Ashcroft differential pressure transmitters incorporate the TruAccuracy™ specification. Ashcroft’s accuracy claim is based solely on terminal endpoint methodology and not on statistically derived accuracy claims’.
TruAccuracy™ means that Ashcroft differential pressure transmitters include zero offset, non-linearity, hysteresis, non-repeatability, zero offset and span adjustment error in their accuracy statement.
The user thus has a ready-to-install device at his disposal that does not require any initial calibration after installation. This considerably reduces the time and costs involved.
Other commercially available measuring devices usually do not include information on zero point deviation and span error in their accuracy specifications, so that these measurement errors (up to ±1.00%) must be added to the accuracy in order to achieve reliable performance characteristics.
