Overview: The document provides comprehensive details on standard cartridge
heaters, focusing on specifications, manufacturing standards, and available configurations. It emphasizes the adaptability of these heaters with built-in thermocouples and various connection types.
Specifications: - Cartridge heaters can include built-in 'J' thermocouples, with standard connection leads and thermocouple wires measuring 1000 mm.
- Available diameters range from 6.35 mm (1/4'') to 25.4 mm (1'').
- Length tolerances are ±2 mm for lengths under 100 mm and ±2% for lengths 100 mm or more.
- Rated wattage ranges from 75 to 2500 W, with a maximum watt density of 50 W/cm² under specific conditions.
- Rated voltage is 230 V single phase.
- Heaters are manufactured with a stainless steel sheath and ceramic end cap for lead protection.
- Compliance with EN 60335-1 standards is noted, with a wattage tolerance of +5% to -10% and leakage current under 0.5 mA/kW.
Manufacturing and Stock: - Heaters are produced using high-density technology requiring an H7 bore fit.
- Stocked heaters are available within 48 hours, subject to stock limits.
- Special manufacturing options include odd sizes, variable power zones, and built-in thermocouples.
Connection and Accessories: - Multiple connection types and accessories are available, detailed on pages 9 and 12.
Dimensional Tolerances: - Diameter tolerances range from -0.03 mm to -0.16 mm depending on the size.
- Minimum and maximum lengths are specified for each diameter, with some requiring consultation for maximum lengths.
Important Notes: - Specifications are subject to change without notice due to technical evolution.
Procedures: Recommendations for assembly include ensuring a proper fit with an H7 bore tolerance to facilitate heat transfer. The use of thermal transfer paste, such as GRIPACIM, is advised to enhance heat conduction, but caution is advised to avoid applying paste over connection wires.
Standards and Safety: The document highlights the absence of an earth wire in standard heaters, placing the responsibility on users to comply with local safety standards. It advises protecting connections from excessive bending and moisture exposure.
Recommendations: For applications requiring high watt density or temperature, tighter fitting tolerances are suggested. The document advises against operating cartridge heaters in open air and recommends consulting the technical assembly section for detailed guidance.
Additional Information: The document mentions the availability of specific accessories and connection types, as well as a special product range for non-standard applications.
