Radio Frequency

Detail Watlow’s TR thermocouple probe is designed for use in plasma generation applications to ensure accurate temperature readings through radio or conduction environments where traditional sensors are ineffective. Radio frequency energy can cause serious temperature measurement errors when exposed to these types of environments.
Features & Benefits 3000VDC dielectric rating allows thermocouple to be used in platens with dc bias
  High thermal conductivity design ensures accurate, repeatable measurements
  High CMMR lead wire design reduces induced error from EMI
