extreme conditions may require the use of NAMUR for extra protection of the sensor, which allows for the detection of a harmful substance while the sensor is in the safe zone.
2. Sensors? I only use them for my garage door
Sensors have a larger role in our lives than simply for domestic use. They are used in garbage trucks to pick up your trash, to sense your car in the carwash, to detect the level of soda in a bottle at the factory, or in printers to detect excess paper prior to a paper jam. And do you know what that little black square on the paper wrapping of your butter stick is for? Actually, it is there so when a contrast sensor sees the square, it sends a signal for the paper to be cut. Cool, right?
3. Sensors can only be used to detect the presence or absence of an object
Of course not! Although there are inductive sensors that do detect presence and absence, there are other product lines offering a wide range of functions. Need to detect rotation? Rotary encoders will do the trick! Photoelectric sensors are able to detect a wide range of properties, such as variance in color, UV properties, distance, or label detection. Ultrasonic sensors can be used to determine distance or the amount of product in a container. In mobile equipment applications, an inclination sensor can be used to measure angle and tilt.
No matter your application, whether it is safety or object detection, there is an industrial sensor for you!
