Switch between the temperature sensing cable and analog temperature cable
2016-05-11
Switch temperature sensor cable, also known as temperature-type temperature sensing cable, generally in the design has been fixed when the alarm temperature, and is a one-time can not be restored, that is, as long as the alarm, and switch the temperature cable has been destroyed , Must be updated cable. The analog temperature cable can be restored, but each time according to environmental changes, do on-site calibration, if the scene calibration is not good, it is easy to cause false positives. Temperature cables are charged with temperature measurement of the cable, in the dangerous area is generally not used this way.
In the dangerous area will generally use optical fiber and temperature measurement cable. These two are not charged temperature measurement, is the intrinsically safe products. Optical fiber has a domestic import, the quality difference is very large. Temperature measurement cable is also called hot detectors, there are imported domestic, the difference is greater. At present the larger amount is the temperature measurement cable, using the US imports of products, cost-effective. Mainly used in power plants, power plants, coal bunkers, terminals, oil irrigation, coal furnace, desulfurization and so on.
