self-Regulating heating strip / self-limiting type heating strip / heating strip (HS)
The main features of self-Regulating (self-limiting type) heating strip is that its output power changes in accordance with the pipe changing, which is ainly used in the antifreeze and thermal insulation of various channels, container-type heat storage tank, the instrument¡¯s inner and outside. The constan temperature maximumly maintain 70 ¡À 5 ¡æ, 105 ¡À 5 ¡æ, 135 ¡À 5 ¡æ, applying to general areas, dangerous areas, corrosive areas.
Technical characteristics£º
£¨1£©The characteristic is measured under the conditions of analog pipeline with thermal insulation. With the temperature increasing, power more or less decline linearly, its slope is the amount of power when systematic temperature changed each one degree. it reflects the ability of power adjusting the temperature automatically. It should be noted that the power of heating strip is the steady-state parameters, many effected factors, so it should not simply be calculated by current multiplied voltage.
£¨2£©Maintain the temperature: heating strip band with a system, if the heat which heating strip transfers to systemequal the heat which system transfer to the environment per unit time, the temperature of the system remains unchanged.
£¨3£©The maximum surface temperature: power band can bear the impact of the external heat source lower than a certain temperature, if higher than this temperature, the power will decline slowly and accumulatedly. Therefore , heating strip had better not exceed the highest enduring temperature in the process of use.
£¨4£©The maximum surface temperature: the highest temperature a long enough heating strip can endure in sealed insulated containers and under the rated voltage is the maximum surface temperature of power band. This parameter is very important to those occasions of having explosive gases.
£¨5£©The mximum using length : heating strip can be cut at random, but only can be linked arbitraryly in the range of length ; In other words, it can not exceed the maximum length. The mximum using length is related to the rated voltage, power, wire cross-section and the lowest temperature of the environment under use. If required using length to exceed the mximum length, then it should link with the other power supply or use the medium or long-tpye of special specifications.
