| 424129 | 2006-01-25 01:30:00 | Hi Team One of my clients wants to get the load cells (4) on a 5000 litre tank calibrated. While I think that expectations of the accuracy possible may be a little over-optimistic (±500 millilitres) nevertheless, the calibration must be done. I am looking for a company in the Auckland region if possible. Any ideas? Cheers Billy 8-{) |

| 424130 | 2006-01-25 01:58:00 | How about? (www . airnewzealand . co . nz/aboutus/engineering/calibration . htm) "load cell calibration" (NZ sites box ticked) to Google . ;) |

| 424131 | 2006-01-25 02:20:00 | Or, Australian Calibration Services http://www.auscal.com.au/ They used to have guys based in NZ, Dave Bridgeman ex DSIR was one, but he must be retired now :), in fact force and load cell calibration was their bread and butter work in this country. Edit: look under IANZ Calibration and you will find an Auckland address for their representative. |

| 424132 | 2006-01-25 02:29:00 | It looks as if 0.1% of full scale is typical for load cells. "Only" another factor of 10 wanted. I suspect some reality therapy is needed. | Graham L (2) | ||

It is indeed Graham, also when the cost of calibration with certificate is known, it will be another story :) from ACS: "FORCE MEASURING DEVICES Least uncertainty Force measuring devices, alone or as part of a testing ± 0.25% system in accordance with EN ISO 7500-1:1999, and AS 2193:1978 grade A for forces from 0.01N to 10 000kN in compression and 0.01N to 3000kN in tension" |

| 424134 | 2006-01-25 03:37:00 | Thanks guys . I had already done the research and was looking for any personal knowledge/recommendations . I have now found a good lead via Precision Transducers, and if I am not wrong, this company is another Kiwi success story . I first met up with them as a struggling start-up about 20 years ago and now they are an international force in their field . They pointed me to one of their trusted calibration agents and we'll go from there . I will let the calibration guy deliver the reality check on the resolution attainable . :D Cheers Billy 8-{) |

| 424135 | 2006-01-25 03:44:00 | NIST (used to be the NBS) in the US do some work for foreigners. Looks as if the calibration charge for a force sensor (up to 25000 lbf) would be $US2560. (plus you'd have to get the thing to them, and back). They've got great automated testers, computer controlled with PC-XTs. :) The million lbf machine has hydraulic jacks in the attic to shift the weights. That's a very interesting site. [ NIST (www.nist.gov/). There are lots of books and papers downloadable. They do a lot of research on a lot of subjects. |
