Re: thermometer range
Harry, The strip heater element is a resistance wire woven into a cloth like flat weave. It comes in various lengths with one closed end and the other with an electrical cord and a 110v plug. You will have to make a board about 6" wide by the length of the strip. The board can be a base of 1/2" plywood 6" x length. Add two 1/2" plywood strips 2 5/8" x length on the base board. this will leave a channel 3/4" wide. Form a piece of heat resistant material such as 1/16" asbestos sheet over the top. Lay the strip heater in the channel and you are in business. Avoid letting the heater be above the channel. Do not make touch contact with the plastic. Norman New Jersey > strip heater.

Re: IR thermometer range
Hi Guys, I have been using an IR thermometer sold by Radio Shack for approx $40 to measure Gauge 1 casing and paint surface temps etc. Measures up to 500F or C equivalent. Very small and compact. Ideal for measuring those engine surface temps. And no toy. You can pick up some very usefull (and surprising) info by using one of these. Tony D.

RE: IR thermometer range
I would assume since the area is so small, no difference would be detected even with a very good meter. Until the boiler runs dry I would suspect the heating to be very uniform. Trying to get something to fit in the area to read the probes would be almost impossible. Getting to know the engine, how it needs to be watered and fueled during operation would probably be time better spent. My operation of the Excelsior is to pump water in when the pressure guage reads 40 psi and stop refilling when the pressure drops to 20 psi. The engine will start and the pressure will quickly return to 40 psi. Repeat every so many laps until I have had enough fun.

Re: IR thermometer range
Years ago, Little Engines sold a temperature gauge which mounted on the backhead of the boiler and had a probe that went into the boiler some short distance. The theory was that it would give you a heads up of water level or fire condition. I guess I have wondered how on earth one could keep track of the water level in a Ruby boiler so that running could be extended. Does temperature at different locations of the back head offer a solution in some way? - Original Message - From: "Ciambrone, Steve @ OS" <[EMAIL PROTECTED]> To: "Multiple recipients of sslivesteam" <[EMAIL PROTECTED]> Sent: Tuesday, July 15, 2003 11:28 AM Subject: RE: IR thermometer range > Mike, > I do Environmental testing for aerospace for a living which includes > temperature testing and really do not see the need for such an item.

thermometer range
Mentions of temperatures remind me, I have a few items to form from 1/8" acrylic and I read that I need to use what the plastic people call a strip heater. This appears to consist of a heat tape approx 1/2" wide with a max temp range of around 300F, and a plug. Does anyone know if this type of tape can be bought in rolls or something I can cut to length? Regards, Harry
RE: IR thermometer range
Mike, I do Environmental testing for aerospace for a living which includes temperature testing and really do not see the need for such an item. It would be a nice to know number even interesting but what real use would it be?IR measurement has its problems, if you want to buy something to measure temperature, get a Digital Multimeter with a temperature probe. It will be half the price and you can use it for other things. The temperature probe will allow you to measure temperature in areas where the IR meter will not fit.

Re: IR thermometer range
Heat treat monitoring in what capacity? 1000F is well below any range I've ever encountered for heat treating (with the exception of aluminum alloys). Sounds like a fun "toy", but I'm not sure about it's real world usefulness on our little locomotives. Many people on this list are better informed than myself on those aspects. - Trent Mike Eorgoff wrote: > Since 1000F is less than what is needed for > heat treat monitoring and some brazing, would the 600F model be high enough > to determine non-flame temperatures on our small models.

IR thermometer range
Enco has a sale on IR thermometers. They have two max temps for sale, 600F & 1000F at increasing prices. Since 1000F is less than what is needed for heat treat monitoring and some brazing, would the 600F model be high enough to determine non-flame temperatures on our small models. Like how hot is the flue gas, how hot are the cylinders, how hot is the outside of the boiler. Basically, everything other than the flame temperature. Mike Eorgoff
