AP Sensing Replaces Competitor’s DTS in Meir Traffic Tunnel Stoke-on-Trent, UK When a competitor’s LHD (Linear Heat Device) could no longer be maintained locally or checked for correct operation, it was decided to replace it with an AP Sensing DTS (Distributed Temperature Sensing) device in the 284m long Meir tunnel. The busy traffic tunnel is located in a heavily trafficked area in Stoke-on-Trent in England. It was necessary to maintain the critical safety systems within the tunnel and therefore to provide a reliable and cost-effective DTS solution. Working together with our regional partner, one of the challenges was to replace the DTS but to ensure proper operation using the various sensor cables that were previously installed.
