NYYCUK Tuning Fork Level Switch Level Controller

Operating Principle

Tuning fork level switch is also often called tuning fork level meter or tuning fork level controller, mainly because tuning fork level meter in different links in industrial production, the actual key role is different, people habitually called many different names. Tuning fork level switch is a kind of level switch, mainly using tuning fork resonant principle to measure the level of state, its unique fork design and inherent vibration characteristics, can ensure the automatic cleaning function of tuning fork and prevent hanging material to the maximum extent.

Tuning fork level switch is a new level control switch, it is mainly by tuning fork, through the vibration principle to measure the level of height. The working principle of tuning fork level controller is to make the tuning fork vibrate at a certain resonance frequency through a pair of piezoelectric crystals installed on the tuning fork base. When the tuning fork is in contact with the measured medium, the frequency and amplitude of the tuning fork will change. These changes will be detected by the intelligent circuit, processed and converted into a switching signal.

Technical Parameter

Design Features

◎ Suitable for measuring medium density solid powder or particles that can flow freely. Also applicable to almost all liquid media, this series of tuning fork level switches can be measured at a variety of levels, with high / low fault safety limit switches, overflow or empty operation protection, pump control, display pipes with / without flow, etc.
◎Free from the influence of foam, eddy current and gas, it is suitable for the fixed point alarm or control of all kinds of solid material level and liquid level in various containers. Multiple models can be used in different situations. Long service life, stable performance, safe and reliable
◎Strong adaptability-the measured material has different electrical parameters, and the density has no effect on the measurement. Scaling, agitation, turbulence, bubbles, vibration, medium viscosity, high temperature, high pressure and other adverse conditions do not affect the detection.
◎No adjustment is required: it is not affected by dielectric constant and density, so no field adjustment is required for any liquid measured.
◎Free from maintenance: the detection process of tuning fork switch is completed by electronic circuit, no moving parts, once installed and put into operation, no spot adjustment is required.

Application

• Pulpy, viscous, foamy or corrosive liquid.
• A solid powder or particle of medium density that can flow freely. For example, fly ash, cement, sand, stone powder, plastic particles, salt, sugar and so on.
• Liquid with explosive and non-explosive hazard, corrosive liquid (acid, alkali) high viscosity liquid. For example, water, acid, alkali, mud, pulp, dye, oil, milk, wine, beverage and so on.
• There are toxic substances.
