. . Domestically produced, fully waterproof digital pressure gauge with no zero drift for long-distance measurement; the pig took a few photos of them for a beauty contest yesterday. . . . . . :Lol, whether it’s beautiful or not depends on the thighs… Feel free to vote! It’s completely waterproof – in other words, it welcomes being exposed to rain and water; does she want a Valentine’s Day that’s soaked in water? There’s no drift at all – it will fall in love with you and stick to you, without any infidelity or instability
. . She, with her charming eyes – a LCD screen with white background and black text; the backlight is bright white. It’s bright during the day, and it remains bright even at night. She doesn’t care about darkness or lightness, she just wants to hook up with a handsome guy ~~~~~~~~~~ :lol. .
Remote digital pressure gauges…… I guess you’re the only place where you can find such things. . .
Excuse me, for this digital pressure gauge mentioned by the poster, if it doesn’t have remote transmission functionality, does it require power? What is its working principle? I’d like to know more about it. Thank you
. . Calling it an intelligent digital display pressure transmitter is also fine. . . . . . But due to her face, as well as the various pressure conversion ratios and the lack of a glass cover, it seems more appropriate to classify her as part of the pressure gauge family. . . . . . In the picture above, the one with the Ex mark and a jujube-red panel is of the intrinsically safe explosion-proof type, while the other 6 are of the regular type.
. . It doesn’t use glue; waterproofing is achieved through the sealing ring. . . When using glue for sealing, once there’s a problem with the gauge, it can no longer be repaired. For pressure gauges, using glue for sealing isn’t a good approach. The probe of such gauges can be installed facing downward, upward, to the left, to the right, or at any angle. Why is that? That’s because its dial can rotate 360°; in other words, no matter what direction the probe is pointed, the dial can be adjusted so that the pressure reading can be viewed easily. To do this, loosen the screw on the case used to secure the dial, then rotate the dial. Once it’s adjusted, tighten the screw again so that the dial doesn’t come loose due to vibrations. .
. . 1. Any digital gauge requires a power supply, either from an external source or from an internal battery. 2. Its output signal is 4–20mA; it can be referred to as a remote digital pressure gauge or an intelligent pressure transmitter. In other words, it consists of the following components: a pressure sensor, an operational amplifier, an analog-to-digital converter, a microcomputer, a digital-to-analog converter, and power supply elements. .
The design of sealing rings must be quite sophisticated to achieve that, right?
. . A pressure gauge, well, it doesn’t fetch much money either – how complex can it be? :Lol, it’s so simple to use a sealing ring – for example, buy a watch, take it apart to check its dimensions, think about how it works, and then imitate that process, and you’ll learn how to do it. Speaking of the difficulties, the buttons on the waterproof panel of this watch are indeed a challenge – even if it’s placed in a basin of water for several days, no water gets inside the casing {:3_51:}. .
I’d be very grateful if you could provide some detailed diagrams of the structure, such as the buttons or how to remove the casing. Hehe
