Specification
Shockproof Pressure Gauge NT53D
Product Overview
The Shockproof Pressure Gauge NT53D is a liquid-filled mechanical pressure gauge designed for stable and accurate pressure measurement in industrial environments with vibration, shock, and fluctuating operating conditions.
The gauge adopts a fully liquid-filled construction, effectively reducing pointer vibration and improving reading stability. Its waterproof, shock-resistant, and sealed design ensures reliable long-term operation while extending the service life of internal components.
Manufactured with durable stainless steel housing and high-quality copper alloy internal components, the NT53D is suitable for measuring the pressure of non-corrosive media, including oil, water, and air, especially in applications with continuous mechanical vibration.
Operating Principle
The Shockproof Pressure Gauge NT53D utilizes a Bourdon tube (Baden tube) sensing element to convert system pressure into mechanical movement.
As pressure enters the Bourdon tube, the tube elastically deforms. This movement is transmitted through the internal mechanical linkage to drive the pointer across the dial, providing a direct pressure indication.
The liquid-filled housing dampens pointer oscillation caused by vibration and pressure pulsation, resulting in more stable readings and improved long-term measurement accuracy.
