Proximity Sensors

Yep. A lady called "Globalspec" can do that. Go to the toolbar above, click Products and Suppliers, and follow the Yellow Brick Road from there.

still did a search on Globalspec before my post , I just wanted to complete with your expertise , giving me some name of manucaturers making high spec "proximity sensors" ( photo,magnetic,inductive,ultrasonic …) , willing to find out worldwide

Google

I strongly suggest that you learn how to use a search engine or, as suggested, use the resources of IHS Globalspec at Products & Suppliers.

All of your requests for information are readily available either here or the internet.

I'd go sonic

Here's a link: Sonic

Is this what you had in mind?

more like this, no cheese

Go IR sensors or laser type proximity, your conditions wont have interference with those.

the OP clearly stated he has a very high temp application and your suggesting IR?????????????????????????? you're an idiot who should stay silent

It may just be a match made in Heaven.

Think about it.

In your formers posts you say:

"we design vacuum pumps for apllications in semi conductor process , coating ..."

"search person able to explain ( technical & process ) types of valves , sizes used in nuclear power plants , number of valves used ( motorized , air operated , manual ) .."

"could somebody give access to complete repair manuals of recently launched ( 20060 -2007 ) forklift models ( electric powered & with internal combustion ) , allowing me to understand details how work "

"does somebody know about the motor driving the CPAP ( continuous positive air pressure ) air turbine ? specs ? manufacturers of this motor ?

• same question for pressure sensors ?" but you have no clue how to find the products/answers you need!

You have never indicated that you have put forth any effort to find the answers to these questions on your own.

ALL of your questions demonstrate a lack of ability or desire to find these answers independently.

You were given a great source Products & Suppliers.

Now use it!

Google high "temperature reed switch". The first hit shows a product good from -270°C to +400°C suitable for both high pressure and high shock loading. "High temperature and cryogenic" are relative terms, be specific about your needs i.e. " A switch with operating parameters between X°C and -Y°C" or "up to a pressure of Z bar" Secondly don't limit yourself to a specific type of switch. Proximity switches contain electronics which restrict their use to a narrow temperature range. Reed switches, mercury switches and mechanical limit switches all work over a much wider range.

ok thanks , searching proximity sensors / switches manufacturers with temperatures > 200° C for first application , second application Temperature > 400°C

do you know & have experience with manufacturers ? who ?

I have used Honeywell HR series switches on a steel production plant at 270°C (they are rated up to 315°C). For reed switches contact Hamlin (You should study their application note AN105A). Generally I avoid putting any electrics at above 100°C if possible because you need over sized cable with high temperature insulation, porcelain terminal blocks, crimped connections, special mounting features and expensive switches, motors and solenoids. Overall it is normally easier and cheaper to find a way of taking the electrics away from extremes of temperature and vibration. For high pressures the greatest problems are encountered sealing cables where they penetrate the high pressure shell.

For more detailed information E.mail me privately with your full application requirements and I will quote you my consultancy fee rates.

For starters take a look at Omega Engineering offerings as they carry and have access to a very broad spectrum of high quality sensors and controls from several different manufacturers and they provide excellent free technical support for ease of application.

Emerson Rosemount, Endress Hauser, Vega, ABB, and Siemens, are a few of the manufacturers that make high quality instrument devices that will monitor, report, and control a broad range of process variables.

Sick (a company name, not an adjective) make every kind of sensor you can think of, including some for high temperature operation.

They have a product selector matrix that can start you off, but I suggest calling them in your country, because 200C is a serous challenge and they will need to be consulted. Whatever you use will need to be remotely located, because no electronics can survive in that environment. https://www.mysick.com/eCat.aspx go=Finder&Cat=Gus&At=Fa&Cult=English&Category=Produktfinder

thks

Give them their proper name please, Erwin Sick. It doesn't sound quite so bad
