Murphy EGS21 P-300-24-B is an electromechanical relay instrument designed for pressure measurement.
It has a measurement range of 300 psi (2.07 MPa / 20.70 bar) and is powered by a 24V DC system with a built-in step-down resistor. The instrument features an SAE-type low-treated stainless steel bezel and an impact-resistant, waterproof polyester (PBT) housing, with the mirror surface having UV protection.
It utilizes a Hall-effect sensing element, outputs ground signals, and triggers in a decreasing manner. The trigger adjustment range is adjustable within 90% of the dial, widely used in various industrial scenarios to effectively monitor pressure changes and provide reliable protection for stable system operation.
