Product Overview: ULYC tuning fork level switch is a new level control instrumentation. Electronic circuit excited by the vibration fork when the fork is immersed in liquid or solid, the vibration frequency changes, the frequency change is detected by the electronic circuit, and it outputs a switching signal. The instrument has driven low-power, simple mechanical structure, maintenance-free, no wear, long operating life, sensitive and reliable. Tuning fork level switch, also known as "Electrical float", all due to the structure, turbulence, agitation, bubbles, vibration and other reasons not to use the occasion float level switch, can be used tuning fork level switch instead. As the tuning fork level switch with no moving parts, so maintenance and adjustments can be called a float level switch upgrade products. Tuning Fork Level Switch is widely used in chemical industry, light industry, food, water treatment and other industries, on the level, the lower limit level alarm and control. Features: 1, adaptable: the object of different electrical parameters, density measuring small impact. Agitation, turbulence, bubbles, general vibration, medium viscosity, high temperature, high pressure and harsh conditions on the detection of less impact. 2, no adjustment: Since tuning fork level switch detects little affected by the measured electrical parameters and density of the medium, so no matter what kind of objects are not required to measure site adjustment. 3, maintenance-free: Since the detection process is completed by the tuning fork limit switch electronic circuit, no moving parts, so once installed and put into operation will not require maintenance. Typical applications: 1, water, mineral water, paper pulp, glue, dye. 2, mud, alkali solution, an acid solution. 3, beer, beverage, can produce liquid gases. 4, good mobility solid powder. Technical parameters: 1, supply voltage: DC24V, AC220V; 2, Output: relay output (AC220V/5A, DC28V/10A); 3, Working temperature: -40 ~ 150 ℃; 4, Ambient temperature: -20 ~ 70 ℃ ; 5, working pressure: ≤ 2MPa; 6, medium density: ≥ 0.6g/cm3; 7, output delay: 0.3,1,3,10,30 seconds, default 1 second, user-adjustable; 8, power consumption : 1.5W; 9, high and low level alarm: the scene can be set to HLFS (high alarm mode) or LLFS (low alarm mode); 10 Electrical Interface: G1 / 2 "(female); 11 Process connection: 1" NPT threaded mounting (standard, optional BSPT); flange mounting (optional); 12, enclosure protection: IP65; 13, Ex-mark: Ex d Ⅱ CT4;
