Model ASL Low Differential Pressure Transducer
Brand: Setra Systems, IncSetra’s Model ASL is the highest accuracy transducer for measuring low differential pressure in the AccuSense product line.
Its ±0.07% of Full Scale 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 ASL'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 coefficients for a true sensor calibration.
The design of the ASL offers class leading overpressure capability and multiple pressure and electrical fittings to accommodate a wide range of applications.
