The automatic temperature limiting function of the self-limiting electric tapes can ensure that the sampling tube maintains a certain constant temperature, ensuring that the collected sample remains basically the same as the initial value, ultimately ensuring the aforementioned three systems to continuously and correctly collect the sample gas. According to the composition of the collected sample gas, temperature and other actual conditions, sampling tube can be used in different materials, electric tapes can be selected according to user selection of high, medium and low temperature products, in addition, according to the function of the configuration of a variety of wires, etc..
Anti-corrosion sampling with heat composite tube is a combination of a variety of devices set a variety of functions in one composite body: the
Sampling: a variety of types and materials of sampling tubes can be combined.
Heat tracing: self-regulating power, automatic compensation, heat tracing and heat preservation, efficient adiabatic.
Electrical control: can be equipped with instrumentation signal cable, compensation cable and control cable to meet the instrumentation display monitoring, for the computer centralised control to create conditions; safety fire, leakage protection, anti-static, electromagnetic shielding role.
