Modular releases industrial sensors for AAFP
November 2012
Sensors & Transducers
Modular’s new advanced acoustic field processor (AAFP) is compatible to piezoelectric noise and vibration sensors as well as microphonic sensor cables. Traditionally, the application of the AcoustAlert field processor was well established in security perimeter detection applications using cables with microphonic characteristics.
Modular has now released two new detection sensors for the AAFP, Diskflex and Bridgeflex, which can be fitted onto fixed objects (motors and machinery) to monitor vibration, noise or seismic impacts. The Bridgeflex sensors are currently being tested on big electric motors used in industrial manufacturing and service industries. Bridgeflex connected to the AcoustAlert field processor can monitor the acoustic changes of these motors when they are under normal, over and under load conditions, and generate an alarm depending on user determined criteria. Diskflex, working on the same piezoelectric principals, can be deployed in a clean controlled environment to monitor object movements, vibrations and noises within the audio band.
The AcoustAlert field processors communication over a conventional TCP/IP LAN environment makes connecting and networking multiple field processors as simple as connecting a number of PCs on a computer network – each AcoustAlert field processor has its own IP address. The application of Modular’s AcoustAlert field processor and sensor devices is further enhanced by software applications that manipulate the data to achieve the desired result. Data is written to an SQL database and from there can be monitored and displayed in GUI formats according to client requirements. What makes this field processor unique is the intelligence of design based on user defined acoustic DSP concepts that can be burnt into the field processor to make it a signal analyser for the application at hand. Each AcoustAlert processor has two high impedance acoustic input channels and two line level audio output channels. The unit is powered from a 12 VDC supply. The technology has application wherever acoustics can be used to manage and control machine processes.
