Temperature Sensors - NTC Thermistors are used when precise temperature measurement is required. These sensors provide accurate and dependable readings in a wide range of operating conditions. The 1DA101K temperature sensor is no exception, providing a reliable means of measurement in the harsh environment of factory equipment, outdoor instrumentation, automotive, and medical applications. The sensor is a near-linear semiconductor thermistor which contains proprietary metallic fillers to reduce both sensitivity and thermal response nonlinearity.

NTC Thermistors are typically composed of two main components: a positive temperature coefficient (PTC) element and a negative temperature coefficient (NTC) element, connected in series. The PTC element contains a polycrystalline material with a high temperature coefficient, and the NTC element contains a semiconductor material with a low temperature coefficient. As the temperature rises, the resistance of the NTC element increases, while the resistance of the PTC element decreases.

The 1DA101K temperature sensor has a resistance range of 10 ohms to over 100,000,000 ohms at 25 °C. The 1DA101K also features a robust temperature response range from -55 °C to +200 °C. It is also rated to resist pressures of up to 20 bar, adding to its versatility. Its accuracy is also superb, with a tolerance of ±0.5 °C and a capability to withstand overloads of up to 200%. The 1DA101K also has a high temperature coefficient, allowing it to cover more temperature range than most thermistors.

The 1DA101K utilizes a Wheatstone bridge circuit to measure the resistance of the sensor. This circuit comprises of four resistors connected in series with the thermistor placed in the middle. When a voltage is applied across the resistor network, a voltage gradient is generated. This voltage gradient is a measure of the difference in resistance between the two ends of the bridge. By measuring the voltage across the network, the resistance of the thermistor can be determined.

The Wheatstone bridge cross-reference system also allows for any potential drift in the resistance of the thermistor to be calibrated out by allowing for external scaling. This ensures the accuracy and stability of the measurements over time, even in fluctuating temperatures. It also aids in manufacturability, which is beneficial in applications where large number of sensors are needed.

The 1DA101K is a reliable and dependable temperature sensor, capable of providing accurate readings in a wide variety of scenarios. Its robust design and high temperature coefficient make it a sound choice for a range of temperature measurement applications. Its use of a Wheatstone bridge circuit, along with external scaling, allows for improved accuracy and stability, making it a great option for any temperature measurement need.
