Overview

A pressure gauge can measure gauge pressure, absolute pressure, and differential pressure. In addition, the Vicat pressure gauge can be used not only to measure positive gauge pressure, but also to measure negative gauge pressure. The working mode of pressure gauges varies depending on the type. In industrial measurement technology, two different types of pressure gauges are used - Bourdon tube pressure gauges and diaphragm pressure gauges. These two types of pressure gauges have different functional principles and are therefore suitable for different applications. When using a Bourdon tube pressure gauge, the Bourdon tube directly transmits pressure to the pointer for measurement. There is a bend inside the shell, and the medium enters the bend and causes the Boden tube to extend. This extension is transmitted to the movement through connecting rods and sector gears, and displayed on the dial

Product Details

A pressure gauge is an instrument that measures and displays the pressure of a medium. Pressure gauges are pressure measuring instruments with elastic pressure elements, used up to millions of times in various industrial applications. According to the application area of the pressure gauge, Bourdon tubes, diaphragm elements, or bellows elements can be used as pressure elements.

Wika offers all commonly used watch case forms. For standard applications, plastic versions with copper alloy measurement systems are sufficient for neutral media such as compressed air, water, or oil. For hydraulic applications, we recommend using a sturdy and durable chrome alloy housing with glycerin filling to suppress the vibration of the measurement system and ensure good readability of the instrument. The pressure gauge model made of stainless steel is suitable for measuring pressure in corrosive, non viscous, and non crystalline substances, even in corrosive environments. The measurement system can also be coated with special materials such as PTFE, gold, Hastelloy, and many other materials. This can protect the instrument from the influence of corrosive media.

On the dial of the pressure gauge, we can always find the accuracy level indication. The accuracy level of a pressure gauge defines the allowable deviation of the displayed reading, expressed as a percentage of the full-scale value. For plastic shells, the value is 4% or 2.5%; For chromium steel or stainless steel instruments, the value is 1.6% or 1.0%. For testing instruments, the accuracy level is 0.6%, 0.25%, or even 0.1%, depending on the display range used. What does this mean in practice? The measurement range is 0 to 10 MPa, with an accuracy level of 1.0%, and the allowable deviation within the entire measurement range is 0.1 MPa.

description

This series of high-quality Bourdon tube pressure gauges is designed specifically to improve the safety of process industries.

Using high-quality stainless steel materials and sturdy design, this instrument is suitable for chemical and process industries. Not only suitable for liquid and gas media, but also for corrosive environments.

The range is 0 0.06 to 0 160MPa [0... 10 to 0 .. 20,000psi]， Ensure the measurement range required for various applications.

WIKA manufactures and certifies pressure gauges in accordance with the requirements of EN 837-1 and ASME B40.100 standards. As a safety feature, the instrument has an anti spray and pressure relief device on the back of the case. In the event of a malfunction, overvoltage can be dissipated and released from here.

The 233.50 model with a liquid filled case is suitable for high dynamic pressure loads and vibration situations.
