Movable flange thermocouple
1. Application:
Usually used in conjunction with display instruments, recorders, electronic computing, etc. Directly measures the temperature of liquids, steam, and gas media, as well as solid surfaces, within the 0°C~1300°C range in various production processes.
2. Features
· Simple assembly, easy replacement
· Spring-type temperature sensing elements with good vibration resistance;
· Large temperature measurement
range · High mechanical strength and good voltage resistance
3. Working Principle The
electrode of a thermocouple consists of two conductors made of different materials. When there is a temperature difference between the measuring and reference terminals, a thermoelectric potential is generated, and the working instrument displays the temperature value corresponding to the thermoelectric potential.
4. Main Technical Parameters
Product Standards
IEC584
IEC1515
GB/T16839-1997
JB/T5582-91
5. Room temperature insulation resistance
The thermocouple operates at an ambient temperature of 20±15°C, with relative humidity not exceeding 80%. The test voltage is 500±50V (DC). The insulation resistance between the electrode and the outer bushing is >1000Ω·m.
