A highly efficient electric
double-diaphragm pump
Quantm is a new electric-operated
double diaphragm pump (photo) that
features an advanced electric-motor
design that is said to be significantly
more efficient than a standard pneumatic
pump. The pumps' FluxCore
motors and drives deliver up to eight
times more continuous torque at low
speeds than conventional motors, the
company says. The pump offers a
wide range of materials of construction
to support multiple industrial
and hygienic applications, including
chemical processing, water treatment,
paint manufacturing, pharmaceuticals
and more. Designed to be a drop-in
replacement for current pneumatic
pumps or for greenfield construction,
the pump is built for harsh industrial
or hygienic environments, while also
being lightweight and easy to maintain.

These temperature and vibration
devices have new certifications
This company has recently received
FCC, FM and IC certification for its
NEON brand of temperature transmitters
(photo) and vibration sensors.
The NEON vibration sensor sends
alerts to maintenance engineers as
soon as assets, such as engines,
conveyor belts and pumps, start to
fail. This sets off a trigger when a
change of amplitude is detected in
the vibration spectrum or when outliers
in the data occur. An engineer
is alerted to check on this asset to
prevent it
from failure or long-term
damage, which saves costs and ensures
operational uptime. The NEON
temperature transmitter is designed
to be implemented quickly, and to
transmit a signal for monitoring purposes
via connection to an industrial
thermocouple or RTD. The device
can be connected to a thermocouple
via an M12 connector with an up to
3-m-long extension cable. It uses onboard
intelligence to determine average
values over user-determined time
scales to provide insights that can be
TLV
used directly within existing systems.

A digital sensor that measures
subcooling and superheating
This company's new digital pressuretemperature
sensor (DPTS; photo) is
designed to measure subcooling for
HVAC-refrigeration applications. The
DPTS is a self-contained device that
measures pressure and temperature
and calculates subcooling based on
refrigerant type. It is compatible with
safety-group A1, A2 and A2L refrigerants.
The latest-generation DPTS
can read maximum pressure between
500 and 700 psi. The DPTS
is available as a superheat sensor
as well. In a HVAC-R system, two
DPTS sensors can be used to measure
superheating and subcooling.
Superheat measurements monitor
the efficiency of the system and can
be used as a safety sensor to protect
the compressor from liquid flooding.
Subcooling measurements monitor
the refrigerant charge level and control
the high-pressure flow-control
valve to maintain the condenser mass
flowrate. - DunAn Microstaq, Inc.,

Get steam at its set pressure,
nearly immediately
The MC-COS multi-control valve
(photo) is a fully integrated device consisting
of this company's COS pressure-reducing
valve, a separator, steam
trap and a motorized actuator. It is designed
for steam conditioning, as well
as to control either the steam pressure
or temperature of steam-heated processes.
A major benefit of the MC-COS
is its ability to instantaneously supply
steam at the set pressure - when the
pressure set value is changed, the new
target can be achieved quickly and accurately.
The system's feedback-control
configuration, as well as its servomotor-driven
actuator with proprietary
algorithms, contributes to fast response
and avoidance of overshooting and undershooting.
The system is appropriate
for automated processes requiring that
supplied steam be at a stable pressure,
and processes with frequent fluctuations
in the pressure setting, including
corrugation machinery, dryers, presses
and jacketed equipment. - TLV Corp.,
