NTC Temperature Sensor on Copier for Office Automation

Time:2021-08-05 Views:958
With the development of sensors, especially temperature sensors, the rapid adoption of high-end household appliances and office automation equipment makes life and work environment more comfortable and convenient. Temperature sensor has become one of the indispensable components of home appliances and office automation equipment. Here‘s a look at the temperature sensor applied to the copier.

A NTC thermistor is used in the copier. Use a multimeter to measure the resistance of the thermistor at room temperature to several tens of kilohms. When using a cup of hot water to stick to the thermistor or use an electric soldering iron to approach it Its resistance will drop significantly (below 1KΩ), indicating that the thermistor is good; if the thermistor resistance remains unchanged or the resistance value is above 5KΩ, it means that the thermistor has deteriorated and failed. replace. This is just an ordinary test method. Our company uses a constant temperature oil tank to measure. As long as the measured resistance is within the accuracy range, the thermistor is no problem. If it exceeds the tolerance range, the thermistor will fail.

The thermistor in the copier is fixed on a metal bracket and encapsulated in a high-temperature resistant film with high-temperature silica gel. It is connected to the processing circuit of the copier through a lead wire, and its wire is connected to the metal connector and the plastic seat connector. The temperature sensor is characterized by fast response speed, high reliability, good stability, good heat resistance cycle ability and high temperature resistance. When it is installed in the fixing device of the copier, it can quickly complete the copying work.
