Insert these thin, laminated RTDs in winding slots to detect high temperatures before insulation damage occurs. RTD manufacturer of temperature sensors continuously monitor conditions and provide the long term trend data that is necessary for making adjustments before unexpected alarms occur.
The sensing elements of stator RTDs extend through most of the body length to provide an average temperature reading. This eliminates the danger of a point-type sensor missing a localized hot spot. Six sensors are recommended for each motor, two per phase. Locate sensors near the hottest point of the windings for best performance.
Some models comply with European standards for electrical apparatus for potentially explosive atmospheres: ATEX Directive 94/9/EC EN 50 014: 1997, General requirements EN 50 019: 2000, Increased safety.
"Nivotemp 63 K + KN, 63 K-VA + KN-VA
Modern production facilities employ more and more plant automation systems and computerized controls. These allow the monitoring and control of hydraulic and lubricating systems. Traditional level controls are focused on pump protection i. e. a typical system is equipped with a level switching with one or two contacts. These contacts protect the pump from running dry in the event of leakage..
Modern systems provide the opportunity for a pro-active leakage control by the use of continuous signals.
An analog output of 4-20 mA signals continuous signals the fluid level. Deviations from the ""normal"" are detected instantly and can be transformed into many types of action. In case of a catastrophic failure such as a burst hose the pump could be shut down immediately rather then let it run until the traditional switch turns it off after a large volume of oil has spilt.
The Nivotemp 63 versions provide continuous analog signals for liquid level only or for level and temperature combined. They are available in two standard length or in 150mm increments. The flange dimensions are the standard ones used for filler/breathers ( DIN 24557/2). In addition the units can be combined with our Fluidcontrolterminal which makes oil care even more technically advanced.
The 63..VA versions are suitable for use with high water based liquids ( HFA).
