PCE Instruments PCE-FST-100-2010-NMS Audio sensor Voltage: 30 V DC 1 pc(s)

The sound sensor is Ideal for all applications, in which ambient noise or noise level must be monitored precisely. Whether in city noise measurement stations, factory halls, schools or in research projects – this sound sensor provides reliable measurements to meet safety requirements and comfort requirements. The sensor covers a measuring range of 30 ... 120 dBA and operates in the frequency range of 20 ... 12500 Hz The resolution is typically 1 dB, WAS is sufficient for most practical applications, while the accuracy is ±2% of the measuring range plus ±0.5 dB, based on the reference tone of 94 dB at 1 kHz. The sound sensor provides a precise and reliable basis for all acoustic measurements.

Specific technical features include a digital interface via RS‑485 with Modbus RTU, which enables easy integration into existing systems. The sensor uses a high-quality condenser microphone with A-rating, which takes human hearing into account. The response time is at most 2 seconds. The sound sensor is suitable for wall mounting and has a weather-proof housing, which is also designed for outdoor use. The device is particularly useful for companies, authorities or research institutions that need a continuous monitoring of noise sources, for example, in production sites, during traffic control or in urban noise projects.
