Questions & Answers : 

• What types of sound level values can the WS302 sensor provide?

The sound level sensor can provide current (SPL), continuous equivalent (Leq) and maximum (Lmax) sound level values, meeting a wide range of sound monitoring and analysis requirements.

• How accurate are the WS302's acoustic measurements?

The WS302 offers measurement accuracy of ± 3 dB over a temperature range of 0°C to +45°C, making it suitable for industrial and commercial use.

• How long does the noise sensor battery last?

The battery can last over 4 years with rapid weighting deactivated and over 1.5 years with rapid weighting activated, ensuring minimal maintenance.

• How does it alert users when thresholds are exceeded? 

The WS302 is equipped with an LED indicator that lights up when thresholds are exceeded, enabling rapid reaction to abnormal sound levels.

• How does the sensor handle A- and C-weighted measurements?

The noise sensor can switch between A and C weightings according to the user's needs, enabling precise measurements to be taken in different noise environments.
