Thanks for a great instructional video! I have a bicycle floor pump, with a similar gauge, that I guess I must have dropped a few years ago. Since then, it has read about 15psi at no pressure. I have always just added 15 to the reading. After watching your video, I opened it up and was able to squeeze the curved "loop linkage" with a small pair of needle-nosed pliers to re-calibrate it to read zero at zero pressure. I then checked it on a tire pumped to 50psi against a new pump and it was bang on! Thanks to you, I feel like I have learnt and accomplished something today!

Very inspiring, it gimmes some ideas now about making some, calibrate them approximately following another one as a reference pressure gauge, and digitize the apparatus with some potentiometer, to plug that on a microcontroler for cheap.

Spent a considerable portion of my wage slave years in a fossil power plant in the Apple. There were large "steam" gauges in the various boiler control rooms with drum pressure brought right down to the back of the board. Woowie! By the time I retired in 2000 that was all replaced by local pressure transducers mounted locally with a 4-20 ma current loop output into various electronic "stuff".

Thanks for the description and explanation. I keep a gauge like this in my bike bag, after it got wet during a few rainy day rides it drifted away from zero PSI at rest. I recalibrated it to zero by bending the flat copper pipe until the needle landed at roughly zero. Still not sure how water affected it in the first but I guess something must've expanded and oxidized. Nor am I sure if my "fix" effectively made it accurate again. Waiting for a replacement to find out for certain. I only have one gauge that's compatible with my bike's preasta valve. Schrader shrader adapter, regular schrade valve compatible pressure meters never report accurately when used with a presta adapter. As a result I have to wait for a replacement presta pressure gauge to arrive before I know if it's accurate or not.

Hi LyleYes excellent once again. I deal with pressure gauges every day at work. mainly cheap ones. working from 0-15WC which is about 1/2 PSI to 10,000PSI. I design pressure washers. The low pressure ones are for gas pressure and the high pressure ones are for the water. Huge range and everything in between. The zero is normally done with the needle it is on a taper on the spindle and that little loop is to adjust the linearity. i.e. 0 is obviously 0 but 100psi might be 95psi and it changes the distance of the link radius. thereby changing the leverage and hence the linearity. Simple but effective. Never had to adjust one so far. You have to be careful with the LP ones, a colleague blew in one once and I shouted but to late it was wrecked. Allister

Thanks for the video. I have a cheap pressure gauge attached to a 12VDC air compressor. I have only used it twice and it worked perfectly until today. The compressor air passes through the gauge hose but it stays at zero. I tapped the gauge lightly but it is still locked on zero. Since the gauge is not leaking air I suspect something is jammed possibly an internal gear. I am going to open the gauge see if I can clear the obstruction and lubricate it with a very small amount of silicon lubricant. If it still doesn't work at least I'll know I tried to repair it.

My bicycle floor pump gauge has ceased to operate so I thought I would disassemble to see 'how it works' and 'can I fix it'. It wasn't obvious to me that the copper ring was actually a tube (flattened). I suspect in my case that the brass or copper section is blocked and can't easily be cleaned. Your video explained the 'How it works' excellently. Thanks. Edit... I have since drilled a very small hole (1 mm) in the far end of the flattened copper tube, and blew compressed air in the reverse direction. In this process a small quantity of ‘stuff’ was expelled out of what would normally be the gauge inlet. I then sealed the small hole with solder. Low and behold the gauge then worked. I reassembled and tested ok.
