449603-3

The 449603-3 is a pressure gauge, often referred to as an ‘absolute pressure’ gauge. It is used in a range of different industries that require gauges to measure absolute atmospheric pressure. It is designed specifically for measuring low and medium vacuum, as well as slightly higher gauge pressures. The gauge functions by measuring the force that is created when a gas or a liquid moves in a container, and then converting this force into an absolute pressure value.

Applications for the 449603-3 are vast, but most typically, it is used in these areas:

• In industrial manufacturing processes that include vacuum pressure environments, for example, vacuum-drying and annealing.
• For the analysis, measurement, and maintenance of HVAC systems, boilers and process piping.
• In medical settings for monitoring patient blood pressure, and the calibration of medical equipment.
• In food production and production lines, for a range of applications involving vacuum processes.

The working principle of the 449603-3 is based on Pascal’s law, or more accurately, the Bernoulli effect. This is a phenomenon where a falling pressure is produced when a liquid or gas is forced through a narrow pipe at an increasing speed. This creates a differential pressure. The 449603-3 uses a diaphragm that is sensitive the pressure and is connected to a Bourdon tube. This tube is flexible and when pressure is applied, its curved shape changes and a pointer shows the pressure reading on a dial.

The 449603-3 is manufactured to precise standards and is designed to be easy to install and easy to use. It comes pre-calibrated so that no extra calibration is needed. It can also withstand wide environmental temperature ranges, making it suitable for many applications and industrial environments. It is a reliable and accurate industrial gauge that can measure a wide range of pressures.
