Application Description of Electric Contact Pressure Gauge YX-150:
1. This electric contact pressure gauge is suitable for measuring the pressure of liquids, gases, and other media that do not corrode copper and copper alloys. The instrument is used in conjunction with corresponding electrical components such as relays and contactors to achieve automatic control and signaling (alarm) of the measured (controlled) pressure system.
2. Before installation, the instrument must be carefully checked for model, specifications, and whether the indicator pointer is at zero position. If the model does not match or the pointer deviates from zero position, the cause should be identified and replaced or rechecked.
3. The instrument should be installed in an environment where the temperature of the surrounding environment (or medium) is -40~+70 ℃, the relative humidity is not greater than 85%, and the vibration or rapid pulsation of the measured pressure has no impact on the reliable operation and correct reading of the docking point.
4. The instrument should be installed vertically and strive to maintain the same horizontal position as the pressure measuring point. Otherwise, additional errors caused by liquid level differences must be included accordingly.
After the electrical circuit of the instrument is set up and connected properly, it should be carefully inspected and tested before being put into use.
When adjusting the set value of the instrument, the key (attachment) should be used.
When measuring stable pressure, the instrument can be used within the range of 1/3 to 2/3 of its upper limit of scale; When measuring alternating pressure, it is advisable to not exceed 1/2 of the upper limit of the scale; For instantaneous measurements, it is allowed to use up to 3/4 of the upper limit of the scale, but this restriction is not applicable when measuring negative pressure (i.e. vacuum).
During use, the instrument should be kept dry and clean regularly, and properly maintained.
9. Under normal use, instruments should be inspected regularly, generally every three months. If the instrument suddenly malfunctions (due to leakage or rupture of the spring tube causing pressure relief, contact melting or severe oxidation affecting the reliability of contact, pointer detachment, looseness or indication distortion, etc.), it must be repaired immediately and can only be used after passing the inspection.
10. After using the instrument, if it is found that the joint action error has increased or the contact reliability is poor, the distance between the magnetic column on the small electrical joint device and the conductive pin can be adjusted to increase the magnetic force appropriately. If it is confirmed that the magnetic force of the magnetic column has basically declined, it should be removed and replaced.
11. When using or repairing the instrument, the grounding terminal wires leading to the junction box should be reliably connected to ensure safety.
