Explosion-proof electrical contacts YTXC-100/150-B used Ordering Information: 1, the instrument should be installed in the environment -20 ℃ ~ 40 ℃ YN-100 pressure gauge manufacturer, relative humidity less than 80%, lower than the altitude 2000m, installed by the location, the monthly average temperature is not higher than + 30 ℃, due to changes in temperature YN-100 pressure gauge, allowing the surface to produce Cream gauge, measured medium temperature <70 ℃, (if used for steam other high-temperature dielectric measurements, temperature should be used in explosion-proof electrical contacts). 2, the instrument must be mounted vertically, and strive to maintain the same level position with the measuring point, or should be included in the additional error caused by the level difference. 3, instrument electrical lines (see figures 2) YN-100 pressure gauge sales, carefully checked and properly followed the action on the test. 4, some of the general use of pressure gauge pressure cap 3/4. 5, when adjusting the meter setpoint (by adjusting the knob, the upper and lower limit set value pointer adjusted) should adjust the lower limit set value and then adjust the upper limit set value. 6. Open the outlet box or the need to adjust to after power off when setpoint range. 7, measuring corrosive, crystallization and solidification of the medium, requires the use of acid-resistant, corrosion-proof electrical contacts or diaphragm, measuring small pressure (10Kpa ~ 60Kpa), with diaphragm-proof electrical contacts, there is vibration measurement occasions please use the magnetic-assisted electrical contacts or explosion-proof electrical contacts using digital pressure gauge diaphragm structure principle when measuring the role of the media pressure P diaphragm, the diaphragm produce deformed compression pressure sealing liquid form only manometry system, it P- △ P formation pressure. When the diaphragm is rigid enough, then △ P is small, the pressure pressure gauge pressure measurement system for measuring the dielectric formed nearby table due to the diaphragm seal system consists of filling the liquid as the delivery pressure of the media, since the sealing temperature of volume expansion factor, the pressure meter with pressure and temperature indication Department also increased its volume and temperature coefficient of expansion of the liquid seal diaphragm stiffness and pressure-receiving portion temperature. Especially for low-range pressure gauge, the effect is more pronounced. General provisions of the pressure receiving portion temperature error of not more than 0.1% / ℃. Therefore, the overall impact of the diaphragm pressure gauge temperature is normally provided by general-purpose instrumentation and temperature affect the amount of pressure on the diaphragm assembly unit temperatures affect the amount of the sum of both.
