Hot runner coil heater for precision heating systems with different sleeves
Description:
Thermocouples are manufactured in many different configurations for multitude of applications.Diameters,lengths,sheath material,lead material,lead lengths and sensor material are just a few of the variable that go into determining the style of thermocouple when manufactured.The main determining factors of what type thermocouple needs to be used in a application is temperature, environment response time and accuracy.The junction of the thermocuple can be grounded,ungrounded or exposed.The lead length may vary depending on the distance of the temperature controller from the thermocouple sensor.The metal that the sensor is constructed by determines the type of thermocouple manufactured.
1) Spring coil heater is made of nickel chrome resistance wire placed inside chrome nickel steel tube that is filled with MgO powder.
2) Spring coil heater is also known as high performance tubular heaters or cable heaters.
3) Spring heater can be produced with or without built in thermocouples.
4) Spring coil heater is widely used in heating engineering, mold, plastic industry, including the transfer machinery, medical equipment, casting process, welding, heat treatment process and many other industries and fields
