thanks for the prompt feedbacks. dpc, u mentioned on the observation ports. what are those? would appreciate if u could provide me with the links to find those. actually i have another question. recently, we have a unit of ACB (Air circuit breaker) that burnt down due to loose connection at...

I don't seem to be getting any reply for this post. Perhaps i should refine my question. Actually I'm interested to know what is the safest distance away from High Voltage panels for IR scanning without having the risk of spark over, while not compromising on the image quality? What are the...

Good day, I'm interested to know what is the common industrial practice to scan HV panels? Appreciate your thoughts. KL

Hi, I'm looking for idea for a basic online monitoring system, whereby my requirement is to only trend the overall levels. No spectrum required. I need to monitor a pickup roll both locating and fixing ends real time. However, I'm not sure what kind of hardware I would need for this setup. My...

does anyone know what's the relationship between vibration signal transmissibility/intensity versus material thickness? Is there any literature regarding this subject? the reason for this is that recently i have a bearing failure on a machine whereby the bearing housing is quite thick. the...

thanks matthew and sreid for your replies. sreid, actually i'm seeking for the equation for a double cardan joint. is the equation the same? Rgds KL

Hi, What is the equation for cardan error (relation between the input/output angles and the input/output speed). I'm trying to establish the misalignment tolerance for u-joint but before that, I need to know how the input/output angles of the u-joint affects the speed. Thanks KL

thanks to electricpete and flacrkr for your replies. Anyway, flacrkr, the freqs that u mentioned above are based on what rotational speed? What are the multiplies of these freqs (at 1RPM)? I'm particularly looking for freqs at 286RPM. Thanks a million

G'day, Can anyone please provide me with all the bearing defect frequencies for NTN UK216 bearing? I can't seem to find it anywhere.. Thanks

I have a pump with high BPF spike and harmonics symptom and this symptom started to appear since early July. I trended the symptom and requested for a impeller check last month. However, the impeller and wear disc are in good condition but the measurement still indicating the same symptom. In...
