How to find the right transducer without having the part number?
« on: November 19, 2015, 04:32:25 pm »
Hello everyone,

I am repairing one of our tools, and the replacement is expensive. Unfortunately, I was impatient in waiting for my desoldering gun. (That I decided to pick up after seeing Dave use one often) I used a hot air gun to desolder it.

Well well well... The back of it melted, I can make out 3 characters, and the rest is toast.

I was wondering what one does in this situation? Do I attempt to order one, solder it on and cross my fingers? Is there a way I can test what I have?

I did not NECESSARILY damage them, the back is melted, but I assume it might still be holding a vacuum and be working...not sure how to test one?


This site had a few of them. http://www.mmselectronics.co.uk/smtspd.htm


Besides testing it, I figured I could read the machine specifications and operating pressures and make an educated guess on what the sensor ranges SHOULD be?


My last hope was finding a broken one of these, buying the board, and desoldering the sensor (properly) and then reading the back of it.


All and any information is appreciated in this case.

I will bump this up one more time, I can't get my hands on a used one so I am going to just try to replace this one with a guess and cross my fingers.

So I found it.


How can I test my current sensor to try to determine which one I have?

Absolute or gauge pressure, and the psi range?
