| | Jan 18, 2010 — Macro Sensors (www.macrosensors.com), US-based manufacturer of LVDT Linear Position Sensors and Rotary Position Sensors and Transducers, is serving the petroleum industry with LVDT-based linear position sensors that are used for position feedback control of down hole drilling equipment such as bore scopes that measure the ID of the drilled hole.
The LVDT linear position sensors for down hole applications are custom built to survive high temperatures and high pressure. Units are rated for pressures to 20,000 psi, in electrically non-conductive, chemically benign media, at continuous temperatures as high as 400 degrees F. The high temperature ratings are achieved by using special construction materials for the linear position sensors that include special high melting point soldering. To accommodate high pressures, the sensor case is vented to equalize pressure inside and outside of the LVDT linear position sensor.
Offering a compact 3/8” diameter design, these AC-operated LVDT linear position sensors serve well as an integral part of devices with tight space restrictions. A lightweight low mass core also makes the small, contactless linear position sensors ideal for applications having high dynamic response requirements. Units operate with any conventional differential input LVDT signal conditioners to provide position feedback back to operators at the surface.
