VW Readout
The model HRVW handheld vibrating wire readout is a portable vibrating wire sensor data acquisition instrument for manual detection. It is designed for the readout of all single coil vibrating wire sensors, such as vibrating wire strain gauges, steel bar gauges, piezometers/pore water pressure gauges, crack gauges/crack gauges, axial force gauges, anchor cable gauges,and earth pressure gauges etc,.The readout also displays the temperature of the transducer (embedded thermistor/DS18B20) with a resolution of 0.1°C.
Overview
HVLog -s/f handheld vibrating wire readout is a vibrating wire sensor data acquisition instrument for manual detection. It is suitable for frequency signal acquisition and temperature signal acquisition of various single coil vibrating wire sensors, such as vibrating wire strain gauges. , steel bar meter, piezometer, crack meter, axial force meter, anchor cable meter, earth pressure box and other vibrating wire sensors.
The readout uses a 32-bit ARM.Cortex processor, which can realize real-time data collection of vibrating wire sensors, signal processing, display, data storage, transmission, historical data query and other functions. The datalogger hardware has a high degree of integration and strong anti-interference ability. It adopts advanced digital signal processing technology and has high measurement accuracy. The datalogger has a built-in rechargeable lithium battery, which is economical and environmentally friendly. The acquisition instrument has stable performance, high testing accuracy, wide temperature range and easy operation. The data storage adopts U disk mode, which increases the storage capacity and makes data operation more convenient.
Characteristic：
- 0.05Hz frequency measurement accuracy
- Add a power frequency trap to make the signal more resistant to interference.
- 4.3-inch display screen, which can display signal frequency value and signal amplitude value at the same time, convenient for sensor fault diagnosis
