Liquid Level Switch Suppliers and Manufacturers

M-ELL-SA External level switch is a non-contact level switch by using the Variable frequency ultrasonic technology, it is widely applied to all kinds of liquid level detection. The measuring probe is installed on the external wall of the container. And it belongs to a completely non-contact instrument which measure the level from outside of tank. Working Principles of the External Level Switch The measuring probe of the instrument can send the ultrasonic and detect the residual vibration signal in the wall of the container. The amplitude of the residual vibration signal will becomes smaller when the liquid is over the probe. A switch signal will be outputted after such change is detected by the instrument. The Variable Frequency Ultrasonic Technology is invented by the DingHua and it is the world¡¯s leading ultrasonic signal change detection technology. The main problem for the traditional ultrasonic level switch is that the ultrasonic signal can be interfered by the attachments from the tank wall and the amplitude of residual vibration signal can be changed by the drift of the temperature and time, thus the misinformation phenomenon is easy to appear. More owned the patent of self adaptive ultrasonic technology of variable amplitude variable frequency and it can effectively eliminate the interference and drift to test the changes of the signal correctly. So that it can be applied to a variety of complex site conditions, stable and reliable long-term work. This product adopts the "micro vibration analysis" external sonar signal processing technology and leading manufacturing process, and ensure the reliability and durability of ELL-SA external variable frequency ultrasonic level switch. Application There is no need to open a hole on the tank wall to install the sensors when the ELL-SA series external level switch is installed. The instrument neither contact the liquid medium nor contact the gaseous medium in the container. Therefore, the installation is simple and quick, safe and secure. No need to clear the tank while repair and maintenance, no influence on the normal operating. ELL-SA series external level switch is applicable to fixed-point liquid level measuring and alarm of all kinds of containers and liquid. It can be widely used in petrochemical, chemical, oil depots, oil, electricity, liquid storage, pharmaceutical and other industries. And it has a significant advantage in the pressure vessel, dangerous chemical liquids, flammable and combustible liquids and fixed-point liquid level measuring and alarm fields. Product features 1¡¢Safety: the valves, communicating pipes, joints are not used in the measurement of poisonous, corrosion, pressure, easy to bums, volatile and leak liquid, and there is no leaks, no contact with the liquid and gas in the container, which is very safe. Even under the condition of instrument damage or repair, there will be no possibility for leakage, poisoning and explosion. (Measuring principle diagram) 2¡¢Easy installation and maintenance: There is no need for tank cleaning and open fire during the installation, no impact on production 3¡¢Durability and reliability: There is no mechanical moving parts in the sensor and instrument, strict sealing, isolation, will not wear or corrode. 4¡¢Widely applicable: It has nothing to do with the medium pressure, temperature, density, dielectric constant, viscosity, and presence of corrosion. carton box and gift box, according to requirement

Optomax Digital Series Liquid Level Switches General Description Optomax Digital liquid level switches are ideal for applications with restricted space that require a miniature, low power and low cost sensing solution. The microcontroller based sensor is solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid. The TTL compatible push-pull output can sink and source up to 100mA at a supply voltage range of 4.5 to 15.4Vdc and can be configured to output a high or low signal when in either a wet or dry state. A fail-safe PWM option is also available with a supply voltage range of 4.5 to 5.5Vdc. With housing options for internal or external sensor mounting and for use in two operating temperature ranges; Standard (-25 to 80'C) or Extended (-40 to 125'C). Available in two chemically resistant housing materials, Polysulfone, the standard choice for most applications or Trogamid, which is typically used in food and beverage applications.

We specialize in manufacturing a wide range of RF Type Level Switch that vary from simple, single point, low cost level to specialized & complex level. 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. Design Considerations: RF Type Level Sensors Switch have been designed taking into consideration characteristics and behavior of materials like Solids (in their granular from), Slurries and Liquids. Few important conditions are given below: Coating: Most materials have a common tendency to accumulate and coat over anything in contact like walls or any other part that protrudes inside the vessel. That happens by natural phenomena and can not be avoided completely. The Level Sensor must be unaffected by coating and accumulation of material on the sensing element or on side walls. RF Design: RF Principle based Level Sensors have been designed based on the considerations discussed and various other aspects. Flow star RF Level Sensors are highly reliable for use with materials that are conductive or non conductive, granular or slurries, fines to large particles and contaminated or pure liquids at varying temperatures and pressures. Description: Flow star RF Level Switch series FERF 200 comprises of two parts, namely a Sensing Probe and an Electronic controller. The Sensing Probe has two parts, active section and shield section insulated from each other as shown in the diagram. A dust proof Probe Head is provided to cover the terminals of the Rf signal cable. Meaning hereby, the Probe contains no electronics or any other sensitive element. The Electronic Controller separately housed in dust proof enclosure designed for outdoor duty and mounted at a convenient location. It contains the entire electronics, etc. and is connected through a coaxial cable to the Sensing Probe. Functions: Flow star RF Level Switch Series FERF200 Models work on Rf Principle. Independent but identical low power RF signals equal in frequency, phase, amplitude and wave shape generated in the Electronic Controller are provided to active and shield sections of the Sensing Probe, whereas, the reference ground of electronics is connected to the vessel shell The signal provided to the shield section is maintained constant by use of a compensating circuit in the Electronic Controller while the signal applied to the active section varies with change of media between probe and the vessel shell/wall
