Differential pressure gauge replacement
Thread Content
The diaphragm of a differential pressure gauge of type EJA110A on site is damaged (with a range of 0-5 kPa), and no suitable new gauge can be found. Is it possible to replace it with an EJA110E gauge (with a range of 0-100 kPa)?
If it can be adjusted to 0–5 kPa, it can then be replaced.
I was wondering if it’s possible to use 475 to directly change the range on the gauge to 0-5 kPa First replacement
Try it and you'll see....
It can be changed. . . If you want uncertainty, go ahead and mess things up however you like. . . Keep going, keep going. :lol. .
There is no model EJA110E; it should be the EJA110A-E -M, with a range of 0-100 kPa. The one that is broken is the EJA110A-E-L, with a range of 0-10 kPa. The minimum operating range for the EJA110A-E -M is 0-1 kPa, but the client needs a range of 0-5 kPa, which is still feasible – the range can be adjusted using the manual controller.
It depends on his 20% ratio; if it’s 100 to 1, then it’s fine, but if it’s 10 to 1, then nothing can be changed
It’s possible to adjust the range; it’s best to have it calibrated at the metrology laboratory
The pressure difference is relatively small; after installation, it is necessary to perform a zero-point calibration with air
Well, it can definitely be changed. Checked the parameters: faulty gauge EJA110A-A-L, range 0-10 kPa, accuracy 0.075% ； Replacement table EJA110A-E -M, 0-100kpa, accuracy 0.055%. When measuring 0-5 kPa, change the range to 0-10 kPa; the accuracy remains at 0.055%.
