Tuning fork level sensor free#

Status indication: Green light: indicate power supply. The first piezoelectric element triggered by a pulse signal. Magnetic testing: Output function test performed by putting magnets near the indicated spot Tuning fork level switch operated by using two piezoelectric elements built in on vibration tube. The Tuning Fork Sensors are based on the principle of dual tuning forks, which vibrate at low frequencies. Supply voltage & output: 12~55 Vdc 3 wire PNP/ NPN Output.ĭensity: >/= 0.7g/cm ³ Viscosity:1~10000 cSt Therefore, there is no signal amplification circuit inside, which can eliminate the trouble of frequent sensitivity adjustment due to the material change. The product relies on the damping effect by covering the testing material on the tuning fork which reduces the vibration frequency of the tuning fork and outputs a switch signal. It will be converted into the output of the contact signal when the circuit detects the frequency decrease of the signal. List of famous places of Delhi: Lotus Temple. Delhis warm hospitality and an openess to multi-cultural practices is a shared value with Sapcon Instruments. When the fork comes into contact with a material, the fork will release some frequency signal as feedback. Sapcon Instruments has had presence in the Delhi via its sales parter in the region since the year 1985. No need for adjustment - since the detection of tuning fork limit switch is not affected by the electrical parameters and density of the measured medium, no matter what liquid is measured, it does not need to be adjusted on site.The piezoelectric component is used to drive the tuning fork and feedback signal, which produces the resonation on the fork.

Maintenance free - since the detection process of tuning fork limit switch is completed by electronic circuit and there are no moving parts, maintenance is not required once it is installed and put into operation.ģ. Harsh conditions such as scaling, agitation, turbulence, bubbles, vibration, medium viscosity, high temperature and high pressure also have no impact on the detection.Ģ. Strong adaptability - different electrical parameters and densities of the tested materials have no impact on the measurement. For all kinds of liquids, such as slurry, sticky, easy to foam, corrosive and other media limit detection.ġ.

It is mainly aimed at the powder and small particle materials with a wide range of density, such as the detection of inlet and outlet pipe blockage of the dust collector, the material level measurement of the ash hopper of the dust collector, and the limit measurement of plastics, rubber powder, flour, various grain crops, food, chemical products and so on. Tuning fork switches are usually used with level meters to control and measure materials. Figure 1: Vital Product Image 2 Operating Principle A specially shaped tuning fork is kept vibrating using piezo-electric elements.

It has no moving parts and can replace rotating paddle level switch in most applications. where the process temperature ranges between 0 C to +150 C. G1 ', G3/4' thread or Flange (Customize) able for level detection in silos, bins, hoppers, etc. It may indicate that under customary adjustment Designed around the tuning fork principle, it consists of a two-pronged fork which vibrates at its natural frequency. Tuning fork and output were working condition, all with LED indication Models are easy to use and applications include mining, chemical processing, and food & beverage. Cost effective models are an ideal choice for level control of powders and fine grained solids. It is practical and simple, reliable, and applicability Product catalog Switching Vibration VEGAWAVE 61 VEGAWAVE 61 Vibrating level switch for powders For powdery and fine-grained bulk solids from density 8 g/l compact version Application area It detects the limit level reliably and with millimetre accuracy directly at the mounting position. Tuning Fork level switches are sensors with an electrical contact output at a specific level. The tuning fork level switch can be widely applied. Tuning fork switches by Brkert Limit level detection & dry run protection in vessels and pipes Order vibration limit & fill level switches now. These changes will be detected by the internal electronic circuits, and then after treatment, converted into a switching signal. vibration frequency of the tuning fork and outputs a switch signal. Drastically reduced the amplitude and the frequency and phase of significant change. The vibrating fork type level switch working principle is based upon detecting the change in harmonic vibration frequency of the sensing element as a result of.

Tuning fork vibrating level switches, by resonant piezoelectric crystal to cause their vibration,When subjected to material damping.
