Hello all-
Does anyone know of a decent, adjustable 1/8"NPT pressure gauge to replace the one on our 6000 series Zahm piercer?
I have been buying replacements directly from Z&N. The thing is, I've been going through them like mad; like one every 2-3 months. At $45 a pop, it's getting a bit expensive. The gauges on my series 1000 checker (classic Z&N shaker) last 3 times as long - and are used 5 times as much. It's just the piercer that goes through them.
I made a "TGTimm" testing/calibration rig, and check them often. The failure mode is that they keep sticking and loose any kind of reliability after a few (as compared to the 1000 shaker) uses. (Meaning I calibrate it at, say 10 PSI, but then it doesn't zero out, or it is not in calibration at 5 or 15...) We use it about 10-12 times every two weeks (during mobile canning runs.) The 1000 is used multiple times daily. It's a mystery to me why these things are failing.
I am seriously considering just ditching the Z&N OEM gauge and buying non-adjustable replacements from McMaster Carr at $10.50 each. Considering that the Z&N ones are basically disposable at this point, I can go through 4 of the cheaper ones for the same outlay.
It kills me to do that, though... I love the idea of being able to calibrate these things rather than just chucking them once they go out of adjustment.
Any advice, leads, or other ideas would be greatly appreciated!
