Self-Validating Point Level Sensor is Truely "Fail-Safe"!
When high level sensors fail, it can be costly if you find out about it when your silo overfills. The cost of an overfilled silo is estimated to be $5,000, including material loss, cleanup, lost production and even regulatory costs. SafePoint® point level sensors are self-validating devices that continuously monitor their ability to function. If failure is detected an output will indicate to that this condition exists, providing you the warning needed to prevent a spill. Self-validating point level sensors, like the SafePoint from Monitor Technologies, has been safely monitoring high level conditions in grain processing facilities for many years.
The
SafePoint rotary paddle level switch with a self-validating design
detects material presence plus continuously monitors its own ability
to function. The analysis includes sensor health and system power
failure, which makes the SafePoint truly “fail-safe”.
The SafePoint incorporates patented use of Hall-Effect technology,
dual outputs to indicate both material presence and unit health,
and microcontroller technology to continuously protect bulk solids
processing and storage from the consequences of unknown sensor
failure by providing immediate indication of a sensor failure
and confirmation of proper operation.
Other practical features of the SafePoint include rugged construction,
motor shut-off when paddle becomes impeded to maximize motor life, twist On/Off
cover for bolt free removal, and local status indicating light (except hazardous
location models)
A practical application for the SafePoint would be to use this "true"
fail-safe product if undetected sensor failure could result in a
catastrophic process problem.
