Setra AccuSense ASM Specifications

AccuSense™ Model ASM

High Accuracy Pressure Transducer

AccuSense™ Model ASM with

SecureCal™ Accessory

DESCRIPTION

The AccuSense™ Model ASM is a high performance pressure transducer designed for industrial applications requiring high accuracy. The all stainless steel construction, groove design, and hydrophobic porous plug protect the recessed air vent from contaminents in industrial environments. The patented resonant variable capacitance sensor is laser welded, providing high accuracy and stability.

TEST & MEASUREMENT

FEATURES

High Accuracy: ±0.05% FS (End-Point)

Low Thermal Error Over Wide Temperature Compact Design (1.3” Diameter) Optional Overpressure Protection up to 10x

Proof Pressure Low Thermal Error Secure & Simple Field Calibration Rugged Stainless Steel Construction Multiple Congurations Available CE Mark & EU RoHS Compliant

APPLICATIONS

Engine Test Stands

Particle Test & Analysis Industrial (High Accuracy) Dynamometers Research & Development Refrigeration Testing

The electronics platform enables outstanding performance over environmental temperature ranges.

As part of the AccuSense™ product family, Model ASM’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.
