Page 3: Introduction
LVDT/RVDT Signal Conditioning Module 1. Introduction The LDM-1000 is an extremely versatile LVDT/RVDT (Linear or Rotary Variable Differential Transformer) signal conditioning module. The module supplies an AC sine wave excitation to the LVDT or RVDT, and demodulates, filters, and amplifies the output. -
Page 4: Product Description
An internal jumper allows changing the input voltage range from 18~30 VDC to 10~18 VDC. A green LED on the front panel lights up when the LDM-1000 is powered on. A second green LED light indicates that the loop current is flowing. -
Page 5: Supply Voltage
4. 1. Supply Voltage The LDM-1000 supply voltage range is 18~30 VDC with the JP1 jumper in the storage position (as shipped position). Only this range (18~30VDC) can be used for 4-20mA output operation. The operating voltage may be changed to 10~18 VDC by installing internal jumper JP1 across both pins. -

LDM-1000 LVDT/RVDT Signal Conditioning Module 4. 2. Internal Switches There are two internal DIP switch sets (SW1 and SW2) on the PC board assembly of the LDM-1000. The tables below explain the switch positions and functions. Switch Set SW1 Function:... -
Page 7: Oscillator 'Sync' Mode
The Oscillator ‘Sync’ mode setting will depend on the number of LDM-1000’s and transducers in your system, and their physical locations. For a single LVDT or RVDT system you will be running the LDM-1000 in the Master (INT) mode. For systems with multiple LDM-1000’s, especially when they are co-located, and/or the interconnect cables between the LDM-1000’s and the... -

Page 10: Calibration Procedure
DC voltmeter, and a power supply (see “Supply Voltage” under the “Initial Setup Procedure” section of this manual) to the LDM-1000. Turn the power on and allow a 15 minute warm-up. Follow the procedure below: Disconnect the LVDT/RVDT primary wire from Terminal 1 of P1. - Page 11 TE Connectivity‘s obligations shall only be as set forth in TE Connectivity‘s Standard Terms and Conditions of Sale for this product and in no case will TE Connectivity be liable for any incidental, indirect or consequential damages arising out of the sale, resale, use or misuse of the product.
