Guangzhou intelligent digital display pressure switch

product overview

DF-251The series intelligent digital pressure controller (digital pressure switch) adopts high-precision sensor components and is an intelligent measurement and control product that integrates pressure testing, display, control, and analog output. There are two ways to set switch point outputs, one way4-20mAAnalog output. This product has multiple interface forms, with optional AC and DC power supply, high precision, fast response, flexible use, easy debugging, intuitive display, convenient operation, safety and reliability, and can meet customer needs to the maximum extent. It is widely used in various pressure measurement and control systems.
