Landslip Monitoring

After the massive 7.8 magnitude  Kaikoura earthquake in 2016 Harvest Electronics were commissioned to monitor the landslips which had blocked the road and rail network for 50km (30 miles). The cliff faces adjacent to the road and rail were unstable so 50 base monitors and over 100 sensors were deployed to detect pending and actual landslips and rockfalls and send alerts during the three year rebuild to protect the workers  and to prevent any trains from crashing into a new landslip. The wireless tilt (inclinometer) sensors continuously monitor the angle and send instant alerts up to 500m to the base unit if the preset angle delta is exceeded.The displacement sensors use stainless steel draw wire sensors (string pots) to continuously monitor movement to better than 1mm. The sensors can be directly connected to a base unit or be installed up to 2km from the base unit using a Harvest XLR radio.Contact us for more information on our landslip monitoring solutions.
