Standard


(Adjust the range based on the standard zero points, stainless steel 316L diaphragm, filling fluid is silicone oil)


1:Performance specifications

Adjust the reference accuracy of the range

(Including linearity, hysteresis, and repeatability from zero)

± 0.075%

If TF>10 (TF=Maximum range/adjustment range) then:

±(0.0075×TF)%

The square root output accuracy is 1.5 times the above linear reference accuracy

Optional highest accuracy 0.05%.
