The miniature AC-operated LVDT position sensors from Macro Sensors feature high pressure and temperature configurations to enable performance in harsh environments. Vented versions of the CD 375 series of miniature LVDT’s are also available for operation in pressurised fluids.
The sensors offer a lightweight, low mass core and a compact 3/8in diameter, and suit high response dynamic measurement such as valve position and pneumatic cylinder positioning, as well as serving as integral parts of small mechanisms which require units to withstand high pressure and high temperature.
These operate within a temperature range of -55°C to +200°C and operating pressures of 35kpsi. The sensor case is vented to equalize pressure inside and outside the LVDT linear position sensor.
The sensors are available in full-scale measurement ranges from ±0.025in (±0.63mm) to ±1.0in (±25.0mm). They are also customisable with Teflon bore liners, metric threaded cores, and lead wire exit points
