Macro Sensor LVDT Position SensorMacro Sensors’ miniature AC-Operated LVDT Position Sensors in high-pressure and -temperature configurations are designed to perform in harsh environments. Vented versions of the CD 375 Series of Miniature LVDTs are also available for operation in pressurized fluids. Offering a lightweight, low-mass core and a compact 3/8-inch diameter, these sensors are a good fit for 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. – macrosensors.com
