Detecting electrical anomalies has never been this simple, affordable and
cost effective. No settings required to record valuable information.

In a week, this 150 HP motor was in operation near 13 hours. It had 497 starts! 85 were suspicious and were automatically highlighted by MerMaid (Motor Event Recorder).

Who would like to be the supplier of a motor controlled this way? Who would like to be its owner? Like in most case, the electrician cannot correct the problem if he is not aware of the symptoms. The best time to correct a problem is before the equipment fails, not after!

65 large corporations, like GE, Bombardier, Kruger and Alcan, tried MerMaid for few weeks. The installation is non intrusive and takes less than 3 minutes. Over 200 motors, pumps, compressors, fans, conveyors and other type of vital equipments were monitored. 32% had behaviours like above, often and every day! Another 18% had behaviours like this once or twice a week! Only 50% were operating as expected! In addition, 17% of these equipments were highly unbalanced. Would you like to know what would fail next?

How well balanced is the current or the voltage? Do you really think that the power utility is supplying what you are paying for? MerMaid is an event based battery operated recorder. If the value doesn't change, why filling the memory with it? It records an average of 1 week to 3 months of data, before the memory rolls over. More than enough to find the type of problems that consume 95% of the troubleshooting time of electricians. It is perfect to be sure that a new installation performs as specified. MerMaid will work non-stop 4 to 6 months on 2 inexpensive alkaline batteries type C!

Being the ONLY affordable instrument able to monitor all the phases of 3 motors at the same time, MerMaid really helps when it is practical to compare the operation of different equipment. This graph shows the average current used by 3 identical pumps in a wastewater lift station over an hour. It is so easy to see that one pump do not perform like the two others.

Many PLC programming errors were found this way. User definable graphic templates can be created to highlight specific problem.

Even if MerMaid is a recorder, you can see in real time what goes on like never before. Connect MerMaid to a wireless transmitter and check your equipment remotely. Let MerMaid tell you when the values exceed your set points. Stop wasting valuable time waiting for intermittent problems to occur.

When is it time to change old equipment? When it costs more to keep it than to buy a new one. Most experts agree that 95% of the total cost of a motor will be its power consumption. What is the cost the old one? A power recorder can become a very valuable tool. MerMaid allows the user to enter manually the equipment's voltage or to use our voltage sensor in order to calculate power.

With a VFD, it can be useful to know the frequency powering the equipment. Most settings are context sensitive and automatically display when the user touches a dial.The settings are entered when its time to display something, not before installing the unit, therefore, it is impossible to make a costly bad setup.

MerMaid has 5 other inputs that can be configured for specific needs and valuable instrument data like battery status and internal temperature (which is mostly used as an indication of the temperature of the control panel) are also supplied. When connected to AC, MerMaid uses this to detect power failures. When operating on batteries, MerMaid uses an antenna to detect 50-60 Hz inside the control panel to detect power failures. The glass effect is part of the many display preferences.

MerMaid fits where no other recorders fit.

And you thought that we forgot the display? The data cumulated can be transfered in batch or real time to a Windows software using MerMaid's RS232 serial port. The data can also be transfered by infrared communication or cable to a Palm. The powerfull MerMaid software for Palm allows the electrician to verify, analyze and diagnose electrical behaviour without requiring a fragile and expensive laptop on site. Several screens allow to rapidely compare current on all the phases of several motors. The same screen is usefull if clamps are installed at different locations on the same electrical equipment in order to detect more rapidely the origin of a permanent or intermittent problem.

MerMaid, the preferred predictive and intermittent problem maintenance tool.

*The POWER CONVERTER option is required, but it can be entered manually in the MerMaid for Windows software
