biaxial tiltmeter

A biaxial tiltmeter measures angular displacement in two orthogonal planes at once. On a retaining wall, for instance, it can track both the leaning angle and the lateral twist as backfill pressure changes. Kingmach builds these sensors around MEMS accelerometer cores with on-board temperature compensation. That matters because thermal drift in unheated instruments can mask true ground movement over a cold night or a hot afternoon. The housing is a welded stainless steel cylinder rated for submersion, and the cable entry uses a dual-seal gland. Inside, the signal conditioning board buffers the raw analog signals and feeds a microcontroller that outputs digital readings over RS485 or a current loop. We don't publish a one-size-fits-all accuracy spec because the final performance depends heavily on installation. A properly grouted bracket on a dam buttress will give significantly better long-term stability than a shallow stake in loose soil. That said, users typically see repeatability within a few arc-seconds on stiff concrete. Kingmach has deployed these devices in landslide early-warning networks across Southeast Asia and in structural health monitoring programs for highway bridges in Latin America. Our engineering team reviews the measurement range and resolution with you before quoting, so the sensor matches the expected deformation rate. We also stock common spare parts in regional warehouses, and we provide remote support for troubleshooting noise, zero shifts, or data dropouts. If you need a large volume of units for a tunnel monitoring project, we can batch-test them for interchangeability and supply a calibration table with each shipment.
