What is a Pressure Gauge？
There are many types of pressure gauges, not only general (ordinary) pointer type, but also digital type; not only conventional type, but also special type; not only contact type, but also remote transmission type; not only vibration resistance type, but also earthquake resistance Type; not only diaphragm type, but also corrosion-resistant type.
The pressure gauge series is complete. It has not only conventional series, but also digital series; not only ordinary medium application series, but also special medium application series; not only switch signal series but also remote transmission signal series, etc., all of them are derived from practical needs and have been formed The complete series. Pressure instruments are common measuring instruments and are widely used in various fields. It can intuitively show the pressure changes in each process link and insight into the conditions in the product or medium process. It monitors the safety trends in the production and operation process and constructs a rapid and reliable safety guarantee through automatic interlocking or sensor devices. Personal and property safety played an important role.
Pressure gauges can be found everywhere in such fields as heat pipe networks, oil and gas transmission, water supply and gas supply systems, and vehicle maintenance and repair shops. Especially in the process of industrial process control and technical measurement, due to the high mechanical strength and easy production of elastic pressure sensitive components of mechanical pressure gauges, mechanical pressure gauges have become more and more widely used.
From the perspective of the installation structure type, there are direct installation, flush-mounted and convex mounting, of which the flush-mounted type is divided into radial flush-type and axial flush-type, and convex-type also has radial convex-type and axial Convex mounted points. Direct mounting type is divided into radial direct mounting type and axial direct mounting type. Among them, the radial direct installation type is the basic installation type. Generally, when the installation structure type is not specified, it refers to the radial direct installation type. The axial direct installation type considers the stability of its own support. Generally, it is only used on pressure gauges with a nominal diameter of less than 150mm. The so-called built-in and convex-type pressure gauges are the pressure gauges with edge (mounting ring) we often say. Axial flush-type both axial front band edge, radial flush-type means radial front band edge, radial convex mount type (also called wall-mounted type) refers to radial rear band edge pressure gauge.
From the measurement range and range sections, the positive pressure range is divided into a micro-pressure range section, a low-pressure range section, a medium-pressure range section, a high-pressure range section, and an ultra-high-pressure range section. It also subdivides several measurement ranges (meter range); in the negative pressure range (vacuum), there are 3 types of negative pressure (vacuum gauge); the pressure gauge of the combination of positive pressure and negative pressure is a kind of pressure across the range table. Its standard name is pressure vacuum gauge, also called vacuum pressure gauge. It can measure not only positive pressure but also negative pressure.
Let’s get to know the different types of pressure gauges:
Ordinary pressure gauge
Ordinary pressure gauges are local pressure gauges, which show the pressure on the spot without remote transmission display and adjustment function.
Digital electric node pressure gauge
Digital pressure gauge is also known as a digital pressure controller or digital pressure relay. It has settings and control functions. The upper and lower limit intervals can be set within a small interval. The alarm can be set with a delay. It is a precise quantity. Digital pressure gauge is the instrument of choice for precision measurement control
Pressure vacuum gauge
Meters based on atmospheric pressure for measuring pressures greater and less than atmospheric pressure..
Vacuum pressure gauge
Vacuum pressure gauges are based on atmospheric pressure and are used to measure instruments that are less than atmospheric pressure.
Measuring gas pressure
Memory pressure gauge
Compared with other pressure gauges, the memory pressure gauge has one more memory device. It can record the measured values for easy observation.
Diaphragm pressure gauge
Diaphragm pressure gauge is suitable for measuring the medium pressure of strong corrosion, high temperature, high viscosity, easy to crystallize, easy to solidify, solid floating matter, and to avoid the measurement medium directly entering the universal pressure instrument and preventing the accumulation of sediment and easy cleaning.
High static pressure differential pressure gauge
Differential pressure measurement of high static pressure differential pressure gauges in petrochemical, electric power and other enterprises, mainly used for centrifugation
Machine, compressor lubrication system and filter differential pressure measurement and other key systems.
Electric node pressure gauge
The pointer and the setting pin of the pressure gauge are respectively equipped with contacts. When using the upper and lower limit set values, the contacts on the pointer are connected with the contacts on the upper and lower setting pins. Alarm signal from indicator light.
Precision pressure gauge
The pressure measuring elastic element of the precision pressure gauge is processed by a special process, which makes the performance of the precision pressure gauge stable and reliable. After the debugging with the high-precision transmission mechanism, it can ensure accurate indication accuracy. The precision pressure gauge is provided with a mirror ring (A type and B type) under the scale line, which makes the reading more clear and accurate in use.
