MerMaid (Motors & Events Recorder) is a three phases X three motors
(or other equipment) current, voltage, frequency, digital and analog
recorder system. It simultaneously examines all phases at the same time
of several electrical equipment and monitors.
It fits where no other recorder will.
Most
control panels do not have the internal space or available power
required to leave an electrical datalogger inside for a long period of
time. Sometimes, to catch an intermittent problem or to monitor
specific equipment, there is no choice but to leave an expensive power
metering instrument outside an open panel for a long period of time.
MerMaid is 5 times smaller than the average power analyzer and will
operate for 4 months non stop (under normal conditions) on 2
inexpensive user replaceable internal batteries. With rechargeable
batteries, AC power and integrated DIN rail attachment, it’s ideal for
permanent installation. An optional internal modem is also available.
Find problems 3 times faster
In
some cases, the problem is caused by a sequence of operation of
multiple pieces of equipment. It is difficult to find these problems if
only one piece of equipment is monitored. Problems are also caused by
operator’s behavior, limit switches or when a pressure, temperature or
other actions take place. The basic MerMaid (with the appropriate
sensors) can monitor the current and frequency for 3 phases on 3
motors, pumps or other electrical equipments simultaneously, plus has 4
digital inputs, 1 analog input and 1 power failure input (when
operating on batteries). Power consumption is calculated by entering a
voltage in the software or by using an optional external three-phase
600V potential transformer connected to one of the motor input. All of
the motor inputs can be converted to 4-20mA, 0-5V, 0-12V or 0-24V with
an optional adapter. All inputs are viewed on an optional Palm
computer. Windows and Palm software are included.
Simple to use
Designed
by electricians for electricians, MerMaid uses intelligent recording
based on events or variations to record data, therefore no setting is
required eliminating the most common errors. The user simply needs to
use the right sensors for its application. MerMaid is so simple to use,
most will never read more than the one page quick guide.More Information
