Background
Pyrosales Resistance
Temperature Detectors (RTD’S) are specially designed to ensure precise and
repeatable temperature versus resistance characteristics. The sensors are constructed
in a unique strain-free manner, and use only high quality RTD
elements. Ceramic wire-wound elements, flat film technology elements or military
spec anti-vibration elements are used as per customers requirement to ensure
the most suitable specification is supplied.
Features and Benefits
Accuracy
A special process combines strain-free construction with full
winding support for dependable, accurate readings in standard RTD
elements, and in flat film elements where platinum is etched onto a substrate.
High Signal-to-Noise Output
High signal-to-noise output increases the accuracy of data
transmission and permits greater distances between the sensor and the measuring
equipment.
Interchangeability
Strain-free construction and precision trimming allow
elements from different lots to be substituted without recalibration.
Sensitivity
Self-heating is minimised, allowing precise measurement. The
temperature coefficient (alpha) is carefully controlled at the industry standard
while insulation resistance values exceed IEC-751 standards.
Standardisation
Elements are available to meet or exceed the requirements of
various standardisation agencies. IEC- 751 standard tolerance classes A and B
respectively are very well suited for industrial applications. Tolerance classes
up to 1/10th DIN can also be supplied where higher accuracy is demanded
Physical and Chemical Stability
Physical and chemical stability over a wide temperature range
is ensured by Pyrosales
highly controlled manufacturing process. Standard elements are built to resist
mechanical vibration and shock, however where there is high exposure to mechanical
vibration, specially manufactured military specification thick film RTD
elements can be supplied to suit the application.
Repeatability
All elements exceed IEC-751 repeatability values even after
long exposure to temperatures within the operating range.
