AccuSense™
Model ASM
High Accuracy
Pressure Transducer
Setra’s Model ASM is the highest accuracy transducer for
measuring gauge, absolute, compound and vacuum pressure in the AccuSense™ product line. Its ±0.05% FS accuracy
is calibrated using the “End Point Method”, which improves
linearity when compared to competitive transducers which
use the “Best Fit Straight Line Method” of calibration. The
ASM’s calibration is tamper proof by utilizing a SecureCal™
calibration key, which eliminates inadvertent adjustments,
while allowing authorized users to adjust the sensor’s calibration coecients for a true sensor calibration. The design
of the ASM oers class leading overpressure capability and
multiple pressure and electrical ttings for a wide range of
applications.
n Reliable Testing Data
High Accuracy For Demanding Applications
The Model ASM pressure transducer uses a resonant variable
capacitance sensor. This sensor is linearized and thermally
compensated through a computerized curve tting algorithm that optimizes the sensor’s linearity for maximum accuracy in demanding applications.
Robust Design & Construction for Reliable Service
The Model ASM is designed and built to withstand demanding applications. The laser welded sensor construction, designed with a positive overpressure stop, enables the sensor
to resist overpressure conditions up to 10X in all pressure
ranges.
Secure and Fast Calibration & Service
The Model ASM is ideal for the Test & Measurement industry
because it adheres to the stringent accuracy requirements.
In order to make adjustments, the ASM utilizes the SecureCal™ calibration key, providing secure calibration. The SecureCal™ provides the ability to calibrate zero and span coecients through a simple push button and rotary adjustment
dial. The SecureCal™ also oers the option to restore factory
defaults for fail-safe sensor calibration.
