Hopper Level Sensor 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.

Wire probe clearly structured measurement menu for volume flow and parallel determination of air velocity, volume flow and air temperature.

Wire Probe with the compatible testo multifunction measuring instrument (please order separately) to determine air velocity, volume flow and air temperature.

The probe is equipped with a telescope, which can be extended to a maximum length of 0.85 m. To ensure accurate measurement results, air density compensation is carried out via the integrated absolute pressure measurement.

The clearly structured measurement menu for volume flow makes the measuring instrument intuitive to operate. The volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed in the measuring instrument.

Integrated sensor protection: when you are not using the hot wire probe, the rotatable protective cap protects the air velocity sensor from dirt and mechanical stress.

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.

Capacitance Level Transmitter is a compact, low cost, level transmitter with 4-20 mA analogue out-put designed to measure the level of various liquids, and solid in tanks or storage vessels. Mea-suring range is 0.25 to 3 m for rod probe version. The probe forms an electrical capacitor with the surrounding metal contained wall, or with auxiliary reference probe. With the vessel empty, an initial ca-pacitances exists between the electrode And the metal well or the aux-iliary reference probe.

When the probe become covered with material to be measured the capaci-tances will increase and the change will be measured and covered into an analogue (4-20 mil) output signal proportional to the change. Rod or flexible cable can be used for various conductive or non conductive Liquids.Application : Liquids, syrups, solids, powder, cement, sugar, flour, power milk, rice, granules, chemical, etc.

Features :

  • Time delay function from 0-30 seconds.
  • IP 65 Protection.
  • Easy installation, durable, rugged
  • Suitable for sticky application, solids, powder
  • No moving parts
