Nice Hub Temp Display

[Beavinator]

I was recently searching for a Hub Temperature Gauge and I found this really nice looking one.

does it have temp controlled alarm? I think a temp alarm would be best so you dont have to look at the screen while riding at speed

I dont believe that it does doc but I wanted something that was fairly small in size. I will place it in a spot that is easy to glance at while riding so its not a big deal that it has no alarm.

How do we extend the range of the lead, and where do you guys put the probe? Thanks.

The wires are usually just two thin wires, so you cut and extend them. THe further you make the lead technically the less accurate the tempmeter becomes, but it doesn't have that much effect. The probe is usually installed inside the hub, right next to the windings. But the wires are very thin, so getting them through the axle is usually no biggie.

EDIT: for the Aussies, Bunnings stock a pretty good $20 BBQ temp probe that I have used with success. It is with a metal probe (ie, it is a stick with a solid probe coming out the end), you cut that off and remove the wires. I have used that meter with good success.

Linked this one in the 3-page "Temp sensor that's too cool not to share" thread....

these work well. the pic is of the older model, the new one has a hard clear plastic case, and you can adjust the voltage/temp alarms. Im using one atm, the probe itself comes attached to a small piece of PCB, witch is un-necessary as its the little IC (bout the size of 3 halls) can work on its own. As such its easy to pull it off the pcb and mount it directly against some of the windings. extending the wires has made little difference to its accuracy. I've also modded mine to have the alarm on a switch, so if it gets too hot I can switch it off rather than wait for the motor to cool down.

Biggest problem though is the LCD display is outright CRAP in sunlight, impossible to read, no where near bright enough. you need to create a cover with your hands and look through it to read it. works great at night though.

I still find a temp display of the axle temperature good enough to serve for anything less than racetrack use, or if you are pushing a motor stupidly up too steep hills.

Yes, it's reading a temp based on how hot the motor was about 5 min ago, but in "normal use" you shoudn't be running that close to disaster.

So I continue to use 10 buck automotive indoor outdoor thermometers. I put the sensor on the axle, tucked into the dropout notch, and then cover with a scrap of foam to keep wind from affecting the reading.

No worries about wires to the inside of the motor. Readout stops at 159 F, so it's about the time you should stop when you see HI TEMP on the display instead of a number. In "normal use" I rarely see anything above 120F anyway.

If you are really romping on the motor and know it, then you do need a real time display of the actual interior temp.

I run this one which has worked well... http://www.sureelectronics.net/goods.php?id=949

But if I ever get another, I will get this one... http://www.partshelf.com/taylor-9940n.html
Long leads, 150c temp, compact.

My cheapo BBQ temp sensor- $4 from eBay- is within 1 degree celcius of my expensive thermocouple at 110 degrees. I opened it up, removed the spear, put the temp sender under a winding and soldered a new lead in. The display is mounted on the handlebars so I can keep myself constantly worried.

It reads up to 300 so has plenty of range. No alarm but it updates temps quickly so you can see when you're getting close to the limit.
