Macro Sensors’ DC 750 Series of 3/4 inch (19 mm) DC-operated LVDTs are designed for a wide range of position measurement applications. They use built-in electronics to provide the desirable features of an AC-LVDT, such as frictionless operation and dynamic response, with the added convenience and simplicity of DC input and precalibrated DC output. They are designed to operate in conjunction with PLCs, digital indicators, A/D converters, computer-based data processors, and QC data collection systems.
The DC 750 Series offers nine standard ranges from ±0.050 inch (±1.25 mm) to ±10 inches (±250 mm). The maximum linearity error for a DC 750 Series sensor is ±0.25% of full range output using a statistically best-fit straight line derived by the least squares method.
DC 750 Series sensors provide highly reliable, contactless operation with the high resolution, excellent repeatability, and low hysteresis associated with LVDT technology. Their exceptional reliability is a result of manufacturing processes and assembly techniques developed and optimized by Macro Sensors over many years of manufacturing LVDT sensors. Their stainless steel housings act as magnetic shields to reduce the effects of external AC magnetic fields, and their sealing meets IEC standard IP-62.
