The letters LVDT are an acronym for Linear Variable Differential Transformer, a common type of electromechanical transducer that can convert the rectilinear motion of an object to which it is coupled mechanically into a corresponding electrical signal. LVDT linear position sensors are readily available that can measure movements as small as a few millionths of an inch up to several inches, but are also capable of measuring positions up to ±20 inches (±0.5 m).

LVDTs have certain significant features and benefits, most of which derive from its fundamental physical principles of operation or from the materials and techniques used in its construction.

1. Do you have a signal conditioner that will source up to an 800 mA output?
No. The highest outputs available are 100 mADC non-isolated (API 4010 G) and 50 mADC isolated (API 4300 G). The API 4300 G EXTSUP will sink up to 200 mADC with an external power supply.

2. We have a 4-20 mA input and require 4 set points at the output. Do you have a product for this?
Yes, you can connect 2 of our API 1020 G units in series in the 4-20 mA input loop since the input impedance for current is 50 ohms and the drop is very low.

1. Do you have a product that can provide an output signal of 5 KHz, 50% duty cycle, 20 mA max and 24 V p-p max with no input?
Yes, the API 7500G M03.

2. We have an application which requires a signal conversion of ½ Hz to 6 Hz input to a DC output. Do you have a signal conditioner to do this?
No. The minimum input frequency range that we offer is 0 to 15 Hz.
