The ZE:908 Acoustic Interface
The ZE:908 is a small and lightweight power supply and acoustic conditioning unit for the Cirrus MV:200 microphone preamplifiers and MK:170 Outdoor microphone units.
Many industrial plants have a variety of process sensors strategically placed around their site so that safety, environmental impact, and efficiency can be monitored and managed, in real-time, from one or more control rooms.
The ZE:908 is also ideal for use as a frontend for data logging and analysis systems where a simple and accurate acoustic input is required and as an interface between an acoustic transducer and a process monitoring system
A range of input and output options
The Cirrus Research MV:200F preamplifier can be used with either a Class 1 MK:224 or Class 2 MK:216 microphone capsule as an input to the ZE:908 via a microphone extension cable with up to 50m of cable supported
The ZE:908 can also be used with the MK:170 Weatherproof Outdoor microphone (when used with the ZL:174 adaptor cable) allowing external noise levels to be measured and recorded.
To allow the ZE:908 to be used in a range of applications, a number of different output types are available. The BNC connector on the rear panel provides one of the following output signal types:
- Amplified A-weighted AC output
- Amplified Z-weighted AC output
- DC Voltage proportional to SPL A weighted SLOW response
- DC Voltage proportional to SPL A weighted FAST response
- DC Voltage proportional to SPL Z weighted SLOW response
- DC Voltage proportional to SPL Z weighted FAST response
The rear panel 15-way D-type connector also provides the option of a 4-20mA current loop output which can be used with standard interface modules.
