Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.
The digital pressure gauge produced by Jinli Automation Instrument Co., Ltd. has high precision, high stability, error ≤1%, internal power supply, micro power consumption, stainless steel casing, strong protection, beautiful and delicate features. It is a common measuring instrument and is widely used in various fields. It visually displays pressure changes at various process stages, provides insight into the formation of conditions in a product or media process, monitors safety movements during production runs, and passes automated interlocking or sensing devices. Digital pressure gauges should pay attention to the following during use:
1. The general verification period of the digital pressure gauge is half a year. Mandatory verification is a legal measure to ensure the reliable performance of the digital pressure gauge, the accurate transmission of the quantity and the effective guarantee of safe production.
2. The pressure range of the digital pressure gauge should not exceed 60 to 70% of the scale limit.
3. If the medium used for measuring the digital pressure gauge is corrosive, then it is necessary to select different elastic component materials according to the specific temperature and concentration parameters of the corrosive medium, otherwise the intended purpose will not be achieved.
4. The accuracy of the digital pressure gauge for work is expressed as a percentage of the allowable error to the limit value of the dial scale. The accuracy grade is generally marked on the dial. When using a digital pressure gauge, the accuracy should be determined according to the pressure level of the equipment and the actual work needs.
5. Diameter of the dial In order to enable the operator to accurately see the pressure value, the dial diameter of the digital pressure gauge should not be too small. If the digital pressure gauge is installed higher or farther away from the post, the diameter of the dial should be increased.
6. Daily attention to the use of maintenance, regular inspections, cleaning and record the use of the situation.
The digital display pressure gauge can work as usual in a vibrating environment for a long time, and the display is intuitive without causing visual errors; however, conventional electric contact pressure gauges cannot do this.
