Readouts
Intrinsically Safe Readout
The Model 404 Intrinsically Safe Vibrating Wire Readout is a portable, low-power, hand-held unit, designed in cooperation with GEL Instrumentation, that is capable of running for more than 6 hours continuously on a single charge. The Model 404 is designed to read specific GEOKON vibrating wire sensors in hazardous environments (IECEx ia, approval SIM 13.0014X) and is approved only for designated GEOKON sensors, identified as Type 1, Type 2, Type 3 and Type 4. The Model 404 is based on the GEOKON Model GK-404 Readout and provides 6 excitation positions (A-F) with a display resolution of 0.1 digit. Special versions of the Model 4151 are available with extended ranges.
These gauges are particularly useful for measurements in high strain regimes such as on plastic pipes or piles and on fiberglass structural members and rebars. A unique design allows these gauges to be manufactured without increasing their overall length, making them particularly suitable where space and or access is limited.
