Macro Sensors has introduced a new line of 24V single-ended DC-LVDT position sensors that provide up to 10V output to operate in conjunction with PLCs, digital indicators, A/D converters, computer-based data processors, and QC data collection systems.

Utilizing built-in electronics, the company said the SE 750 Series of general purpose DC-LVDTs provide the desirable features of AC-operated LVDTs, but with the convenience of DC input and output. The high reliability, easy field integration and excellent resolution of these industry-standard 19mm devices make them suitable for a range of position measurement applications including valve position sensing, hydraulic cylinder positioning, and as machine tool positioners and materials testing extensometers, Macro Sensors said.

The company offers the new DC-LVDT line in nine standard ranges from 2.5mm to 500mm. Maximum linearity error for sensors is less than or equal to 0.25 percent of FSO, with 0.10 percent of FSO available as an option. Operating temperature range is -20C to 70C. Units operate from 24V DC nominal, 15- 24V DC 10 percent or 30mA nominal input and provide a full-scale output of up to 10V DC over the sensing range.

As single-ended LVDTs, the devices terminate through a sealed axial connector that prohibits the core from passing completely through the coil assembly. A through-bore design makes the sensors core accessible from both ends for better mechanical support and core guidance, as well as facilitating bore cleaning, Macro Sensors said. Stainless steel housings act as magnetic shields to reduce the effects of external AC magnetic fields. Sealings meet IEC standard IP-62. For added protection against the environment, the devices are optionally available with Teflon bore liners and metric threaded cores. In addition, Macro Sensors can provide a range of mounting accessories, core extension rods and DC power supplies.

Available from stock, pricing of the SE 750 Series of general purpose DC-LVDTs begins at $248.
