Macro Sensors has designed a series of high-temperature and rugged LVDT linear position sensors that can be used in various military and defence applications.

These include fuel/oil-level monitoring, load levelling of artillery platforms and controlling flight surfaces of airplanes and rudder positions of aircraft carriers, tankers, ships and submarines.

Built to withstand 400 temperature spikes, the Hstar 750 Series Hermetically Sealed Position can withstand the harsh environments and high-temperature peaks common in military aircraft and equipment.

As position feedback components for closed-loop servo systems, these LVDT linear position sensors can serve as single or multiple channel devices, depending on redundancy and reliability requirements.

Most perform in quad-channel systems for military aircrafts such as the C-17 to the JSF fighter.

The Hstar 750 Series Hermetically Sealed Sensors can also be used with land vehicles such as tanks and trucks, serving as feedback devices on active suspensions for load levelling, as well as artillery platform levelling.

A combination of these position sensors with hydraulic actuators ensures that a firing platform can be precisely levelled very quickly, even while in motion.

By combining the high-temperature-resistant linear-position sensor with hydraulics and a suitable gyro system to measure roll and yaw, tank canons can ‘shoot on the run’, reducing reaction time.

Hstar LVDT position sensors can also be used to monitor moving surfaces, such as the skew of flaps of a Boeing 777, the exhaust nozzle of an F-14 or the hydraulic reservoir of an F-22.

The LVDTs are also used to monitor the position of the Thrust Reverser vanes of the 787.

Macro Sensors offers several standard options for Hstar 750 units, including metric threaded cores, smaller diameters and low-mass cores.

On special order, the Hstar 750 sensors can be constructed for immersion in pressurised fluids and exposure to radiation at 3×107 Rads for 40 years.

These 3/4in (19mm) diameter AC-operated linear position sensors are available in ranges of +/-0.050in (+/-1.25mm) to +/-10in (+/-250mm)
