LVDC Series - LVDT to Digital and RVDT to Digital Converters
Description
LVDT Displacement transducers accurately measure position and displacement. The strength of the LVDT is in its principle of operation. As LVDT sensors are inductive, there is no electrical connection across the sensor, which ensures clean, accurate data and a long life.
RVDTs provide an extremely reliable solution for precision angular displacement (position) measurements. They are used in circumstances where a physical quantity can be converted to rotary displacement. There is no direct contact between the moving and the stationary part of the device, which insures a long operational life.
The SLVT series are complete, low profile, continuously updating, single channel, isolated Digital to LVDT Converters used to simulate the output of LVDT's (Linear Velocity Displacement Transducers), RVDT's (Rotary...) and other phase/voltage sensitive AC devices. They provide very precise linear AC voltage outputs proportionate to the magnitude of the input data, in or out of phase respective of the AC reference input as determined by the MSB of the input word (offset binary format).
These converters are complete full functioning devices that require no trimming, padding components or signal conditioning. They provide a high drive capability of up to 2000 ohms, real-world voltage reference inputs, frequencies and signal output levels.
All units feature completely Transformer Isolated Reference Inputs and Signal Outputs, to eliminate ground loops, differing potentials, and to keep any high voltage transients frp, affecting the computer bus backplane, while assuring no interference with or between any devices the signals are connected to.
The SLVT Series feature virtually indestructible short-circuit proof outputs, overcurrent, short circuit protection and automatic thermal cutoff.
The output is crisp, continuous, monotonic, extremely stable, linear and precisely repeatable with very low ripple content. Because no switching or multiplexing is utilized, the output requires no additional filtering and does introduce or exhibit second frequency harmonics.
Standard units are provided with a two wire transfomrer output, center-tapped transformer outputs may be selected by adding a "-CT" to the end of the model number.
The gradient of the output is reflected as the output voltage/8192 for the out of phase range (negative displacement) and voltage/8192 +8192 for the inphase range (+, or positive displacement). The sum of the in-phase and out-of-phase ranges provide the total 14 Bit resolution. The data is MSB aligned.
