The HPTM280 protective temperature and pressure integrated transmitter adopts a highly stable and reliable diffusion silicon piezoresistive pressure sensor and PT100 as the signal measurement element. It has undergone automatic testing and laser resistance adjustment process for wide temperature range performance compensation, and can simultaneously obtain two signals of liquid level and temperature. The product has undergone strict screening processes such as long-term aging and stability assessment, and its performance is stable and reliable. This product can be equipped with on-site digital display and is suitable for applications in harsh working environments that require on-site display of the measured pressure. It is widely used for pressure measurement in industrial processes such as machinery, metallurgy, petrochemicals, and power.
