Cable Float Level Switch is made from resistant polypropylene. It is durable, economical, maintenance free & easy to install. And spe-cially designed for multiple point level detection in liquids. Its hermetic sealed, polypropylene body makes it suitable for sewage application. The switching ON or OFF differential is adjusted by a counterweight on the cable. The switches will transmit an ON or OFF contact signal output when the float rises and turns upwards. The switch contains a metal ball that can side as the float position changes.
Application:
- Raw Water, Sewage Open or Close Pits, ETP, STP, Waste Water, pump dry run protection

Side Mounted Level Switch are designed for use in tanks and vessels for indicating or controlling the level of a liquid. They work well as high or low level controls. Its operating princi-pal is magnetic & wetted part construction in SS. When the float magnet moves close to the switch stem, the float magnet repels the switch magnet which either opens or closes the Electrical circuit. The contact can be used to operate a pump or any device connected in series to it. These switches can either be supplied in weather proof cast aluminium switch housing.
Features:
- Rugged, Economical point level sensing
- Low, High temp
- Easy installation and Operation
- SS wetted part

Vibration Fork Level Switch is used to drive the vibration fork and feedback signal, when produces the resonation on the fork. When the fork comes into contact with material, the fork will release some frequency signal. It will be converted into the output to the signal. The vibrating frequency causes tuning forks to vibrate free inside the tank when forks are not covered with any media. Once the media covers the tuning forks, it causes damp-ing of vibrations. The damping effect of vi-brating forks is sensed by an equal circuitry which in turns gives an output electronic signal which in turn actuates a relay.
The Vibration fork level switch can be widely applied to detect the min. and max. Level in tanks, silos and hoppers filled with materials of different applications.

Displacer Type Level Switch offer the indus-trial user a wide choice of alarm and control con-figurations. Each unit utilizes a simple buoyancy principle and are well suited for simple or com-plex applications, such as foaming or surging liq-uids. Displacer type level measurement units are wide differential units calibrated to actuate as a liquid level reaches a given displacer and to de-actuate when the level reaches a second displacer. Single stage, wide differential displacer switch-es are factory calibrated yet field adjustable to operate over a wide level differential band.
Application:
- Water, Foaming or surging liquids, oils large storage tanks, juices etc

RF-Capacitance Level Switch are the Capacitance level detectors which are sometimes called as admittance level sen-sors. These sensors make use of radio frequency bal-anced impedance bridge circuit to find out whether the probe is in touch with the process material whose level is going to be detected. RF-Capacitance level switch is appropriate for appli-cation in liquid and solid mediums. Design and sensing electric unit makes it suitable for sticky media, large hoppers and storage bins. The switch is easily thread mounted an the tank and is highly reliable in operation.
RF-Capacitance level switch consists of a guard section, upper su-lation, main probe and grounding. It consists of a conductive obe which serves as one of the capacitor plate, and the vessel wall ich forms the other plate of capacitor since it is also prepared fr a conductive material. The isolation between these two plates of ca-pacitor is provided via an insulating process material having low di-electric constant. Now, for measurement purpose, an RF signal is ap-plied between the two capacitor plates which cause a little flow of current from the conductive probe to the vessel wall via process ma-terial. The probe works as an antenna to sense the frequency.
"When the level in the tank drops and the probe is ex—posed to the even less conductive vapours, the dielec—tric constant drops. This causes a drop in the capaci—tance reading and a minute drop in current flow. This change is detected by the level switch' s internal cir—cuitry and translated into a change in the relay state of the level switch".

- Liquids, Syrups, Solids, Powder, Cement, Sugar, Flour, Power milk, Rice, Granules, Chemical etc
