Description

Dirancang untuk digunakan, dipindahkan, dan digunakan kembali secepat mungkin, SAAScan ideal untuk aplikasi yang mengharuskan pengukuran bentuk lubang bor berulang kali—misalnya, jet grouting dan pengeboran lubang bor. Konstruksi SAAScan yang kokoh dan tahan lama menggabungkan sambungan tahan puntir dan segmen baja tahan karat berdinding tebal. Konstruksi ini berisi rangkaian sensor gravitasi MEMS yang ringkas.

SAAScan menghemat waktu dan biaya. Sistem ini berbasis gulungan yang memungkinkan pengukuran ratusan lubang. Selang ekstensi dan terminator kabel yang unik memungkinkan SAAScan tetap terpasang pada gulungan sementara sisa panjang rangkaian dipasang untuk mengumpulkan data waktu nyata yang akurat.

Panjang segmen SAAScan adalah 500 mm. SAAScan dapat diproduksi dengan panjang standar hingga 50 m. Hubungi Measurand untuk menanyakan tentang panjang khusus. Semua ShapeArrays™ diproduksi di fasilitas bersertifikat ISO 9001.

Measured at 20°C, with X-Mark facing a consistent direction.
Long term measurement value based on field measurements of vertical arrays > 1 year of operation.
Short-term measurement ≤ 24 h.
Value based on Average in Array (AIA) setting of 1000 samples.
Specification is for 3D mode within ± 15° of vertical. Vertical accuracy degrades with angular deviation from the vertical.
Sample size for segment precision is 540,000 readings. Data was collected for 3 different positions within +/- 10° of the X, Y, and Z axes. Figures provided fall within 99.7% confidence interval (3-sigma value).
24 h stability is the maximum change in the sensor readings in a 24 h period for an instrument installed in repeatability conditions. Sample size is 7,200 samples for each 24 h period reviewed. * Caution: Long SAAScans are heavy and winches would be involved in installing them.
