High Temperature Thermocouple Probe
Despite being smaller, lighter, and easier to assemble than armored and constructed thermocouple sensors, thermocouple temperature probe sensors are capable of measuring temperatures as high as 1000 °C. The probe section’s material and design mostly determine the recorded temperature range.
Features And Application Areas Of High Temperature Thermocouple Probe:
With a shielded lead wire and a sheath diameter of Ф1.5~Φ8mm, the High Temperature Thermocouple Probe is flexible, resistant to high pressure, has a quick thermal response time, and has a long operational life. In a variety of manufacturing processes, these sheathed thermocouples may directly monitor the temperature of liquids, vapors, gaseous media, and solid surfaces.
Chemical equipment, environmental protection equipment, boiler equipment, vacuum furnaces in petrochemical, metal smelting, and other industries can all benefit from the use of High Temperature Thermocouple Probe sensors, which are typically combined with temperature controllers, paperless recorders, and signal isolators to create temperature monitoring systems.
