Greate information in this video. Is there a link somewhere that I can download your Resistance Check Spreadsheet?
Thank you sir....god bless you....keep posting knowledge.....i really appreciate your hardwork...
How much is this kit?
Hello buddy, can you provide this spreadsheet?
can i use 8 mm probe to measure radial vibration of a 27 mm nickel alloy shaft?
Say, I am using the same valve but I have been given values to start the valve travel at 11 and 13 psi as my full travel. Should I adjust the spring tension first according to these values or should I do on the positioner?
The actuator should have a rated benchset and travel distance. When the control valve assembly was engineered, the actuator specs were selected based on the force required to operate the valve. This test verifies the actuator performs according to the original design. The positioner reduces the error that is a result of mechanical friction.
Thanks
Need some videos of repairs out in the field
Im having issues with a valve currently for leaking by. Hard to find the right kits or someone is not getting the right info for them. Is there a website or something to find the right kits? Based in west texas.
Emerson owns Fisher Valves. From the Emerson website you can find the local business partner as well as drawings.
Simple explanation, but hard to find it. Do you know any supplier I can buy proximeters from? I am located in Brazil.
I don't know. Baker Hughes owns Bently Nevada and they have a global presence. I'm sure there is a local representative. I would check their website.
Hi. Where could I get your excel table ? I would like to get it
Build it in excel. I show all the necessary formulas in one of my videos.
Thank you Sr. I'll do it
Can you provide exell sheet formula
Your email id please send
PLEASE... Can you provide excel sheet? Thank you very much! +++
What is tha input and output radial axial vibration plz answer
I am not sure what you are asking. Can you provide some context?
Like Video.
NICE JOB 👍 WELL EXPLAIN
Simple to the point explanations, thank you.
Thanks sir, it is a very informative vidéo with a clear explanation
where can I get the test sheets?
Can you provide excel sheet? Thank you very much
How does the eddy current generate in the metal? Does the varrying magnatic field has something with it?
You are correct
WOULD YOU LIKE TO SEND THE TALEBA FOR SENSOR CALIBRATION
Good exlonation jim,thanks.
Dear sir. I have two probes with different part number, PN: 86691-08065-0435-25 and PN:86691-09246-0435-25. I only know they are 2.5 m length but i am not sure they can be used interchangeably. Is it possible? What are their differences?
I don't have that manual, so I cannot say for certain. From a performance standpoint it should work. Difference will be in the custom features. Such as mounting options, length of armored jacket, etc..
Very good explanation, now I have a better understanding of Proximity probes.

Jim, where do you get the values for Peak to Peak travel and Measured Value?
I posted videos explaining how to perform the dynamic and static tests.
hello, when i connect the power supply 24VDC positive to the com and negative to the Vt(-24 VDC) it creates an alarm on the power supply and shut down the power supply. Please advice on wiring?
Power to com and -24. Output signal to out.
Thank you very much for the information, although I have a question, at minute 2:24 you put the value of 1 in the voltage column. why 1? What shouldn't be 10mil*200mV= 2V?
The response rate of 200mV / mil is only valid within the range of linearity. 0-10 mils is outside this range.
Best video on youtube!
How tight should the jams be tightened. What are the risks of not setting the jam nuts?
The jams keep the connection block in place In most applications, the feedback arm connects to the block. In some cases, even a slight rotation can create feedback error or loss of position indication.
What do you supply proximity power with? What kind of lines?
Excellent work 👍
Hi thanks for the video ! We bought a couple of these fisher control valves and we noticed that they don't all have the same bench set values, what's the reason for this ? I also noticed that you did your bench set from 9 to 15 psi, so when will the valve start to move? Is it 9 psi or 3 psi?
The bench set is engineered to operate the valve based on the process stream and will determine the pressure required to open the valve.
@@jimdiggins101 thanks so much for the Response! Atleast now I know that I didn't buy the wrong things 😃
Dear Jim thanks for video, I only have two questions, at the end we obtained values that were out of tolerance, right? And this was probably because we use other extension cable model, right? In advance thanks for your response! And good job!! 🤘
Correct. Incorrect length is the most common cause of error
Excellent!Can you provide excel sheet? Thank you very much
Thank you for your video. I have a confused question " Can vibration monitoring module supply +24VDC and -24VDC ?"
Are you referring to the proximitor card on the bently nevada monitoring rack?
@@jimdiggins101 Yes, Sir
interesting...
I seen some valve bodies have a line on it instead of a flow arrow? Is the line an indication for flow?
Some have a line on the body that has a downward angle, which represents the flow path through a globe valve. That may be what you are referring to. This alone does not indicate flow however, but for general service, you install with the angled downward part facing up stream so the flow enters below the plug and flows up through the port.
@@jimdiggins101 thanks for the info.
Excellent
Thanks
Thanks
thank you
You're welcome
Thank you!
Welcome!
Hi...Mr Jim... thanks for this informative video...kindly could you provide spreadsheet for me...
Hi jim diggins. Why is the voltage value according to the datasheet approximately negative -1 to -17vdc. But you take the positive value 1 to 17 vdc
Voltage is a potential difference and the polarity of the voltage has no bearing on the measurement. Use negative voltage if you like.
Excuse me sir. My name is agus. I have some question related with vibration system. 1. Whats the function for minus DC power supply? 2. Whats correlation between DC power supply and AC power supply which generated by probe?
Answer 1: The polarity doesn't matter unless you are a transistor, which in this case is why the polarity is reversed. For the purpose of understanding how it works, it makes little difference.
Answer2: Think of the AC as DC with a wave. Normal AC changes polarity, this doesn't. You just have to switch a meter to AC to measure the dynamics of the sinewave that is created. It's AC with a voltage bias.
