Medium-Isolated Pressure Sensor

MPM281Pro is a medium isolation pressure sensor with high accuracy. It uses a highly stable diffusion silicon chip and is housed in a 316L stainless steel structure with a diameter of Ф19mm. This product is also equipped with an external laser trimming compensation board, which can accurate adjust the temperature error and zero output. Besides, the gain resistance can be fine-tuned to achieve a ne tFS output signal of 3.012V ±1%.
The product is widely used in applications where pressure measurement is critical. In these applications, it is able to deliver excellent performance and stability to meet the high demands of customers.
