Capacitive Proximity Switch Fits In Tight Spaces for Bin Level Detection
The Model PAC30U and PDC30 capacitive style proximity switches from Monitor Technologies are new bin level detection devices for tight spaces and dry free-flowing powders and granular materials. The capacitive style proximity switch operates by detecting a change in capacitance as the material to be detected comes within close proximity or contact with the switch. These devices can be used in many applications where the granular or powder material is dry and free-flowing and has a dielectric constant within an adequate range. In addition, these devices are ideal level indicators where tight spaces exist at the desired mounting point. They are also relatively low in cost.
The Model PAC30U is a universal AC operated device (20-265VAC) and the PDC30 is DC (10-40VDC) operated. Both units are provided with a 30mm process connection and adjustable sensitivity. The PAC30U is UL listed for ordinary locations and both the PAC30U and the PDC30 carry the CE Mark and are warranted for 2 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.
