Product overview
The TTR sheathed thermocouple is of short thermal response time, dynamic error reduced, large measurement scope, high mechanical strength and good pressure-resistant properties. It has many advantages (such as being bent, resistance to high pressure, quick thermal response time and being sturdy and durable). Like industrial fabricated thermocouple, it, as the sensor for temperature measurement, is usually used in conjunction with display instrument, recording instrument and electronic regulator and can be also used as temperature-sensing element of fabricated thermocouple. It can be used to directly measure the temperature of liquid, steam and gas medium and solid surface within the scope of 0℃～1300℃ in all kinds of production processes.
