10 Oct 2006 -- Macro Sensors' 24Vdc-operated LVDT position sensors feature a true zero to 10V output for easy field integration with PLCs, digital indicators, ADCs, computer-based DAQ systems and QC data collection systems. The company explained that true zero voltage output is a valuable feature that permits a user to know exactly when the LVDT's core is positioned at the beginning of its linear range of operation. The 24Vdc operating power is available from virtually any PLC and from most DAQ systems.
Using built-in electronics, the SE 750 series of general purpose DC-LVDTs provide frictionless operation and dynamic response, but with the convenience of DC input and pre-calibrated output. These devices promise highly reliable, contact less operation with high resolution, excellent repeatability and low hysteresis.
Performance specifications and easy field integration of these industry-standard 19mm diameter LVDTs make them suitable for a range of position measurement applications including valve position sensing, hydraulic cylinder positioning and as machine tool positioners and automatic assembly equipment.
The SE 750 series is available in nine standard full scale ranges from 2.5mm to 500mm. Maximum linearity error for sensors is ±0.25 per cent of FSO, with ±0.10 per cent of FSO available as an option. Operating temperature range is -20°C to 70°C. Units operate from 24Vdc nominal, 15Vdc to 24Vdc ±10 per cent, at 30mA nominal input and provide a full-scale output of 0 to 10Vdc over the specified linear sensing range.
These single-ended LVDTs feature a through-bore design that makes the sensor's core accessible from both ends for better mechanical support and core guidance as well as facilitating bore cleaning if needed in an application. Stainless steel housings act as supplemental magnetic shields to reduce the effects of external AC magnetic fields. The LVDTs are optionally available with Teflon bore liners and metric threaded cores. Available from stock, pricing of the SE 750 series of general purpose DC-LVDTs begins at Rs.11,460.08 ($248).
