Case Study 4: Directional Logic for Significant Temperature Extremes

Situation A naval application required the ability to determine direction of target movement (in this case the propeller). Typically, this would be accomplished through the use of a dual channel zero speed sensor, however this application was outside the standard operating temperature range (-40C) and required the ability to operate in cryogenic temperatures. Solution The […]

Case Study 3: Replacement Sensor for Hazardous Location

Situation A leading turbine manufacturer has been using a non-intrinsically safe variable reluctance speed sensor and preamplifier for its standard product offering. New requirements call for the installation of an ATEX-certified intrinsically safe solution for a portion of their applications. Initial quantities are limited and the required time to market is 4 weeks. Solution- an […]

Case Study 1: Moisture Intrusion

Solution Moisture can be detrimental to speed sensor operation, ingressing into the sensor body and creating a destructive impact to sensor components and solder connections. A leading manufacturer of turbine flowmeters was experiencing speed sensor failures due to moisture ingress from atmospheric conditions on an offshore oil rig. Moisture was ingressing through the sensor tip […]
