TT-DA Duct Averaging Sensors

The TT-DA temperature sensors are used for measuring temperature in ducts where an average reading across the air flow is required. Units contain either high quality thermistor, nickel or platinum sensing elements which are housed in a ‘Nylon 12’ tube, spaced at 0.5 m intervals along the standard 2.2 m length.
The -CVO active output option combines 4 pre-set ranges and selectable output mode, customised output range scaling enabling a choice of
outputs and ranges on one unit.

The TT-DA's sensing elements are strategically placed along a nylon tube, providing an accurate average temperature reading across the entire length of the duct. It is possible to choose from various types of sensing elements and customise the number of sensors, with specific distances between them, to make the product adaptable to all requirements. This data can be easily integrated into building management systems (BMS), enabling real-time analysis and control. By investing in the TT-DA range, data centre managers can significantly improve the efficiency, reliability and overall performance of their facility.With its exceptional accuracy, flexibility and durability, the TT-DA is the ideal solution for maintaining optimal temperature conditions and safeguarding the equipment in your data centres.
