Consult factory for custom calibration ranges and other temperature compensation ranges

Ashcroft’s TruAccuracy™ specification is exclusively based on terminal

point methodology instead of statistically derived schemes like

‘best fit straight line’.

TruAccuracy™ means the Ashcroft AXLdp has ±1.00% of span

accuracy out of the box. Zero and span setting errors are already

included in the ±1.00% of span accuracy spec. 

The AXLdp is ready to be installed with no additional calibration

adjustments required.

A unit from another manufacturer advertised as ±1.00% best fit

straight line may actually be a ±2.00% to ±3.00% device. Using best

fit straight line method, the accuracy spec does not include zero and

span setting errors, which can be as much as ±1.00% each.

What Does It Mean?

Featuring a highly reliable variable capacitance sensor using the

patented Ashcroft® Si-Glas™ sensor. This ultra-thin single crystal

diaphragm provides inherent sensor repeatability and stability.

Ashcroft® Si-Glas™ Sensor Technology

Sensor Cross Section

The silicon diaphragm sensor has no glues or

other organics to contribute to drift or mechanical

degradation over time.
