On site pressure display instrument

Pressure gauge>>ZW-Y100On site pressure display instrument:

1、 Instrument Introduction:
On site pressure display instrumentIt adopts advanced low-power devices and unique software processing technology. It uses a large screen segment code wide viewing angle LCD display window, and the reading is very eye-catching and intuitive. High precision, high stability, error ≤ 1%, internal power supply, low power consumption, stainless steel shell, sturdy protection, beautiful and exquisite appearance. It adopts CMOS low-power integrated circuit and wide temperature type 18 × 9mm large field wide viewing angle LCD display, using two 1.5V alkaline batteries, which is particularly suitable for temperature or pressure measurement in places without power supply.

2、 Application scope:
On site pressure display instrumentBefore leaving the factory, the product undergoes processes such as high and low temperature aging, stress aging, and temperature compensation, ensuring accuracy even under harsh conditions of (0-500) ℃ range, one-year time, and 99% confidence probability. Widely used in metallurgy, petroleum, chemical, power, natural gas, metrology, and scientific research departments. It is an updated product of pointer type precision pressure gauge.

2. Panel: glass+inner PVC facial mask;
3. Pressure tube material: 1C18Ni9Ti.

6、 Usage and maintenance:
1. The instrument must be vertical: a wrench should be used to tighten it during installation, and the meter head should not be forcefully twisted; Collision should be avoided during transportation.
2. The instrument should be used in an ambient temperature range of -25~55 ℃. scholar
3. The vibration frequency in the working environment should be less than 25Hz, and the amplitude should not exceed 1mm.
4. The range of instrument usage should be between 1/3 and 2/3 of the upper limit.

7、 Precautions for use:
1. The ambient temperature during use is -40~70 ℃, and the relative humidity is not greater than 80%. If it deviates from the normal operating temperature by 20 ℃, it must be included in the temperature additional error.
2. When in use, it must be installed vertically, striving to be at the same level as the measuring point. If the difference is too high, it will be included in the additional error caused by the liquid column, which does not need to be considered when measuring gas. Block the explosion-proof port at the back of the watch case during installation to avoid affecting the explosion-proof performance.
3. The normal measurement range for use: under static pressure, it should not exceed 3/4 of the upper measurement limit, and under fluctuation, it should not exceed 2/3 of the upper measurement limit. Under the above two pressure conditions, the maximum pressure measured by the large pressure gauge should not be lower than 1/3 of the lower limit, and the vacuum part should be used completely when measuring vacuum.
4. If internal components become loose or malfunction during use, they should be inspected or repaired by the manufacturer.
