Industrial grade long stem stainless steel noise sensor decibel meter for industry.

1. With a detection frequency of 20 Hz to 12.5 kHz, this high-acceleration noise sensor offers a wide detection range and a stable signal. 2. Its industrial digital sensing technology utilizes a digital signal processing chip with good linearity and a wide dynamic range. 3. It is waterproof and dustproof for long-term durability. It employs a high-sensitivity condenser microphone and features a wide measurement range. 4. It supports an operating temperature of -20°C to +60°C and 0% to 80% RH, with a measurement range of 30 dB to 120 dB. 5. The 10-30V wide-voltage power input can be wired for 485 signals; be careful not to reverse the two wires. Specification: Item Type: Noise Sensor.
