QSY8901 series Vibrating Wire Earth Pressure Cell
Manufacturer:QSY
 
|
Vibrating wire earth pressure sensor is acceptable for long-term observation of contact pressure and foundation pressure which matches asphalt chamber. QSY8901 series Vibrating wire earth pressure cells are devided into double-film cell and single-film cell. QSY8901-2 single-film earth pressure cell is mainly adopted to measure uniformly distributed pressure of soft soil in narrow space. |

QSY8905 series Vibrating Wire Surface Strain Gauge
Manufacturer:QSY
|
Based on the principle of vibrating wire measuring stress, QSY8905 series vibrating wire surface strain gauge works on the surface of structures such as bridge, tunnel, steel pipe, etc. there is a steel wire between two blooms which are welded on the surface of steel structure which is detected. Surface stress moves the blooms, thus changes tensile force of the wire. |

QSY8910 series Frequency-Modulation Earth Pressure Cells
Manufacturer:QSY
|
Based on inductance sensors and the principle of L-C oscillation, QSY8910 series frequency-modulation earth pressure cells transfer physical signals of pressure, replacement, level and weight into electric signals of frequency change. With characteristics of excellent SNR, anti-interference, sensitivity, linearity, repeatability and tiny retardation, the cells is easy to measure and process datum without A/D conversion with help of micro-computer. |
