NewTek Hermetically-Sealed AC-LVDTs Offer a Safe Solution for Position Measurement in High-Risk Areas
Constructed without internal electronics, AC-operated LVDTs operate reliably in industrial applications with high, low or unpredictable temperature fluctuations, shock, vibration, and chemical, or radiation exposure. While the AC-operated LVDTs operate in a hostile area, feedback is retrieved by an LVDT Signal Conditioner that converts it to a digital signal for use in a computer or programmable logic controller located in a benign area.
For example, LVDT Position Sensors used in the process control systems of paper mills provide dimensional feedback on the tension arm or roller position to control product thickness. The paper mills pose dangers to operators with larger rollers moving at high speeds, caustic and corrosive fluids splashing in unpredictable places, and temperatures fluctuating at different points in the process.
