Level switch manufacturers, the price level switch, level switch Selection

HJ-YC tuning fork switch is a new level switch. Tuning fork crystal excited by the vibration, when the tuning fork is submerged in liquid or solid frequency changes, the frequency change is detected by the electronic circuit and the output of a switch. Tuning Fork Level Switch is also called "Electrical float", where the use of float switch and due to the structure, turbulence, agitation, bubbles, vibration and other reasons can not use the float switch can be used in case of "Electrical float." Since the level switch with no moving parts, therefore no maintenance and adjustment, float switch upgrade products. HJ-YC tuning fork switches are widely used in water, mineral water, paper pulp, glue, dyes, mud, alkali solution, acid solution, beer, beverage, petrochemical, light industry, food, water, can produce liquid gases, mobility The solid powder or granules. On the level, the lower limit alarm and control. HJ-YC tuning fork switch Features: 1, adaptability: different electrical parameters measured medium, density measurement shall not have an impact. Scaling, agitation, turbulence, bubbles, vibration, medium viscosity, high temperature, high pressure and harsh conditions have no effect on the detection; 2, without adjustment: With the fork level detection from the measured electrical parameter and medium density switching of influence, so no matter what kind of media do not require on-site measurement calibration; 3, maintenance-free: Since the detection process tuning fork level switch is completed by the electronic circuit, no moving parts, so once installed into applicable will not require maintenance. HJ-YC tuning fork switch technical parameters: 1, power supply voltage: DC 24V or AC 220V; 2, Operating temperature: fork -40 ~ 150 ℃; 3, ambient temperature: -20 ~ 70 ℃; 4, working pressure: ≤2MPa ; 5, medium density: ≥ 0.7g / cm3; 6, output: relay output (AC 220V / 5A, DC 28V / 10A); 7, output delay: 1-50 seconds adjustable; 8, power consumption: 0.5 W; 9, high and low level alarm: field can be set to HLFS (high alarm mode) or LLFS (low alarm mode); 10, electrical interface: M20 × 1.5; 11, Process connection: 1 "NPT threaded mounting (standard, optional BSPT), flange mounted (optional); 12, enclosure protection: IP65; 13, proof mark:. Ex dⅡCT4 HJ-YC tuning fork switch Use protection: (1) the feed hole is not directly aligned with fork, if you can not escape In order to prevent compaction of the bulk material falls on the tuning fork, fork above shall be set at more than 20cm fenders, or add a protective cover to avoid damage to the fork. If the material is sent when the wind deflector can be fortified. (2) Vibration a strong case can be used rope lifting prongs (must be special orders). (3) must not be the instrument provided in direct sunlight, as sunlight can set up a heat shield (4) To cable outlet case mounting hole down and add a rubber band seal to prevent infiltration of water drops crust HJ-YC tuning fork switch use: (1) Inspect the Meter before work and delay the correct time before being put into operation (2) The instrument should be regularly checked Clear Fork deposits on the body. (3) ground wire to a good contact with the container wall or earth ground resistance <2Ω. (4) tuning fork limit switch usually mounted with side-mounted bin sidewall height of the upper and lower feed position detecting when bin body openings may be inconvenient side top loading position to select the location of the material level can avoid the impact of HJ-YC tuning fork switch Ordering Information: Click the selection markers indicate the parameters; otherwise specified media name. temperature and pressure; measured material level, indicating material name, size and capacity; such as the use of other flange standards, please indicate the standard number; Please indicate whether required or protective shield flange plate HJ-YC tuning fork switch Installation instructions CAUTION: When side mounted, install the tags must be vertically upwards or downwards probe head downward about 15 ℃, when the pipeline installation must be consistent with the direction pointing mark pipeline direction
