Under pressure *,LABOM Bourdon tube pressure gaugeThe active contact of the relay is connected to the lower limit contact, and the relay acts and locks. Its normally open contact is closed and driven, and the motor is powered on to operate. When the pressure reaches the upper limit, the movable contact is connected to the upper limit contact, the relay acts, its normally closed contact is disconnected, the power supply is cut off, its normally open point is disconnected, and the motor stops running. Suitable for situations where the pressure of the tested substance has strong pulse changes or pressure pulse impacts, as well as places with large environmental vibrations. The instrument can measure the average pulsating pressure of gases and liquids to overcome the damage caused by strong medium pulses and environmental vibrations, ensuring the accuracy of readings. The overload capacity can reach 1-5 times the rated range. Due to the use of ceramic thick film technology sensors, even in corrosive and strong vibration environments, the transmitter can work normally with minimal impact on measurement accuracy.
Measure the positive, negative, or positive/negative pressure of liquid, gas, or other fluid media that are at high temperatures or have no corrosive effect on stainless steel. Fill the shell with low viscosity damping fluid toLABOM Bourdon tube pressure gaugeCapable of resisting working environment vibration and medium pressure pulsation, and can work normally under vibration conditions with an amplitude of ± 1mm and a frequency less than 13HZ. At the same time, it can work normally under swinging conditions with a deviation of ± 22 ° from the installation position. Due to the fact that the pressure gauge system is filled with sealing liquid as the medium for transmitting pressure, the temperature expansion coefficient of the sealing liquid causes the reading of the pressure instrument to increase as the temperature of the compressed part rises. The temperature effect is related to the expansion coefficient of the sealing liquid, the stiffness of the diaphragm, and the temperature of the compressed part, especially for low range pressure instruments, which have a more significant impact. The pressure gauge should be gently rotated by hand into the locked position first, and then two correct wrenches should be used. One should be fixed to the hexagonal joint of the locked position, and the other should be used to rotate the pressure gauge joint at the hexagonal position and tighten it.
