@ February 20, 2014 5:08 AM in Tom Schwarz has passed awayI attended seminars at Wallace Eannace, Wales Darby and Firedragon with Tom, real nice guy and very knowledgeable. Rest in Peace Tom
@ February 14, 2014 9:03 PM in New Seminar on AIR!Professor, are there still seats available? I still waiting to see if I'm able to make it, along with a couple of others from my company. Trying my best to make it.

Hopefully the attachment comes through,
Gas Pressure Tap Fitting -
The #240 Gas Pressure Tap Fitting is used
to quickly connect a 1/4" manometer hose to gas valve (1/8"-27 npt) -
one pair. The fitting fits onto most gas valves and pressure regulators and
allows you to quickly check and adjust the pressure of the valve or regulator.
Once the correct pressure is set a simple turn of the fitting closes it off,
read Firedragon Field Note #15 [size=12]here[/size]. The #240 also can speed your day along by using it
as a pressure fitting for your draft gauge or manometer. Just drill and tap an
1/8" hole into smokehoods, fire doors or anywhere else, mount the #240
once and just open it when you need to take your readings.
Buy them by the bag full #241 and save time and
money. Use our [size=12]#140
Minidriver[/size] to quickly open and close
the internal valve.
Gas Pressure Tap Fitting, 10 pairs of 240
NOTE: All of our adapters and testers are supplied ready to
install and use and are constructed from heavy duty brass for long life and durability.
@ January 15, 2014 8:10 PM in ManometersFiredragon sells them on his website, they have a small screw inside them so you can leave them on the gas valve and turn them on or off

@ June 13, 2013 3:25 PM in SHEMA trap ratingsFrom my supplier:
SHEMA ratings only apply to an F&T trap, Steam Manufactures Association (SHEMA) providing for the continuous elimination of air when the trap is operating at its maximum rating. No safety factor need be applied. Actual capacities are significantly greater than SHEMA rating indicates.
@ June 13, 2013 8:59 AM in SHEMA trap ratingsDave, I reached out to my trap Rep and he asked his guy at TLV and he mentioned that the SHEMA is a very old rating system for trap capacities that is no longer used, there is a conversion but if you could tell me your application/product that might help him find the info faster
@ May 8, 2013 5:06 AM in RIBu1cI had posted this on Oil Tech Talk a while back. Hope this helps.
I have a RIB2401D on our work bench , which consists of one Relay, and a Double Pole Double Throw switch (2 normally open switches and 2 normally closed switches) you can supply the Relay with either 24 volts, or 120 volts to energize the relay which will then switch the position of the switches from their former position (i.e, if a switch is N.C, then when the relay is energized it will switch to the open position) The voltage that powers the relay portion does not "touch" the switch section, they are completely separate, all it does is energize a coil of wire and creates magnetism and when it does it causes the switch contacts to reverse their position, so since the voltage for the relay does not supply voltage to the sets of switch/switches, you have to bring your own source of power into each switch (either 24v, or 120v). I guess you can call the set/sets of switches in a RIB "Dry Contacts" which means no juice/no power. A switch is just a switch, think of the switch/switches inside of a relay like a wall switch (toggle) it is either open (no power allowed to go through) or closed, allows power to pass along) So if you have say a T-stat tied in to control the 24v side of the relay, when the stat calls for heat it will close a switch inside of itself to send 24v to the relay coil and energize it, now your switches inside of the relay will reverse their positions, so I had a 24v EP Switch hooked up to one of the NO switch's on the relay, and I got that power from the secondary side of my transformer, so once the t-sat received a call for heat it powered the relay coil and closed of my NO switches that had 24v waiting on one side of that switch, so once that NO switched to the closed position it sent 24v to my EP switch and opened my my Pneumatic damper. Hope i made some sense. I have a crude mock up on our bench with the RIB controlling a couple of different loads with both 24v, and 120v, the best thing to do is get your self a couple of these relays and start testing them with your multimeter to see how the switches operate when the coil is energized, and get yourself some copies of Carol Fey's books, she great at explaining the way relays work.
