The High-Temperature HATR-750 Series of LVDT Position Sensors from NewTek Sensor Solutions offers a reliable and long-term 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 even 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 a reliable output of valve position.

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


Suitable for applications such as machine components, workpiece or valve position sensing in factory automation, assembly, and power generation plants with corrosive environments

Available in measurement ranges of ±0.05 inch (1.27mm) to ±10 inches (250mm), the HATR-750 Series Sensors are ideal for a range of industrial applications such as machine components, workpiece or valve position sensing in factory automation, assembly and power generation plants with corrosive environments. An electrical connection made through a radially-mounted connector reduces housing length so units can fit into tight spaces.

Without internal electronics, the HATR-750 LVDTs can operate in extreme environments unlike many sensors with internal circuitry. The NewTek NTC-6000 Qwik-Cal™ LVDT Signal Conditioner provides the excitation to the position sensor and converts position measurement into digital output for use by computers, PLCs, and data acquisition systems.
