About the SI-Series General purpose 4-20 mA LVDT position sensor
The SI 750 Series of 3/4 inch diameter, loop-powered 4-20 mA LVDT position transmitters is designed for a wide range of position monitoring and feedback applications.
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.
Available in standard ranges of 1 inch (25 mm) to 20 inches (500 mm), the maximum linearity error for an SI 750 Series sensor is ±0.25% of full range output using a statistically best-fit straight line derived by the least squares method.
SI 750 Series transmitters offer the frictionless operation, high resolution, excellent repeatability, and low hysteresis associated with LVDT technology, along with the convenience and simplicity of a precalibrated 4-20 mA current loop operation. The built-in electronics operate over a wide range of loop supply voltages and resistances, and are designed to operate with many PLCs, digital indicators, A/D converters, computer based data processors, and QC data collection systems.
