WORM Flexible Temperature Sensor
Unlike straight temperature sensors, our WORM flexible RTD and thermocouple temperature sensors bend and slide right into a thermowell without having to remove the enclosure or assembly components.
|
|
RTD's are stable and have a fairly wide temperature range, but are not as rugged and inexpensive as thermocouples. Since they require the use of electric current to make measurements, RTD's are subject to inaccuracies from self-heating.
An RTD capitalizes on the fact that the electrical resistance of a material changes as its temperature changes. RTD's rely on the resistance change in a metal. The resistance will rise more or less linearly with temperature.
Traditionally, RTD's use a length of conductor (platinum, nickel iron or copper) wound around an insulator. Newer styles use a thin film of the conductor deposited on a ceramic substrate.

Insert these thin, laminated RTDs in winding slots to detect high temperatures before insulation damage occurs. RTD 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.

The bearings of industrial rotating equipment operate under arduous conditions - often for considerable periods of time. The most reliable indicator of bearing condition is the temperature of the metal beneath the shoe.
Recognition of rising temperature can provide a warning of the breakdown of the lubricating oil film; thus allowing machine shutdown and maintenance to take place - avoiding the probable catastrophic failure of the bearing and possible damage to its mounting. Conax Miniature Bearing Sensors provide a simple and cost-effective method to monitor bearing temperatures.
Features:
- For embedded applications in rotating machines
- RTDs - 100 ohm platinum, 0.00385 ohm/ohm/°C
- Thermocouples types J, K, T & E
- Single and duplex sensors
- Various styles and sizes
- Operating Temperature: to 250° F ( 120° C)

Install miniature sensors in or beneath the babbitt layer of bearing shoes. They monitor metal temperature — the most reliable indicator of bearing condition — to give early warning of oil film breakdown. Machines can then be shut down and the problem corrected before catastrophic failure occurs.
While no larger than many bare ceramic elements, these RTDs have metal cases and insulated leads to withstand rough handling and harsh environments. They’re easy to install in drilled holes for general purpose sensing.
