随着通讯设备技术的不断进步，对交换和用户设备的保护要求也大大提高了。用PTC热敏电阻器保护电话线路，主要针对以下原因引起的过电流现象：直接雷击或者邻近电话线路设备的雷击引起的浪涌电流；邻近的电力线路或者铁路系统故障时引起的交流感应电压；电话线路与电力线路搭接；通常每一条电话线都串联一个PTC热敏电阻，参即使有初级保护（通常是一个气体放电管），PTC热敏电阻也必须满足严格的要求。由于会出现高达2千伏的电压脉冲，为了耐受短期的感应电压，PTC热敏电阻必须有高耐压能力。如果线路中有初级保护，PTC热敏电阻耐压200V~300V就足够了，线路中没有初级保护，PTC热敏电阻耐压必须在600V以上。AMPRON公司能生产一系列满足上述要求的PTC热敏电阻器。

当电路处于正常状态时，通过PTC的电流小于额定电流，PTC处于常态，阻值很小，不会影响被保护电路的正常工作。当电路出现故障，电流大大超过额定电流时，PTC陡然发热，呈高阻态，使电路处于相对"断开"状态，从而保护电路不受破坏。当故障排除后，PTC亦自动回复至低阻态，电路恢复正常工作。选用PTC热敏电阻器作为过载保护元件，首先确认线路最大正常工作电流（就是PTC热敏电阻器的不动作电流）和PTC热敏电阻器安装位置（正常工作时）最高环境温度、其次是保护电流（就是PTC热敏电阻器的动作电流）、最大工作电压、额定零功率电阻，同时也应考虑元件的外形尺寸等因素。

Pressure Sensor and Temperature Sensor used in Hemodialysis Treatment

2013 - 12 - 11

As it is known, Hemodialysis is currently the most efficient way to treat patient of acute or chronic Kidney failure. The machine works as human kidney to take blood out of the body, exchange substances in the dialyzer through extracorporeal circulation, remove metabolic waste and excess water, and then return to the body through the vein.The treating process cannot be interrupted and it must be ensured that the indicators in the dialysis operation are in normal stage in order to guarantee the clinical treatment. Various sensors, including pressure sensors, temperature...

Pressure Sensor for Air Conditioner

ACCP Series Ceramic Capacitor Pressure Sensor is created by Ampron using ceramic material under special procedure. Ceramic is a recognized material that is highly elastic, resistant to corrosion, abrasion, shock and vibration. The thermal stability of ceramics allows it to operate over a temperature range of -40 ° C to 135 ° C with high precision and high stability. Its anti-overload capability can reach up to 100 times of the range, completely solving the shortcomings of other types of sensors with poor overload capability in a small range. Besides its range as genera...

Oxygen Sensor

2013 - 12 - 11

The oxygen sensor detects the oxygen content in the engine exhaust and sends a corresponding voltage signal to the electronic control unit (ECU) to reflect whether the air fuel mixture ratio is lean or rich. The ECU will control the amount of fuel injection amount and intake air accordingly, so that the engine operates in the optimal air fuel mixture ratio state, thereby creating ideal conditions for the exhaust gas treatment of the three-way catalyst. If the mixture is too rich, the amount of fuel must be reduced. If it is too thin, it then increases the amount of fuel. In the conve...
