75S2DC Series DC/DC

0.750″ (19.05 mm) diameter, +24 VDC In, 1-10 VDC Out

The 75S2DC Series of 24V DC-operated LVDT’s are ideal position sensors for industrial automation and process applications. Available in measurement ranges of from 0.10″ to 20.0″ the 75S2DC series units offer a wide selection of units for industrial measurements. Often, the 75S2DC LVDT’s can be powered directly from PLC’s containing 24V DC power supplies. The PLC will accept the LVDT’s output directly, thus eliminating the need for any additional equipment for operation.

These units provide a +1 to +10V DC output suitable for use with PLC’s, data collection systems, readouts and other control devices. Additionally, the non-zero based output provides the user with fault detection capability. Most PLC’s have comparator functions capable of providing an alarm indication should the LVDT output ever drop to 0 Volts, indicating a system or LVDT malfunction.

Overall, the 75S2DC series LVDT’s represent an ideal method of providing measurement functions for SPC data collection and process control functions.
