#Fork type level switch series

Figure 5 shows the timing chart of this mechanism. This enables control of relay X to be switched ON and OFF between E 1 and E 2.

When the liquid level falls below E 2, the circuit made through the electrode circuit opens, which de-energizes relay X, thus closing the NC contact of X. The vibronic sensor detects the level of solids, granules and. This kind of circuit made from electrode E 2 and a contact is called a self-holding circuit. Vibrating fork type level switch based on tuning forks amplitude measurement principle. Even if the liquid level falls below E 1, the electrical circuit made through the liquid and the electrodes is retained by E 2 and E 3, as long as contact a2 is closed. Maximum and minimum level detection in tanks containing different types. When electrode E 1 is in contact with the conductive liquid (as in point 2 of previous section), relay X operates and switches to the a side. The Rosemount 2120 Vibrating Fork Liquid Level Switch is designed for use in.

It is suit-able for level detection in silos, bins, hoppers, etc. Nagpur, Nashik, Thane, Washim, Pune, Ahmednagar, Solapur, Amravathi, Mumbai, Aurangabad, Kolhapur,Navi Mumbai, Dhule, Chandrapur,etc. LVSW-701-Switch 316 SS Single Point Ultrasonic Liquid Level Switch The LVSW-701 Series liquid level switch is a direct replacement for mechanical float-type devices. Vital is a vibrating fork level limit switch for free-owing solids having a maximum granule size 12 mm. We are Exporters & Suppliers in Following States Maharashtra: We at Process Control Devices manufacturer tuning fork level switches in Mumbai India. 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. This device can withstand static electricity. Tuning fork of the level switch provides reliable & maintenance-free for bulk solids. When the probe comes into contact with the fluid, it will cause the frequency change of output signal and the vibration will hold and send out the relay on at the same time. The first piezoelectric element triggered by a pulse signal that created from circuit to transport vibration energy out and the other piezoelectric element receives the vibration and transmits it to output electric signal. Tuning fork level switch operated by using two piezoelectric elements built in on vibration tube. By selecting the option of direct load switching electronics. If the vibrating probe comes into contact with the.

The tuning fork type level switches working principle based upon detecting the change in harmonic vibration frequency of the sensing element as a result of the presence of the target media. (50 mm) (dependant on connection type), the 2120 can be installed in even small diameter pipes. The basis of point level detection with vibrating level switches is a tuning fork, i.e. Process Control Devices offers a series of level switches designed to detect & control the level of liquid within a tank.
