Temperature Sensors - NTC Thermistors NTC thermistors are temperature sensors that use fluctuating electrical resistance to measure temperature. The resistance of an NTC thermistor decreases as the temperature around it increases, making it possible to measure the amount of heat or cold in the environment. One of the most common applications for NTC thermistors is in vehicle air conditioning systems, where the interior temperature of the vehicle is measured by the thermistor and the air conditioning system is adjusted accordingly. The 129-202VME-S01 is a type of NTC thermistor designed specifically for measuring engine coolant temperature in commercial vehicles. The thermistor measures the temperature of the coolant as it is circulated throughout the engine block, and is able to record temperatures up to 250°F (121°C). The VME-S01 uses a 2-wire circuit and works by employing a 15K Ohm pull-down resistor to provide a consistent voltage to the thermistor. As the temperature of the coolant rises, the resistance of the thermistor also increases, resulting in a drop in the total voltage on the circuit. To ensure a more accurate reading of temperature, the 129-202VME-S01 is constructed from materials that are highly sensitive to changes in temperature. The ceramic-encased thermistor is constructed from a specially formulated mix of metal oxides, and its electrical resistance is temperature sensitive over a range of -55°C to 180°C. The VME-S01 thermistor is also highly durable as it has a long life expectancy and is resistant to shock and vibration.The 129-202VME-S01 is an ideal choice for applications requiring precise temperature measurement, such as monitoring coolant temperature in commercial vehicles. It is a reliable and cost-effective solution that offers a wide temperature range (-55°C to 180°C) and is easy to install and configure. The thermistor’s high accuracy, long life expectancy, and versatility make it a useful tool in a variety of temperature monitoring applications. NTC thermistors are also used for temperature regulation in domestic and commercial heating systems. In such applications, the thermistor is used to provide a switching mechanism for a thermostat, which can be adjusted to maintain a preferred temperature range. The thermistor senses temperature changes and automatically adjusts the current flowing through the heating element to ensure the temperature remains within the desired range.Overall, the 129-202VME-S01 is a one of the most popular types of NTC thermistors available, and is widely used in automotive and other applications due its reliability, accuracy and cost-effectiveness. The thermistor is easy to install, offers a wide range of applications, and can be used in both commercial and domestic environments. As such, it is an ideal choice for those looking for a reliable and accurate temperature sensing solution.
