Results:
Evaluator claims sensors will
respond to any liquid after threshold is exceeded.
Comments:
The Magnetrol Model 918 has not
been evaluated for application with petroleum hydrocarbons.
The sensor has been evaluated specifically for application in water,
acetone, and trichloroethylene.
The
ABB Automation Freelance 2000 was used to detect the 8 to 16 milliamp change
that occurred in the Magnetrol sensor when it became submerged in product.
Audible and visual alarms were activated when the sensor indicated that
alarm conditions were present.
