MAID Labs’ MerMaid 3 X Three-Phase Electric Analyzer
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.
What the users have found?
Based on a significant survey including hundreds of MerMaid’s monitored equipment owned by 65 large multinational companies or cities, 32 % of all equipment monitored had multiple abnormal operations every day and another 18% had this problem few times every week. Most of these anomalies were unknown because they were not permanently disturbing the production … yet. Is this the best time to correct these problems?
