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.

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.

The ifm temperature sensors are based on a PT 1000 which converts the measured quantity of temperature into a signal as a result of the change in resistance. A microprocessor controls the evaluation of the electrical signal. For the efector 600 the system temperature is directly indicated on the unit by an LED display.
The electronic circuitry is made in film technology, i.e. a flexible, temperature-stable and extremely resistant polyimide film is used as a carrier for the SMD components. In conjunction with a special potting compound this leads to a high shock and vibration resistance. The microprocessor and the display make the handling of the efector 600 very simple. By means of programming buttons the values for switch point, hysteresis, switching frequency and delay time can be set electronically without the system temperature being present. This enables the installation of the efector 600 in a few minutes. The values are saved in an EEPROM independently of the supply voltage.

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.

Autoclave Chamber/Load Probe (SL160) Sensor :
The SL160 series of autoclave chamber/load probe sensors are similar to the SL150 series, but differ in having a 90° bend and a chisel point to allow penetration of the product bottle seal.
When mounting a load probe with a straight sheath into a product bottle/container in an autoclave it is often difficult to achieve the desirable orientation. This is often due to both the weight of the probe lead wire and its restrictive bending radius. The SL160 is designed to circumvent this by having a 90° bend in the probe sheath. The addition of a chisel point at the probe tip also allows it to be inserted with relative ease through the bottle seal it there is one.
The SL160 chamber/load probes are currently being fitted as original equipment by a major autoclave manufacturer.

A critical indication of the status of bearings on large rotating plant is provided by their running temperature.
Monitoring bearings in this manner provides the ability to recognise any possible upward trend in bearing temperature. This in turn allows for a regime of planned preventative maintainance to be put in place, offsetting the possibility of catastrophic plant failure.
Due to its small physical size the miniature bearing sensor can be positioned close to the bearing surface allowing it to sense any early change in temperature.
These devices are available in both thermocouple and PT100 resistance thermometer format and can be supplied as either single or duplex sensors. The sensor lead wire insulation is in PTFE or glass fibre and lead wire jackets can be protected with stainless steel outer braid.

Freeze Dryer (FD100) Sensor :
The FD100 freeze dryer sensor was designed to measure very small volumes of liquid product, typically like those found in lyophilizers.
When attempting to accurately measure the temperature of small volumes of product such as that contained in a pharmaceutical vial, temperature conductance can affect the result. This is due to the relatively large mass of the sensor sheath compared to the volume of product being measured.
The FD100 sensor was designed to reduce this effect and is achieved by building a thermal break between the sensing tip and the main probe stem. Temperature conductance is kept to a minimum and the positioning of the face of the miniature detector ensures an optimum time response.

Autoclave Drain/Air Filter (SD050) or Freezer (SD051) Sensor :
The SD050 series drain/air detector and freezer sensor is not presented with the same demanding conditions that are experienced by the chamber/load probe.
However the critical measurement that they transmit to the control system requires no less an integrity than that for the chamber or load probe. To maintain this integrity the same manufacturing programme as that used for the chamber and load probes is performed.
The SD050 sensors are used extensively in autoclaves manufactured by most of the major manufacturers either as original equipment or as replacement parts.
At the other end of the temperature spectrum the SD051 is designed for use in pharmaceutical freezers, refrigerators and incubators.
