The Model 2A Thermocouple Sensor tube consists of a tube containing a filament heated by the passage of a constant current. A thermocouple is welded to the center of this heated element thereby providing a means of directly measuring the element temperature in terms of voltage output. For any constant value of current through the filament, the temperature of the filament increases as the pressure in the tube is reduced. The thermocouple voltage is directly proportional to the increased temperature of the filament, and thus generates an increase in voltage. Sensitive circuitry includes the thermocouple output directly in microns. The standard sensor tube has nickel-plated, forged-brass housing which makes it capable of withstanding 150 psi overpressure. All thermocouple elements are preoxidized under controlled conditions to provide interchangeability of tubes without recalibration. This process also provides high stability and minimizes the effect of contamination. Stainless steel versions are available.

The PT Compact USB is an additional member of the tecsis PT Compact series. The measuring range can be programmed according to the customers demands with especially developed software. The communication between the thermometer and a PC is done via an USB connection. Programming-Kits are not needed.
There are two models of the PT Compact USB. The standard model for temperatures from –50°C up to +200°C and a high temperature model for temperatures up to +600°C, which includes a 100 mm neck tube. The output signal of the PT Compact USB is an analogue 4…20 mA signal.
In order to program the measuring range, it is necessary to remove the measuring insert from the housing. The USB-interface is placed directly on the electronic board of the thermometer.
Precautions have to be taken to avoid ESD-damages, while programming the electronics. You do not have to remove the thermowell of the PT Compact, in order to program the range, thus you do not have to stop your process.

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.

Ni1000SOT is a nickel thin film resistance temperature detector (RTD) that is suitable for use in contact temperature sensing. The devices are manufactured by PVD-deposition on a silicon substrate. The thin film structure is covered by a passivation layer for environmental protection and enhanced stability. The nickel elements are mounted on lead frames and encapsulated in SOT23 packages. This technology allows the production of miniature, low cost, high precision temperature sensors. The characteristics of the temperature sensor comply with the former DIN 43760 standard. It is qualified for the most demanding automotive applications (incl. exposure to hot oil) and is suitable for many more applications in harsh environments.
Features:
- Contact temperature sensing
- Comply with former DIN 43760 standard
- Small SMD package SOT 23

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.
