Reference accuracy (including linearity, backfall, repeatability from zero)
±0.05% ±0.075% ±0.1%
If TD>10 (TD = maximum volume/adjustable range), it is:
±（0.005*TD)% ±（0.0075*TD)% ±（0.01*TD)%
Ambient temperature influences
The total influence at (-25~ 65)°C is:
±（0.15*TD 0.05）%*Span
The total influence at (-40~-25)°C and (65~85)°C is:
±（0.2*TD 0.05)%*Span
Overvoltage effects
±0.075%*Span
Long-term stability
±0.1%*Span/3 years
Power Impact
0.001%/10V(12~36)VDC, negligible
Range limit
Within the upper and lower limits of the range, it can be adjusted arbitrarily
It is recommended to choose a volume code with the lowest possible volume ratio to optimize performance characteristics
Zero setting
Scaling range≥ minimum range
Installation location impact
Changes in the mounting position parallel to the diaphragm surface do not cause a zero-point effect.
If the mounting position is not parallel to the diaphragm surface, it can be eliminated by calibration. Countermeasure
There is no impact
Insulation resistance
100MΩ or more to ground (DC500V)
Dielectric strength
Ground AC500V50/60Hz, 1 minute
Response time
The damping constant of the amplifier component is 0.1S, and the sensor time constant is:
(0.1~1.6)S, depending on the range and the ratio of the range. Additional adjustable time
The constant is: (0.1~60)S. For non-linear outputs (e.g. square root function)
The impact depends on the feature and can be calculated accordingly
Ambient temperature: -40~ 85°C-20~ 65°C (with display)
