Product Details

135613‑02 is a high temperature LVDT casing expansion transducer for steam turbine TSI monitoring system. It measures the absolute thermal expansion displacement of turbine casing during unit start‑up,shutdown and normal operation.

This HTLVDT sensor converts mechanical casing expansion displacement into standard 0‑5 VDC analog signal. It works with 3500 series differential expansion monitor module to complete casing expansion data collection and alarm judgement. The stainless‑steel enclosure adapts to harsh field environment of turbine workshop.

It is widely applied in steam turbine casing expansion measurement for power plant units. Please match correct measuring range during installation.

Note: This is legacy TSI field sensor spare component,widely used for replacement of turbine monitoring & protection systems.
