SMARTsaa offers entirely new range of RF admittance type Level Switches for measuring level of powder, granules and bulk solids like fly ash, coal, food grains, chemicals, slurry in hoppers and silos.APPLICATION:•Low or high level alarm•Detection of chute blockage in feeding hoppers: CHUTE BLOCK SWITCH•Detection of levels of solids, liquids granules food grains and powders, •Detection of top and bottom levels of coal bunkers•Level detection in cement silos•Level detection of Fly ash  •Level detection for Stock Pile•Level detection of pellets, granules, powders, chips and flakes•Boot level detection•Level sensing of sticky material like slurry, mud and sticky material (Consult factory)•Detection of flow or no flow •Detection of level of conducting, non conducting, organic, inorganic almost all materials •Interface detectionOPERATING PRINCIPLE:The RF Level switch operates on the basis of RF absorption. The electronic unit generates a sinusoidal wave, applied to the electrode creating a field around it. RF environment absorption changes (Electrical Loss) around the electrode are reflected on the changes of generator supply current. Such changes caused by increase in level is amplified and used to actuate the relay. Special Coat-guard amplifier is incorporated in the circuit, which will ignore the effect of deposition. The RF Admittance type, point level switch, designed with special sensing probe, using special shield coat-guard circuit and three element probe. The level switch is immune to the material built-up on the probe and material bridging between the probe and hopper wall.COAT GUARD CIRCUIT:Normal capacitance type switches may not perform if the process material builds up on the probe. The coat guard circuit is added to overcome this problem. In this circuit, additional coat guard electrode is added which is insulated from sense as well as ground electrode. The coat guard electrode is driven with the same potential and phase as sense. When there is coating on electrode, no current flows between sense and ground. When the level of the material in silo or hopper rises and covers sense electrode the switch operates.FEATURES:•Three Element coat-guards Technique: Ignores material built-up on probe.•Fast and easy installation: Simple to calibrate.•Suitable for highly dusty environment•Field selectable operation logic: Configurable high or low point switching.•Economical•Special Rod probes for slurry, mud and sticky materials•Abrasion resistant UHDMWPE insulation for disc probes•Special rod probes with ceramic coating for sensing hot material (like fly ash) up to 450 °C •Special housing with glass viewing cover ,Operation Status indication by LED•Mounting: Screwed or flanged•Heavy duty construction for use in bulk material •Cast Al enclosure for control unit, IP 66 certified•Rod probe can be mounted from any direction: Top, Bottom, Sides or Inclined •Disc probe: Side mounting on the walls of hopper, Rope Probe: Top mounting

SMARTsaa offers Electro Optic Point Level Switch series SMARtsaaEOPLS for sensing of liquid level in tanks and pipes. Finds application is beverage systems, pharmaceutical, petrochemical machines and machine tool industry and leak detection systems.The switch consists of infrared LED transmitter and receiver fitted in a transparent prism.
