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.

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.

Design and fabrication of our industrial sensors correspond
with the technical standard of DIN 43770. Our sensors can
be divided into two groups, depending on the measurement
method used.
Resistance thermometer
Resistance thermometer have a defined resistance value
at 0°C which alters, depending on temperature.
This alteration is presented as temperature value.
Thermo couples
Thermo couples consist of two different metal wires which
are welded together at one point. When the weld spot is
heated, a thermal voltage is generated at the open ends
of the wires which provides the temperature measurement.
The sensors have a modular design and consist of
• a connection head
• a protective tube
• a replaceable measurement insert.
The connection head for wiring is the standard head of shape B. The protective tube and the measurement insert of the sensor vary, depending on application conditions and temperature range.

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.

Miniature Bearing Sensors are designed to monitor temperature of embedded bearings critical to machine performance in industrial rotating equipment. The most reliable indicator of bearing condition is the temperature of the metal beneath the bearing shoe. Rising temperatures indicates the breakdown of the lubricating oil film. Quick identification of this condition allows machine shutdown and maintenance to occur before catastrophic failure of the bearing itself. Typical applications for bearing sensors include motors, turbines, pumps, gear boxes and other journal bearing pedestals.
