Switch amplifiers for intrinsically
safe applications
Pepperl+Fuchs

The new KFU8-SR-EX* (photo) is a
universal powered switch amplifier that
can be used in intrinsically safe applications
and functional safety installations
up to safety integrity level (SIL) 2.
The new KFU8 device can be supplied
with 19 to 30 V d.c. or 90 to 253 V a.c.
With this functionality, a single device
can be used with various supply voltages.
As a result, fewer components
need to be kept in stock and in the
field technician's toolbox. The switch
amplifiers transmit discrete signals
from NAMUR sensors or mechanical
contacts in the hazardous area to the
safe area. A proximity sensor or switch
controls the load on the control side via
a changeover relay contact. All modules
feature line fault detection. In the
event of a fault, the relays de-energize
and the fault is indicated by LEDs. -

This centrifugal sifter addresses
labor-shortage costs
Hans Turck
The Centri-Sifter M1 (photo) is a centrifugal
sifter specially designed to help
address the high costs associated with
maintenance and recruiting, training
and retaining skilled labor. The CentriSifter
M1 sifts, scalps, de-agglomerates
and dewaters granular materials
ranging from dry bulk solids to solidsladen
slurries. Centri-Sifter M1 is said
to be the only centrifugal sifter on the
market engineered for one-person operation
and maintenance, which can
help reduce the high cost of skilled
labor. The Centri-Sifter M1 features a
capacity of up to 15,000 lb/h of dry
material and up to 50 lb/h of wet. -

Programmable, multicolor
LED indicators
Dwyer Instruments
This company is expanding its portfolio
of light-emitting diode (LED) lights with
the robust LED indicators of the K100
series (photo). The 100-mm beacons
- developed by partner company
Banner Engineering - are available in
two configurations. The Pro Daylight
Visible beacon model offers 12 audible
options and has a clear lens that
avoids false indications, even in sunlight.
It offers bright indication in both

indoor and outdoor environments. It
features three color options (green,
yellow and red) for status indication,
operator guidance and other functions.
The K100 Pro Indicator model
has a diffused lens that appears white
when inactive, thereby preventing false
indication. It features 14 color options
that can be used for status and indication.
Both beacon models can include
an optional audible alarm and have an
IP66 environmental rating. - Hans

This field-configurable flowmeter
has no pipe-run requirements
The new Series PI (photo) is a variablearea
flowmeter that utilizes a springloaded
piston. The fluid flow in the
application causes this piston to move
along the axis of a precision-tapered
shaft, creating a variable orifice in direct
proportion to the flowrate. The
piston is mechanically linked to a readout
pointer and actuates switches or
a transmitter. Straight pipe runs are
not required before or after the meter,
allowing for installation in areas with
minimal space. The three-wire version
of the Series PI is equipped with a
solid-state relay that can be configured
in the field for alarm output. - Dwyer

This humidity sensor is
designed for industrial drying
The HYT 939P temperature and humidity
sensor (photo) is equipped with
a PTFE filter, which makes it well-suited
for industrial drying applications. The
sensor's compact housing allows for
easy positioning within the monitored
process, while the filter minimizes the
influence of particulate matter and
volatile organic compounds on the
humidity sensor. The sensor is based
on a capacitive-polymer measurement
principle with a fast response time,
low drift and hysteresis. The sensor
remains stable in a high-humidity environment
and can sustain condensation
conditions. It comes fully calibrated
and temperature-compensated. - Innovative
