Noise Sensor, Ceiling Mounted, 4-20mA/0-5V/RS485

Ceiling-mounted noise sensor is a high-precision sound measurement device with a measurement range of 30–130 dB, a resolution of 0.1 dB, and a frequency response range of 20 Hz to 12.5 kHz. SUCH noise sensor uses a high-sensitivity condenser microphone, ensuring stable signal, high accuracy, and a response time of ≤3 seconds. It operates in ambient temperatures of -20℃ to +60℃ and humidity levels of 0%RH to 80%RH. Noise detection sensor features a wide measurement range, good linearity, and easy installation, and supports multiple output methods including 4-20mA, 0-10V, 0-5V, and RS485. It is widely used for noise monitoring in homes, offices, workshops, automobiles, and industrial environments.

Feature

• Equipped with a high-sensitivity capacitive microphone for stable signals, precise measurement, and excellent linearity.
• Supports multiple analog and digital output interfaces, suitable for home, office, and industrial environments.
• Ceiling-mounted design for an attractive appearance and convenient installation and maintenance.
