Temperature Sensors Several common fault resolutions At present, more and more temperature sensors are used in different fields, and such problems will inevitably occur during use. In general, the temperature sensor failure is rare. As long as it is carefully tested at the factory, these conditions can be avoided. Therefore, the temperature sensor should be inspected at the factory, and the customer can also find the sensor manufacturer. Ask for a factory inspection report for reference. Temperature sensor technology is very mature, and it is very common in various factories. Temperature sensors are often used with some instruments, and there are often some small faults in the matching process. Therefore, here are a few common faults and solutions after encountering a fault: First, the transmitter output does not change when the temperature of the measured medium rises or falls. This is mostly a problem of temperature sensor sealing. It may be because the temperature sensor is not sealed or the sensor is accidentally soldered during soldering. A small hole, this situation generally needs to be replaced by a sensor housing. Second, the output signal is unstable. This reason is the cause of the temperature source. The temperature source is an unstable temperature. If the meter is unstable, it is the reason that the meter's anti-interference ability is not strong. Third, the transmitter output error is large. There are many reasons for this. It may be that the temperature sensor of the selected temperature sensor is incorrect, resulting in a range error. It may also be that the sensor is not calibrated when it leaves the factory. The temperature sensor failure is rare. As long as it is carefully tested at the factory, these conditions can be avoided. Therefore, the temperature sensor should be inspected at the factory, and the customer can also ask the sensor manufacturer for the factory inspection report. For reference. Iron-based alloy powder is commonly used in plasma transfer arc welding (PTAW) due to its excellent mechanical properties and high resistance to corrosion and heat. This type of powder is typically composed of iron as the base metal, along with various alloying elements such as nickel, chromium, molybdenum, and tungsten.

The specific composition of the iron-based alloy powder may vary depending on the desired properties and application requirements. For example, adding nickel can increase the strength and toughness of the weld, while chromium enhances the corrosion resistance. Molybdenum and tungsten are often added to improve the high-temperature strength and creep resistance of the weld.
Iron-based alloy powders for PTAW are available in various particle sizes, typically ranging from a few micrometers to several hundred micrometers. The powder is usually fed into the plasma arc through a powder feeder, which ensures a controlled and consistent supply of powder during the welding process.
During PTAW, the powder is melted and deposited onto the workpiece, forming a weld bead. The high energy plasma arc provides the heat necessary to melt the powder and the base metal, creating a strong and durable weld joint.
Overall, iron-based alloy powder for plasma transfer arc welding offers excellent weldability, high mechanical properties, and resistance to corrosion and heat, making it suitable for a wide range of applications in industries such as aerospace, automotive, and power generation.
