protection analyzer measures, analyzes and reports critical performance
The automation experts
at ATC Diversified Electronics, maker of devices for automation, motor
protection, process monitoring and power quality, have introduced the new MPA2
motor protection analyzer. MPA2 is a micro-controlled, three-phase motor protection analyzer specifically designed to
protect electric loads and motors from failure and damage due to common current
and voltage faults.
The new MPA2 (FIG. 1) has some
major upgrades over the original version. New features include a two-line,
16-character LCD display for greater specificity and higher-quality information;
four front panel push buttons for operation/protection; standard RS485 Modbus
RTU communication protocol; flexible DIN rail or surface mounting options; a UL94V0
enclosure material; and access to a wide variety of reports, all at a lower
cost than the original.
investment in machinery is critical to all functions of an organization, as
maximized uptime impacts profits, quality and customer satisfaction. A
reliable, cost-effective method of monitoring motor health—and deactivating power
before a potential problem becomes catastrophic—is a necessity.
The MPA2 constantly
supervises current and voltage values. When any harmful condition occurs, the
output connection is deactivated until the fault disappears, power line
conditions return to an acceptable level, and the motor has been completely
The MPA2 measures,
analyzes and reports critical information such as current, voltage, frequency,
power factor (PF), reactive power (KVA), real power (kW), and energy
consumption (kWh). Charting performance history enables a more-informed
scheduling of future maintenance.

dry rotary vane vacuum pumps
A modern vacuum technology must
convince users in their everyday operations with features such as
sustainability, performance and ergonomics. Atlas Copco has developed its new
DVS vacuum pump series (FIG.
2) with a focus on this requirement profile. The result: the DVS
models are oil-free, dry rotary vane pumps that guarantee emissions-free, quiet
operation and do not contaminate the processes.
The dry rotary vane vacuum pumps are ideally suited for a wide range of
applications, including packaging and pneumatic conveying processes, medical
systems and analytical equipment, as well as in pick and place for several
automated industries. In these work processes, the dry rotary vane pumps offer
their users specific advantages: the DVS models are quiet, low-wear and
energy-saving, and take up very little space. They are ideal for applications
in which high efficiency must be achieved at competitive costs.
This is achieved by the proven functional principle of the rotary vane pump
and by the use of robust materials. For example, a rotor with graphite blades
rotates inside the DVS pumps. The centrifugal forces press the vanes against
the inside of the housing wall and hermetically seal the chamber for a safe,
uninterrupted operating vacuum. Due to the high-quality graphite alloy, the
vacuum can be generated with minimal friction losses.
The efficient pump mechanism and the design ensure minimal wear; in turn, this
leads to long maintenance intervals and easy servicing of the DVS. In addition,
the vacuum pumps are designed for maximum operating times. The temperature
management also contributes to this: to reduce the temperature of the
discharged air, the exhaust air is passed through an air cooler.
The DVS series is also equipped with an inlet filter, non-return valve,
exhaust silencer, a noise-containing canopy and an energy-efficient IE3
electric motor. The interaction of these components forms the technological
basis for a reliable pump with maximum vacuum performance and lower lifecycle
costs. The dry rotary vane vacuum pumps of the DVS series are available with a
nominal suction volume flow of 5 m3/hr–140 m3/hr and an ultimate vacuum of up
to 120 mbar(a)–150
mbar(a). For higher flowrates, the company recommends its dry claw vacuum pumps
and systems of the DZS series.

Improved photoelectric sensors
boost performance and capabilities
IDEC Corp. has introduced the SA2E general-purpose
photoelectric (PE) sensor family, in five major models, each improving on or
replacing proven SA1E products. A new ASIC, common to the entire offering,
provides a significantly improved price/performance ratio, while delivering better
response times and more capable detection.
SA2E PE sensors (FIG. 4) are offered in five major variations:
The SA2E sensors generally improve response times to 0.5 msec
with 1 msec for previous generation models—for better detection of smaller and faster moving
objects. Sensors are switchable between “light-on” and “dark-on” operating
modes, and applicable models have an on-board sensitivity or range adjustment
potentiometer. Depending on the model, sensing distances can range up to 20 m
for through-beam, up to 5 m for retro-reflective, and between 10 mm and 1,000 mm
for other reflective models. Tighter beams and more adjustability help
designers deploy the sensors in a greater variety of applications.
Electrically, the control output is connectable as an NPN/PNP
open collector with output reverse-polarity protection. The devices consume
very low current on the order of 20 mA–35 mA, at supply voltages of 12 VDC–24 VDC, with the ability
to switch up to a maximum of 100 mA. Designers can choose models with cables or
on-board M8 connectors for use with straight and right-angle cables.
SA2E PE sensors are extremely compact at 10.8 mm × 19.5 mm × 31.5 mm, and various
mounting brackets are available. Sensors are built to operate in a wide range
of temperatures from –30°C to 55°C, and an optional air
blower allows stable detection, even in dusty or misty environments.
IDEC SA2E PE sensors provide a superior price/performance
detection option for original equipment manufacturer (OEM) machinery, material
handling equipment, freight elevators, automated guided vehicles, robotics,
pick-and-place systems, packaging machines, and many other types of
IDEC also offers a wide variety of other complementary
control and automation products to help users best meet their requirements. As
with all its products, IDEC provides free tech support for its SA2E series PE
sensors. For more information, go to https://lp.idec.com/SA2E-Miniature-US.html.
