Guidelines for Selecting Proximity Sensors for Different Applications
In industrial environments today, several processes depend on system monitoring to make sure the process is efficient and the quality of the products. To obtain expected results is reliant on picking the suitable sensor technology for the application. To hold these demands, the sensors should be reliable, flexible and durable, without considering the environment. The right selection of sensor should include careful deliberation the sensor’s suitability, limitations and capabilities for the proposed application.
The various ranges of sensing capabilities of sensors is because of their versatility and high-level functionality. The standard proximity sensors are ultrasonic, capacitive and inductive.
As they perform very well in different applications, proximity sensors are suitable for several industries such as building and construction, discrete manufacturing, pharmaceuticals, oil and gas, chemical processing and food and beverage.
Proximity sensors are essentially non-contact devices for detection. Proximity sensors are able to detect an object without the use of contacts, unlike the standard sensors that must use a switch, mechanical switch or a plunger which should be pushed along a moving target so that it can capture an object’s presence. It is this non-contact design that protects a sensors integrity and boosts quality products because it does not subject equipment or material sensing to unimportant engagement. Proximity sensors are made to offer repeatable and accurate operation on high-speed conditions. Proximity sensors operate at high speeds above 5,000 Hz making them able to handle most of the fast-paced industrial applications.
Proximity sensors are accurate, which is calculated within 0.001 in. that makes them able to provided the expected accuracy to sustain effective production.
Proximity sensors in the market today are durable and flexible. There are some sensors that are available using several IP ratings that ranges from clean environments to extreme temperatures or washdown conditions. Proximity sensors come in different sizes, housing and mounting options that assist them in providing versatility and flexibility in their applications.
Through proximity sensors, most challenges of sensing are solved. Using the right proximity sensors an application’s downtime is reduced, reduced maintenance requirements and efficiency in production boosted. Understanding the different principles of operations, capabilities of performance and suitability of an application of different types of proximity sensors allow manufacturers to use the right sensors for the correct applications.
Proximity sensors that are inductive are able to detect metal objects even if they are non-ferrous or ferrous. Proximity sensors can be used to detect the presence or absence of parts, application positioning, and counting objects. The reliability of inductive proximity sensors makes them reliable because they are robust.
