Industrial Cartridge Heater With Internal Thermocouple
Industrial Cartridge Heater With Internal Thermocouple use metal tube as a sheath (including stainless steel, copper tube), which utilize resistance wiring close to the heater sheath for heating transfer ,isolated by a thin layer of compacted MgO insulation.
For this Industrial Cartridge Heater With Internal Thermocouple can also specify lead length and choose from a variety of lead options. Leads can be insulated with fiberglass or PTFE or protected by stainless steel braid or hose.
Industrial Cartridge Heater With Internal Thermocouple also have an option many others lack: the ability to have an internal J or K-type thermocouple located near the tip of the heater.
The lead type:
Swaged in lead type:
Terminal type:
1. Sheath Material : Selection of German imports of high temperature precision stainless steel tube,Wall thickness uniform, fine workmanship, good physical properties.
2. Resistance wire: US imports of nickel-chromium alloy heating wire,High elongation, accurate resistivity, good physical properties.
3. MgO stick: 99.9% high purity magnesium oxide stick, good verticality, small tolerance
4. MgO: 99.9% pure magnesium powder, high purity, good particle size ratio, resistant to 1200 degrees
5. Lead: High temperature pure nickel glass wire, resistivity, high conductivity, resistance to high temperature of 800 degrees.
