Press Release Summary:
AC-operated CD 375 Series miniature LVDTs employ compact 3/8 in. dia design. Contactless position sensors are available in full-scale measurement ranges from +/-0.025 to +/-2.0 in. and offer core-to-bore radial clearance of 0.012 in. Units feature repeatability with error of less than 0.01% of FSO and maximum linearity error of +/-0.25% FRO. Operational with differential input LVDT signal conditioners, they function in temperatures from -65 to 220 deg F.Original Press Release:
Miniature LVDT Position Sensors Operate in Tight Places Without Sacrificing Performance
Pennsauken, NJ, May 7, 2002. Macro Sensors offers the CD 375 Series of miniature LVDTs for linear position measurement in OEM and end-user applications with tight space restrictions. A compact 3/8" diameter design makes these AC-operated LVDTs suitable as an integral part of devices such as hydraulic actuators, servo valves, medical equipment and other small mechanisms. A lightweight low mass core also make the small contactless position sensors ideal for applications having high dynamic response requirements such as industrial robots, ATMs, copy machines, plastic injection molding machines and automatic inspection equipment.
Available in full-scale measurement ranges from ±0.025" (±0.63mm) to ±2.0" (±50.0mm), the CD 375 Series LVDTs offer a 50% larger core-to-bore radial clearance (0.012") than similar sized competitive units. The units also feature excellent repeatability (error of <0.01 % of FSO), high resolution and the highest sensitivity consistent with good linearity (maximum linearity error of ±0.25% FRO).
Environmentally robust, the CD 375 Series operate in temperature extremes of -65°F to +220°F (-55°C to +105°C). Stainless steel housings and epoxy encapsulation protects units from environmentally hostile conditions. External sealing of the miniature position sensors meets IEC standard IP-61.
In addition to offering the CD 375 LVDTs with optional Teflon® bore liners and metric threaded cores, Macro Sensors can design and produce custom units with higher ambient temperatures and different lead wire exit points and connectors. Units can also be vented for operation in pressurized fluids and constructed of materials resistant to mild nuclear radiation.
Interchangeable with most manufacturer units, the CD 375 Series LVDTs operate with any conventional differential input LVDT signal conditioners. Macro Sensors manufactures a full line of LVDT signal conditioners that offer optimum performance from any CD 375 Series LVDTs.
Pricing for the CD 375 Series LVDTs begin at $101 and go up to $391, depending upon range. Quantity discounts available. For price and delivery information, please contact Eileen Ellis at 856-662-8000/ email: sales@macrosensors.com or visit our web site at www.macrosensors.com.
