Trans-Tek, Inc. Series 1000 - Oscillator/Demodulators 1000-0012

The Series 1000-0012 Oscillator/Demodulator from Trans-Tek, Inc. is designed to provide electrical support for AC LVDTs, generating a stable sinusoidal excitation voltage from an unregulated DC input. It features a phase sensitive demodulator with automatic phase synchronization, eliminating the need for manual phase angle adjustments during installation. The module includes a three-pole active filter to minimize output ripple while maintaining high frequency response. This model operates with a dual DC input voltage of ¬±14.5 to ¬±28 VDC and can drive LVDTs with a primary impedance of 100 Ohms or greater. The oscillator output voltage is adjustable between 4.25 to 5.75 VRMS, and the DC output voltage is limited to ¬±12 VDC, providing a maximum current output of ¬±3 mA without distortion. The device also supports a 4-20 mA output for LVDTs with a sensitivity of 0.5 V/V, with a minimum full-scale output current ranging from 2 to 22 mA. The operating temperature range is from +32 ¬8F to +158 ¬8F (0 ¬8C to +70 ¬8C), and it includes features such as zero and span controls, full encapsulation, and self-locking terminal strips for secure connections. This product is suitable for applications requiring precise LVDT measurements and reliable performance in various environmental conditions.
