HANDHELD
TACHOMETERS

PROXIMITY SENSORS

Prosense Basic series proximity sensors are made
from nickel-plated brass and available in barrel
sizes from 8- to 30-mm. Flush- and non-flushmount styles are available in sensing distances to
15 mm and offer an LCP (liquid crystal polymer)
active face. PNP logic models are available with
either a N.O. or N.C. output; NPN logic is also
available with a N.O. output. M12 quick-disconnect
or 2-m pigtail termination styles are available for
all sizes.

Three tachometers expand
options for gathering
condition-monitoring
data. Models TKRT 21
and TKRT 31 are digital
units, while the TKRT
25M is mechanical. All
are compact, have large
displays, and can be
operated with one hand.
The TKRT 21 uses laser
or contact measurement to determine rotational and linear speeds, allowing
measurement at a safe distance from machinery. The instrument offers high speed
and distance versatility in several measurement modes. TKRT 31 is more advanced
and measures rotational and linear speeds and distances. The TKRT 25M
mechanical version uses precise contact measurement to determine rotational and
linear speed of equipment such as engines, shafts, and conveyor belts. It requires
no batteries and has a large, easy-to-read dial gauge display.

SAFETY RELAY MODULE

HR6S safety relay module is a microcomputer-based
device supporting a wide variety of connections,
input devices, and operating modes while adding
diagnostic and status monitoring. The module design
meets ISO 13849 requirements, with one model for
low-risk Safety Category 1 applications, and six
models suitable for high-risk Safety Category 3 and 4
processes requiring redundancy.

The StaCool vest core-body-cooling system keeps users cool,
comfortable, and productive without compromising mobility. Vests are
made from breathable Airprene material for comfort and flexibility and
include ThermoPak inserts to cool the body core. The vest provides as
much as 3 hr. of cooling per ThermoPak set, depending on activity type,
environmental conditions, and body heat.

RANGER is a battery- or solar-powered
LTE-M transmitter that powers sensors
and transmits their measurements over
LTE-M cellular networks using the MQTT/
Sparkplug messaging structure to bring
data into a SignalFire cloud or an existing
platform. New modules add capabilities
for interfacing with HART & SDI-12
communication standards. The unit can
power 15 HART devices when equipped
with the HART expansion module and
eight devices using the SDI-12 expansion
module (depending on the current draw
of each device). Using this option, users
can choose from a wider variety of sensors
that best fit their application and reduce
installation costs by using a multi-protocol
sensor-to-cloud platform.
