Inductive Proximity Switches for Sensing Metal Objects in Extemely HOT or COLD Areas

http://www.pantron.com/us/ege-inductive-proximity-switches.html
The German manufacturer, EGE Elektronik, offers special inductive proximity switches for high temperature applications. Focus is on TROPICAL switches which exceed IP 69K with a temperature range up to +120 °C and is optimally suited for corrosive environments.

Even higher temperature switches up to 160 °C are also offered.

EGE's highest temperature resistant sensors can be used in extremely HOT environments up to 250 °C.  These models are available with armored cables and external amplifiers.

On the lower end of the temperature scale are the POLAR switches that thrive in -60 °C.

Large switching distances up to 170 mm and sensors resistant to rolling oils made from PTFE, PP or PEEK are also available for the food industry. Intrinsically safe ex-classified sensors according to ATEX and compact dust-EX and gas-EX sensors complete the product program.

The "demanding environment" sensors offered by EGE are specially designed for harsh environments in which sensors are exposed to high electrical, electromagnetic or mechanical stresses. Stresses are not always included in customary inspection and test methods in the way that they develop in different production environments. Therefore, EGE has developed special test methods that are better suited to the use of sensors in critical applications. This has resulted in sensor designs that are suitable for use in almost any environment.

How to Equip Amusement Rides with the Right Sensors


The best types of sensors in an amusement park are the ones you don’t think about until maintenance time. Find the most reliable products and they will save you money and headaches all year long.

Evaluate each amusement ride individually. What type of sensing solution is currently in place? How well does it work? If it is possible to replace contact switches, otherwise known as limit switches, with a non-contact solution, it will greatly improve the uptime for that ride. Contact switches with moving parts wear out quickly, whereas non-contact sensors only need to be replaced in the event that they are destroyed by collision, Mother Nature, or extremely rough handling. Consult with a manufacturer or distributor of industrial sensors and ask them for assistance with your application. Any sensor company who is interested in doing business with you should be able to support the products and answer your questions.

If a new sensor is what you desire, the next decision is which type of sensing technology to implement. There are many sensors to choose from, but in the amusement industry, the top picks are infrared photoelectric sensors and inductive proximity sensors. A transmitter photo eye projects an infrared beam of light, which is invisible to the naked human eye. A receiver photo eye reports when it sees the beam and when it doesn’t and will pass a signal to the appropriate controller. Rides that require objects to be detected from a distance or in harsh conditions, like log flume rides, river rapids, and dark, smoky theme rides are great places for photoelectric sensors.

Try an inductive proximity sensor in areas where metal objects must be detected at close range. These sensors will only detect metal and their sensing distance is limited, but they are extremely tough and can take a beating. Rides like roller coasters, where the sensor may be mounted on the track and detect the metal in the train are good applications for inductive proximity sensors. Inductive proximity sensors are excellent replacements for limit switches.

Develop a routine maintenance schedule and replace all sensors in the amusement park at least once a year. This will ensure proper function and will keep the rides operating at their peak performance. Visitors will appreciate the ride availability and you will notice improved uptime and fewer replacements throughout the year.
