Honeywell’s Linear Hall-Effect Sensors may potentially be used in several industrial applications, including tamper prevention in utility meters. Thieves sometimes attempt to bypass the operation of an electric, gas or water meter by attaching a strong magnet to it. The utility usage is underestimated when the magnet saturates the current transformer or slows the spinning wheel. Install Honeywell’s Linear Hall-Effect Sensor ICs in multiple locations inside the meter to detect the abnormal presence of a magnetic field. Send an alarm to the utility company or record this fraudulent activity in memory for access at a later date.
