Overview

SUCH industrial-grade noise sensor features a stainless-steel housing for excellent weather resistance and reliability, designed for environmental noise monitoring. It supports multiple communication interfaces, including RS485, 4-20mA, 0-5V, and 0-10V, for easy integration and data transmission. It can measure noise levels from 50 to 130 dBA with an accuracy of ±3 dB, making it suitable for industrial sites, urban environments, and various other noise monitoring scenarios. It also features low power consumption (2W) and a wide voltage input range (DC12-24V).

Feature

Double-nut mounting: Secure installation and easy assembly and disassembly ensure stable and accurate measurements.
Weatherproof: Heat-resistant, cold-resistant, and corrosion-resistant. Built-in reverse polarity protection and RS485 overvoltage protection ensure a stable and reliable structure.
Industrial-grade performance: Low-power chip design ensures long signal transmission distance and stable measurement without drift.

Industrial noise sensor is smooth to mount

Picked up this industrial noise sensor to track ambient decibels near our metal stamping zone for OSHA compliance. The stainless steel housing and included L-bracket made clamping it to the steel beam super straightforward. Readings stay stable without random spikes. The data line gland seal on the back feels tight enough against drifting grinding dust.
