Look who i found on the top of Bretton Woods. Bryan Warren Bryan came to support Tripoli Mechanical and assist at the SkiNH Tradeshow. Talk about going full circle. What a great day it was.

I know it's AI, but it is good information for those snowmakers that went through Ken's class.

Why Engineers use 4–20mA instead of 0–20mA

Because in instrumentation:

0mA does not mean “zero.”
0mA means something is wrong.

In a 4–20mA signal loop:

4mA = Valid zero process value
20mA = Full-scale process value
0mA = Fault condition

That 4mA starting point is called a LIVE ZERO.

It helps engineers and technicians immediately know the difference between:
• A real process reading of zero
• And a failed instrument loop

Example:

A tank level transmitter may be scaled as:
4mA = 0%
20mA = 100%

So:
• 4mA → Tank is empty
• 0mA → Broken wire, power loss, or transmitter failure

Without live zero, both conditions would appear the same.

Another reason is:
Many field transmitters are powered directly from the same current loop.
The 4mA baseline keeps the transmitter electronics powered while still representing the minimum measurement.

That is why 4–20mA became the industrial standard.

Another very successful Ski NH Snowmaking Training seminar. It was a collection of great clients, old friends, industry legends, and many new acquaintances.

This is a really nice event. Thank you Ski NH for including me.

This came up in discussion this week as a matter of fact. Here are some good details regarding the life cycle of a centrifugal compressor

Compressed Air Best Practices Magazine informs industrial sustainability, facility and energy managers on compressed air energy conservation measures deployed by compressed air auditors and technicians.

This is game changing. Pats Peak is usually the first area to open 100% in New Hampshire, on marginal years. This will only amplify and secure that status.

I find that this time of year is the best time to purge a lot of the unwanted and/or unnecessary things in your life. There's time between skiing and Summer construction, renovations, gardening projects to minimize your life of the items that are slowing you down.

Looking forward to seeing everyone at the NSAA Trade show . We will only be there on Tuesday, but will make the best of our time there.

East Coast is having the winter we deserve, don't you think?

Yes, we change oil also. Having the correct equipment makes for a quick fill, no mess, no contamination during the filling of the sump. BTW, it only took 8 minutes to fill the sump on this 1ACV. It took longer to drain and roll the hose back up.

This conversion included cleaning the sump to my specs. We pulled and drained all the hoses. We drained the oil cooler. We installed all new o-rings on the Parker fittings.
