AVA 08 Frequency Transducer to Q Link Interface 22 Apr 2015 Page 1 of 9 1 INTRODUCTION Quartz pressure temperature transducers are widely used in the oil industry for measuring downhole pressure and temperature with very high accuracy Quartzdyne www quartzdyne com is the leading manufacturer of quartz transducers of which there are two types traditional Frequency Output Transducers sometimes referred to as analog and the more recent Digital Transducers which are accessed via an interface Quartzdyne manufactures a device called Q Link which reads pressure and temperature values of up to 4 digital transducers The data can be displayed on a using Quartzdyne s QConsole software Q Link only supports digital transducers with IPC interface Frequency output transducers are not directly supported by Q Link The AVA 08 Frequency Transducer to Q Link Interface fills this gap It connects between a Q Link device and up to 4 frequency output transducers It measures pressure and temperature frequencies and makes them available to Q Link via C The AVA 08 appears to Q Link as a set of digital transducers Q Link only provides a 3V transducer supply The AVA 08 therefore includes step up circuitry that generates a 5V supply so that any frequency output transducer can be connected including legacy types that would not work below SV Figure 1 AVA 08 and Q Link side by side Avanti Elektronik Limited 44 01224 583132
