The hazardous location model of the SafePoint fail-safe rotary paddle level switch is a practical solution for confined storage areas, like indoor hoppers and bins that may contain high levels of dust. Monitor Technologies’ SafePoint level switch with a self-validating design detects material presence or absence, as well as continuously monitors its own ability to function. This analysis includes sensor health and system power failure, which makes the SafePoint truly “fail-safe”. The unit provides a relay output signal condition if a sensor failure occurs or upon loss of input power. 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 and confirmation of proper operation. Other features of the SafePoint bin level switch include its rugged construction, twist on/off cover for bolt free removal, and motor shut-off when paddle becomes impeded to maximize motor life.
