683S04 High-Temperature Charge Output Uniaxial Accelerometers

The 683S04 is a premium-engineered, high-temperature uniaxial accelerometer designed specifically for capturing critical structural dynamics and transient events in intense physical and thermal testing fields.

Operating on a specialized piezoelectric charge mode configuration, this sensor offers a 20 pC/g nominal sensitivity, a dynamic measurement threshold of ±1000 g, and a linear high-frequency bandwidth tracking flawlessly up to 11 kHz inside a rigid Titanium/Stainless Steel housing.

Engineered to function as a drop-in 1:1 direct replacement and physical equivalent for industry standard legacy PCB Piezotronics models, it provides acoustic specialists and NVH engineers with identical form factor performance with the benefit of shorter B2B supply chain lead times.

Why the 683S04 Stands Out?

• Extreme Temperature Resistance: Operates from -50°C to 260°C with ultra-low drift (0.020%/°C).
• High Sensitivity & Precision: 20 pC/g output for detecting minute vibrations.
• Wide Measurement Range: ±1000g range for versatile industrial applications.
• Anti-Interference Design: Differential signal output reduces noise in high-EMI environments.
• Rugged Construction: IP68 laser-welded housing ensures dust/water resistance.
