industrial useProduct Details
Differential pressure transmitter. Made of stainless steel, it can accurately measure industrial parameters such as differential pressure, pressure and liquid level. With stable performance and strong anti-interference, it is widely used in petroleum, chemical, power and other industries, serving as a core instrument for industrial automation measurement and control.
