These RTDs cover the full temperature scale of the international standard EN60751. Precision sensing elements and nickel alloy sheaths are capable of measurements from -200 to 850°C (-328 to 1562°F) with typical ice point drift less than ±0.05°C.
600°C models have stainless steel sheaths for reduced cost. They use the same element structure as 850°C models for excellent accuracy and stability.

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.

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.

In addition to long-term stability, interchangeability and accuracy, elementary sensors are additionally characterized by small size footprints of only a few square millimeters. The temperature application range, however, is extremely high: from -196° Celsius to +1000° Celsius!
To increase the ease of use in mass production applications, Heraeus Sensor Technology has enhanced the capabilities of elementary sensors. DBS sensors, for example, are equipped with rectangular connecting wires that offer superior directional stability when compared to round wires. The DBS sensors, which are available in several different standard wire lengths, can eliminate the need for expensive extension leads.
Ideas developed by Heraeus Sensor Technology have simplified the need for further processing of SMD sensors. The FC-type SMD sensor, for example, which have no edge-metallization, can be die-bonded on PCBs instead of soldered, saving time and costs for automated manufacturing processes.
