TDK Introduces new temperature and pressure sensors
Modern industrial automation control increases the accuracy requirements, and the temperature sensor's operating temperature range, accuracy, and reliability requirements are also increasing. TDK has introduced a series of new products to meet market requirements. To monitor the control modules of the equipment and the various parameters of the surrounding environment, the most basic temperature and pressure monitoring will become a common trend. For example, temperature monitoring of the main chip, IGBT, MOSFET, and diode can prevent the continuous rise of the operating temperature during continuous operation and cause the failure of the main core electronic components. As the most cost-effective temperature protection component, NTC thermistor can continuously provide peripheral temperature data monitoring. When the temperature reaches the critical point set by the control module, the protection system of the device is activated to reduce the temperature of the device. In industrial equipment applications, power modules and various control boards use this mode. Pressure sensors have also become indispensable key components in industrial automation, such as monitoring the pressure of gases and fluids in the operation of the equipment to promote smoother operation of the equipment.
The S860 series from EPCOS is based on ceramic chip technology and process. The temperature deviation is 2 °C at 120 °C, which is suitable for IGBT chip packaging. Encapsulating the thermistor temperature sensor in the IGBT ensures that the IGBT module operates normally under the highest power conditions.
Another M703 series, which operates from -55 ° C to 150 ° C, can meet the requirements of the double 85. This series of products is suitable for photovoltaic inverters and industrial control modules, and is also very suitable for OBC/DC-DC modules in new energy vehicles.
The application of high-temperature new materials, heating systems and nozzle temperatures in excess of 300 ° C, conventional ordinary sensors are difficult to meet the use of spare parts. Now TDK has introduced a temperature sensor with a maximum operating temperature of 650 ° C, which can adapt to a variety of extreme applications, such as the automotive industry, the aerospace industry.
In the pressure sensor, the pressure control of the fluid causes the medium to contact the chip. To better protect the chip, TDK introduces a miniature oil-filled pressure sensor MiniCELL, which uses a stainless steel diaphragm to encapsulate the pressure chip to prevent the corrosive medium from invading the chip. .
Ordinary pressure chips are fixed on the pedestal by glue. However, due to the different glue types selected by different customers and the material of the pedestal itself, the use and measurement accuracy of the chip will be affected. In order to solve such problems, TDK introduced the gold plating on the back of the chip and the gold plating of the pad. The user can directly fix the pressure chip by means of mounting, which is convenient for the customer to install and use.
