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
