The high-temperature pressure transmitter uses high-precision and high stability high-temperature pressure sensor components. It is a pressure sensor that uses a high-temperature resistant pressure core or sapphire core as the measuring material. Through a highly reliable amplification circuit and precise temperature compensation, it converts the absolute pressure or gauge pressure of the measured medium into standard electrical signals such as 4-20mA, 0-5VDC, 0-10VDC, and 1-5VDC. High quality sensors, fully sealed welding packaging technology, and sophisticated assembly processes ensure the excellent quality and performance of this product. This product has multiple interface forms and lead methods, which can meet the needs of customers and is suitable for use in high-temperature industrial environments with various measurement and control equipment. It is also widely used in industry, collecting pressure signals at pressure measurement points in pipelines of some high-temperature steam and high-temperature fluids.
◆ Overview
The TM-DBS208 and 308 series pressure transmitters (diffusion silicon pressure transmitters) have advantages such as reliable operation, stable performance, easy installation and use, small size, light weight, and high cost-effectiveness. They can be widely used in various positive and negative pressure measurements. The pressure transmitter adopts imported diffused silicon or
The ceramic core serves as a pressure detection element, and the sensor signal is converted into a unified output signal of 0-10mA or 4-20mA through a high-performance electronic amplifier. Pressure transmitters can replace traditional remote pressure gauges, Hall elements, differential transmitters, and have the performance of DDZ-II and DDZ-III transmitters. Pressure transmitters can be used in conjunction with various types of dynamic coil indicators, digital pressure gauges, and electronic potentiometers. Pressure transmitters can also be used in conjunction with various automatic control systems or computer systems.
