Elburn,
IL – Monitor’s capacitance-type
proximity switches are ideal for low cost level
detection and for installation in tight spaces.
They are easy to install and calibrate.
These devices are used to detect the presence or
absence of bulk solids and have round M30 threaded
housings. The thermoplastic polymer enclosures
have an IP67 rating.
Two models are available. The
Model PAC-30U accepts 20 – 265 VAC (45-65
Hz) power and is switch selectable for normally
open or normally closed
operation. The Model PDC-30 accepts 10-40 VDC power
and is available in PNP or NPN configuration.
All
capacitance-type proximity switches from Monitor
offer adjustable sensing distance from 4 to 25
mm, and carry Monitor’s two-year
warranty.
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.
