The high-temperature HATR-750 series of LVDT position sensors from NewTek Sensor Solutions offer a solution to sensors that fail when operating in environments with unanticipated temperature spikes.

For example, steam valves in power generation plants can have undetected leaks when moving, causing periodic rises in temperatures beyond original operating specifications. Sensors not designed for temperature spikes can fail when exposed to briefly elevated temperatures.  When failing sensors are retrofit with a HATR-750 higher temperature LVDT, the problem goes away and operators get an output of valve position.

Hermetically sealed and constructed of 0.75” diameter stainless steel, these AC-operated LVDTs operate in fluctuating temperatures from -54°C to 204°C, (-65°F to 400°F). Windings are potted inside the hermetically-sealed housing with epoxy for added protection against the conditions caused by harsh environments.  Units withstand shock and vibration for a consistent output.

Available in measurement ranges of ±0.05 inch (1.27 millimetres) to ±10 inches (250mm).
