Position sensors eliminate failures in valve control
This company’s linear variable displacement transducers (LVDTs) are designed with an isolation-tube format (photo) to ensure reliable displacement feedback of hydraulic/non-hydraulic pumps and valves. The isolation tube protects the LVDT core from pressurized environments and fluids when the sensor measures pump flow or valve position (open/closed). The position sensor provides electronic feedback as part of a process control system. In the isolation-tube configuration, only the LVDT core lies inside the harsh area or media. Constructed of metal, the core can withstand exposure to a variety of fluids and pressures so that the chance of LVDT core failure is virtually nonexistent. With sensor windings in near ambient conditions, there is a low risk of unit failure. — NewTek Sensor Solutions, Pennsauken, N.J.
