The HPTM280 protective temperature-pressure integrated transmitter uses a diffused silicon piezoresistive pressure sensor with high stability and reliability, as well as a PT100 for measuring signals. Through an automatic testing and laser resistance adjustment process, it can compensate for performance at a wide temperature range and simultaneously obtain liquid level and temperature signals.
The product has undergone strict screening in the form of long-term ageing and stability assessments, ensuring stable and reliable performance. It can be used in situations where the working environment is poor and pressure needs to be displayed on site. It is widely used for pressure measurement in mechanical, metallurgical, petrochemical and electric power processes, among others.
