Good choice on the Emerson, did you buy accelerometers and data collector? What about vibration software? The next step is to get some training on how to analyze the data. Emerson has a large campus...

For a quick and economical solution, Goulds Pumps has a wireless bluetooth single axis model called i-ALERT. I bought a couple of these mostly out of curiosity and found them very accurate when...

Take a look at the CTC brand AC230 series (www.ctconline.com). I haven't used this particular sensor, but have used many CTC single axis sensors and can tell you they are a great product and their...

I've been reading and hearing that the hopefully soon to be released Covid vaccine will require cold storage and transportation. The one that really caught my attention was the one that Phizer is...

I admire your thinking, but there a few drawbacks to monitor a hermetic compressor using vibration analysis.

I am a level III vibration analyst and worked in equipment reliability several years...

I, or rather my employer, just bought a UE Systems digital ultrasonic tester. Very cool tool, they have a low level pressure and vacuum sensor that will detect a very small vacuum leak. They also...

I've never been one to accept things at face value, or anything that I'm interested in anyway. Usually there is a good reason equipment is built the way it is. Manufacturers are challenged with...

Yes I can quantify that. These figures came from engineering tool box. The rating is based on (BTU/(hr x deg> x ft)

Stainless steel 7-26
Low carbon steel 31
High carbon steel 17-21

I'm doing some preliminary research on system replacement I plan to have done this fall. It appears that every manufacturer I have researched uses stainless steel heat exchangers in their condensing...

Thanks vstech, I have been in homes with radiant heat and it's like being wrapped in a blanket. Do you have any recommendations on which brand to use? I see that Schluter is making a system that goes...

This might be the wrong forum for this question, but I'll ask anyway. I'm planning a master bath renovation and want to install underfloor heating (electric) beneath the tile. I have always been an...

I returned to my hometown for a couple of days to visit family over the holidays. During my trip, I dropped in on an old pal I had not seen in many years. He and his wife are still living in a house...

If you haven't noticed, you've touched on one of my biggest pet peeves; home inspectors. Several years ago my wife and I sold a house and the buyers hired a home inspector. Our realtor called and...

Have you ever wondered why when you close on a piece of real estate the only people in the room are you and the lawyer? If you went into closing with a stack of $20 bills and paid everyone that got a...

Shiny metals like copper, aluminum, galvanized steel are tricky for any thermal imager. The quickest way to set the camera is using plain old black electricians tape. Put a small piece of tape on the...

I have taken both Level I and II thermography training through Infrared Training Center. ITC is owned by Flir and offers week long training sessions at numerous locations across the country. They...

The only experience I've had with Flir's meters are the ammeters. The higher end Flir imagers now have Bluetooth capability as do their ammeters. This feature allows a professional thermographer to...

Awesome job on locating those 3 wall sconces in the bathroom. It's really easy to miss and make an installation like that look like crap. I learned a little trick years ago that has helped me a lot....

The Square D "QO" series are about 30-32 in/lbs for up to a 30 amp breaker. All manufacturers list recommended torque either on the device or with the instructions. Try an experiment, tighten down a...

That does look like one or more loose connections. A neutral is a current carrying conductor while a ground is for carrying renegade currents away safely. Every electrical equipment manufacturer now...

Hi Teddy Bear, I hope you read this post. I have found a wall mount CO2 sensor that I like. Honeywell makes some but you have to configure their range with dip switches and select a range of their...

I ran my data logger test for 72 hours and found that the furnace cycled 3 times in just over 1.5 hours and that's with outdoor temps in the 30s, I feel very good about that.

Two additional things...

Thanks to valuable information I've gleaned from this forum, I now understand what a good CPH rate is for air conditioning, but don't recall seeing anything for heating.

After looking at our...

I'm planning to replace 18 year old gas furnace/AC systems next spring, that will include a fresh air intake. I am taking some accurate measurements of room sizes, outside walls, and glass area, and...

Thanks, teddy bear, I was hoping you would respond. The truth is that I had a Comfort-Aire WHD-130 installed a few years ago that does a really good job controlling humidity, but does not have the...

I am planning to replace my 18 year old HVAC systems next spring and want to incorporate a fresh air intake as part of the install. Although I haven't started the bidding process yet, I have talked...

One of the many valuable lessions I have learned from this site is how leaving the blower in the "on" setting during AC season will increase humidity. I fully understand how the A coil and pan have...

One of my home maintenance jobs this fall was some overdue work to my windows on the exterior. I gave them a good cleaning, re-caulked them, applied 2 coats of water sealant to the brick sills, and...
