ZE:908 Acoustic Interface with AC, DC & 4-20mA Current Loop Outputs
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 preamplifer 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) allow 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.
