Supported Applications
The Omega Glass Wire Wound Platinum RTD Elements series provides temperature measurement solutions using ceramic (KN) and glass (GX/GO) wire-wound platinum elements. The product overview identifies the ceramic series as suitable for high-temperature stability and shock resistance, while the glass series is described as suitable for low or very high temperatures with good vibration resistance.
Operating Conditions & Performance
The series encompasses two primary temperature ranges depending on the element construction. The ceramic (KN) elements operate from -200 to 600°C (-330 to 1110°F). The glass (GX/GO) elements cover a range of -220 to 400°C (-365 to 750°F), with specific models such as the 1PT100GX0518HG extending to 450°C. Accuracy is defined by IEC751 standards: Class A (IEC751) for ceramic elements and Class B (IEC751) for glass elements.
Accuracy tolerances are specified as ±(0.15 + 0.002|T|) °C for Class A and ±(0.3 + 0.005|T|) °C for Class B. All elements feature an Alpha coefficient of 0.00385.
Response times vary by model, medium, and percentage response:
- Flowing Water (V = 0.4 m/sec): 50% response ranges from 0.14 to 0.8 seconds; 90% response ranges from 0.35 to 2.4 seconds.
- Moving Air (V = 1 m/sec): 50% response ranges from 2.0 to 16.0 seconds; 90% response ranges from 7.0 to 40.0 seconds.
Self-heating error in flowing air (V = 1 m/sec) is documented between 0.08 and 0.39 °C/mW depending on the specific model configuration.
Configuration Options
The series offers configurable dimensions, resistance configurations, and lead options to accommodate various installation requirements.
- Nominal Resistance: 1 x 100 Ω or 2 x 100 Ω (dual element).
- Diameter: Ranges from 1.5 mm to 4.5 mm across the series.
- Insertion Length: Available in lengths of 15, 25, and 30 mm for ceramic elements; glass element dimensions vary by model code (e.g., GX0518HG, GO1020).
- Electrical Connection: Standard leads are 10 mm long. Options include standard 10 or 15 mm leads and welded insulated extension leads.
- Wetted Materials: Platinum wire with a ceramic body for the KN series; glass core and glaze for the GX/GO series.
Pricing is noted as dependent on lead style. Model numbers follow patterns such as 1PT100KNCLA, 1PT100GX, or 1PT100GO.
Key Product Differences
The series distinguishes between ceramic and glass constructions with specific performance characteristics:
- Ceramic (KN Series): Designed for high-temperature stability and shock resistance. These elements are Class A compliant per IEC751.
- Glass (GX/GO Series): Offered in various dimensional configurations with good vibration resistance depending on the mounting method. These elements are Class B compliant per IEC751.
Dual-element versions are available, indicated by a leading '2' in model numbers such as 2PT100KN3045CLA or 2PT100GO4530-B. Specific glass models like the 1PT100GX0518HG support an extended upper temperature limit of 450°C compared to the standard -220 to 400°C range for other glass variants.
