What Is an LVDT?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). Steam Turbine Position Sensor Cross Reference GE and Westinghouse Part Numbers to Macro Sensors LVRTs and LVDTs Model NumbersCross reference for OEM part numbers to Macro Sensors part numbers pertaining to GE and Siemens Westinghouse Steam Turbine Control Valve Position Sensors. This includes sensors for conditioning, stop, feed water boiler pump valves and other control valve position sensors in Steam Turbine Control systems.
Why Use An LVDT?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. Signal Conditioning FAQ - Thermocouple Inputs1. Will an API 4000 G work with an input temperature range of 1000 to 2000°F? Signal Conditioning FAQ - DC Inputs1. Do you have a signal conditioner that will source up to an 800 mA output? 2. We have a 4-20 mA input and require 4 set points at the output. Do you have a product for this? Signal Conditioning FAQ - RTD Inputs1. Do you have a temperature differential unit that will measure a difference of 10° C between the two inputs? Signal Conditioning FAQ - Frequency Inputs1. 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? 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? Signal Conditioning FAQ - Current Loop Inputs1. Are the API LPI-1 and the API LPI-2 UL recognized or listed? 2. We have an API DPI-2. Can we have an input of 0-20 mA and an output of 0-20 mA?
