Robust RDP transducers monitor sluice gate position

Linear Variable Differential Transducers (LVDTs) sealed to IP67 and signal cabling are additionally protected against mechanical damage, resulting in a robust device capable of accurate, reliable measurement of displacement that enjoys a long service life. The choice of 4~20mA signal output permits the use of long cable runs to a dry location for the associated signal processing and data logging equipment. An alternative approach is to use transducers operating using magnetostrictive principles.
