The Model 708 Wireless Acoustic Transmitter is a battery-powered device designed to measure vibrations and temperature and to transmit this data, via a wireless network, back to a gateway device. The transmitter contains three printed circuit boards consisting of the feature board, the sensor board and the power module interconnect board all housed within a plastic enclosure. A piezo-electric element is mechanically connected to a stainless steel waveguide fitted to the bottom of the enclosure. Power is provided by a Model 701PG SmartPower Green Power Module, covered by IECEx BAS 11.0026X. The battery is located in a separate compartment and access is gained by a small threaded cover. This battery may be replaced within the hazardous area.
