  Low cost sound or noise measurement for PLCs and control systems

Useful in security systems, remote monitoring, detecting mechanical failures or malfunction.

  Comes with two mounting nuts
  +/- 4% accuracy*
  Reverse polarity protected

* Sound measurement is significantly influenced by sensor orientation and distance from the sound source (higher frequencies attenuate more rapidly over distance than lower frequencies). In addition, non-sinusoidal sound sources may vary in their sound energy component.

Design considerations

The SS1, SS2, and SS3 are a low cost way to input sound or noise information into a PLC, process control meter, distributed control system (DCS), or other industrial control system. The SS1-420 can be mounted through any 1/2" hole and the two wires connected to an analog input card or other two wire 4-20 mA current loop circuit.

The sound aperture should be mounted to prevent rain, snow, or ice damaging or attenuating the sound signal.

The SS1, SS2, and SS3 are designed for low cost applications where standard accuracy is acceptable.

Because the SS1 has a PVC housing,  care should be taken to insure that the operating environment does not get so hot that the PVC housing will soften. This may happen at temperatures around 180 to 190 degrees F.

The sound sensors should not be used as the sole sensing element in critical equipment or safety applications.
