LVDT/RVDT signal conditioner LDM-1000

LDM-1000 is a conditioning module for Industrial applications requiring the DIN standard rail mount, form factor.

The LDM-100 LVDT / RVDT conditioner provides everything you will need for interfacing AC powered linear and rotary differential transformers, to your industrial position control system.

The LDM-1000 is designed with maximum sensor / system compatibility in mind. A wide range combination of gains, drive voltages and oscillator frequencies insure compatibility with virtually all LVDT and RVDT type sensors. The LDM-1000 provides several different input / output options, to accommodate varying PLC analog I/O requirements.

Single-ended voltage outputs are possible, with the use of 100% zero suppression, to maximize the sensor stroke utilization while simplifying programming, (no need to deal with sign). Bipolar voltage output will maximize A/D bit usage, with most PLC analog input modules, for applications requiring highest resolution.

The 4-20 mA current output is most useful for applications requiring long signal runs to the PLC, where noise immunity may be an issue. The 4-20 loop is driven by an internal loop supply, provided by the LDM-1000.
