CTU

Combined termination unit

The CTU is the latest development within the Tunnel Sensors product range, designed to provide a robust yet versatile solution for local instrument connections.

CTU

The CTU is a rugged, wall mounted termination unit designed for installation alongside compatible Tunnel Sensors instruments. Due to the diverse tunnel power and communication requirements, the CTU adopts a modular design philosophy. Enclosures and terminal packs are offered separately so customers can specify and purchase the precise configuration required for their application.

The CTU is available with and without an onboard power supply along with a range of terminal packs including sacrificial OVP terminals. Enclosures are manufactured from stainless steel which provide IP67 rated ingress protection. Enclosure lids benefit from quick release catches and a security lock screw to prevent unintended access.
