The LVDT/RVDT Simulator is used to test LVDT (Linear Variable Differential Transformer) or RVDT (Rotary Variable Differential Transformer) sensors. Using a 0- 10VDC command signal input and an excitation (drive input), the unit provides two simulation outputs of 1-5VAC. An internal 3kHz oscillator can be used as an alternative excitation source. Both outputs are fully isolated.

The unit accepts power supply input from 4 to 32VDC. When the input voltage increases from 0-10VDC, the output voltage A increases from 1 to 5VAC and the output voltage B decreases from 5 to 1VAC. Factory settings for the offset (minimum) and span (maximum) are user adjustable. Different models provide different settling times and phase differences between inputs and outputs.

An LED indicates if the power is ON. The unit is conformal coated and available in a DIN rail mount enclosure.

In addition, Axiomatic is developing AX130410. It simulates an LVDT signal with high precision for use in various industrial applications. High precision is achieved by the use of FPGA technology. The signal conditioner generates two (2) isolated outputs of 1-5VAC. An internal oscillator outputs at 400Hz +/- 0.1% at 3VAC as an excitation source. Based on the command message, output voltage A increases from 1 to 5VAC and the output voltage B decreases from 5 to 1VAC. A key feature is quick configuration to permit use in different set ups by the end user. The LVDT simulator interfaces with CAN and Ethernet TCP/IP networks. Adjustments can be accomplished with the Axiomatic Electronic Assistant or a web-browser. A USB-C interface is also provided.
