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 coefficients for a true sensor calibration. The design of the ASM offers class-leading overpressure capability and multiple pressure and electrical fittings for a wide range of applications.
High Accuracy for Demanding Applications – The Model ASM differential pressure transducer uses a resonant variable capacitance sensor. This sensor is linearized and thermally compensated through a computerized curve fitting 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 Secure-Cal™ calibration key, providing secure calibration. The SecureCal™ provides the ability to calibrate zero and span coefficients through a simple push button and rotary adjustment dial. The SecureCal™ also offers the option to restore factory defaults for fail-safe sensor calibration.
