Frequency to Analog Converter (VW) - Model 8020-59

The Model 8020-59 Vibrating Wire (VW) to Analog Converter provides a simple way to connect Geokon’s vibrating wire transducers to data acquisition systems, which are not capable of reading frequency signals nor able to generate the proper signals required to excite VW transducers. The converter can operate with single transducers, as a stand-alone device, or with multiple transducers in conjunction with the Model 8032 Multiplexer. The converter is powered using either a 12 V or 24 V supply.

Power Requirements: 12 V or 24 V
90 mA @ 12 V (operation), 10 µA (standby)
75 mA @ 24 V (operation), 16.5 mA (standby)
Operation Modes: Single Channel, 16 VW sensors with thermistors, or 32 VW sensors
Output (Analog): 0-5 V, 4-20 mA (non-isolated loop generator)
Resolution: 16 bit
Accuracy: ±0.1% F.S. (0-5 V), ±0.5% F.S. (4-20 mA)
Temperature Range: −20°C to +80°C
L × W × H: 111 × 108 × 36 mm (with cover)
