Thanks for watching! Exposing the outer insulation wire to air would not affect the EGT reading. The tip of the EGT sensor is the point at which the temperature is measured, temperature changes on other parts of the sensor such as the outer insulation wire shouldn't change the reading.
@@HGSIndustries thanks for clarifying that for me.....i ask this question because I have 2 egts and the wires have been rubbing up against each other and inside the insulation there is two wires....the insulation is completely gone and eaten away at 3 small tiny wires of 1 of the 2 main wires....I think this will effect the EGT reading ? Is there a test I can do on a multimeter? Sorry to ask but I've tried to find information online even on forums but I can't find anything concerning the 2 main wires going into the EGT. One person said it shouldn't matter another person said it will matter?
@@jmoore9806 if the EGT signal wire insulation is completely gone and both signal wires are exposed down to the bare wire (metal conductors are exposed), and if these two bare wires are touching each other or any other piece of metal on the engine, then yes you will have a short and this will most likely cause errors in the temperature readings.
Nice video! I have a thermocouple that I bought from Amazon and I was wondering what type of wire can I use for the extension to connect the pid and thermocouple
Glad you liked the video! Best practice is to use extension wire that matches the thermocouple Type. For example, if your thermocouple is Type K, then use Type K extension wire. This should also include the connectors you use to join them together. Join a Type K thermocouple to Type K extension wire using a set of Type K connectors.
This is very useful, thanks. Can I replace old 'k 'type with new 'j' type without changing PID(temperature controller). (Process temperature 0-200 deg celsius )
Only if your PID controller is compatible with Type J thermocouples. Many PID controllers will work with different thermocouple Types, but there are some that will only work with one thermocouple Type. If your PID controller will work with different thermocouple types other than just Type K then you'd need to change the Controller's input type setting from Type K to Type J. To perform this task we suggest you consult with the PID controller's user manual or the manufacturer.
I have a multimeter with a type k thermocouple. It’s a flimsy little wire. I also have a few spare thermocouples used in kiln that are type k. Can I use one of the larger kiln thermocouples with my multimeter. Will it read the temps the same as the little wire one ? I want to use it to test my kilns when I suspect a thermocouple is starting to go bad, but I don’t think the little flimsy wire one would hold up.
A nice video but I have a question regarding your positive and your negative. I know the negative goes to ground but does the positive go to constant hot or key on? The reason I'm asking this it's because I'm unsure how this thing keeps the memory
Gauge power positive can go to key on. The gauge's settings are stored in a non-volatile memory so settings are retained even if completely powered down. Thanks!
