Setra AccuSense ASL Specifications

AccuSense™ Model ASL

High Accuracy Dierential Pressure Transducer

AccuSense™ Model ASL with SecureCal™ Calibration Key

DESCRIPTION

The AccuSense™ Model ASL is a high performance pressure transducer designed for low dierential pressure measurements of air or other clean gases. Setra’s variable capacitance technology is industry tested and preferred in applications that demand reliability, repeatability and accuracy.

Model ASL’s exceptional linearity and thermal compensation is achieved through computerized factory calibration and curve tting algorithm. The sensor’s rugged construction and factory conditioning enable high overpressure capability and stability to ensure a highly robust and reliable measurement.

As part of AccuSense™ product family, Model ASL’s zero and span settings are securely set through use of SecureCal accessory making for secure and stable calibration settings. Excellent stability, and secure calibration makes it ideal for high performance industrial, laboratory, and test cell applications.
