F500 ultrasonic distance transducer,ultrasonic level transducer,ultrasonic level sensor for long range. Product Overviews 1 Overview The DF500 is one type of ultrasonic level sensor which measure the liquid level without drilling hole on container. The resolution is 1mm or 0.1%FS (the bigger value). It is applicable for the close container or open container which thickness is less than 5mm. Steel tank or plastic are applicable. Output is optional for 0-5V, RS232 and RS485, it is easy to integrate into the embedded system or SCADA. In order to realize remote monitoring, there are wireless version for DF500, including zigbee, Wifi, GPRS, 3G by working with our wireless module. Furthermore, GPS module is one optional for the DF500. 2 Specification

NO. | Item | Quantity | Remark |
1 | Controller Box | 1 | Drive ultrasonic transducer and output signal |
2 | Ultrasonic Transducer | 1 | Transducer attached to bottom of container |
3 | Transducer Extended Wire | 1 | 7 meters |
4 | Power and Signal Cable | 1 | Power supply and signal output |
5 | Transducer Protection | 1 | Protect transducer, not necessary |
6 | Double Faced Tape | 1 | For aluminium alloy , plastic container |
7 | Tie | 1 | Fasten transducer and cable |
8 | Abrasive Paper | 1 | Clean the coating of installation point |
9 * | Couplant (vaseline) | 1 | Put between the transducer and container While finding the installation point |
10 * | Glue | 1 | Put between transducer and container for real installation after installation point found. Applicable for aluminium alloy, steel, plastic tank. Recommend loctite 380 glue. |
*: The couplant and glue is forbidden to delivery for airplane shipping or express shipping. So we do not offer them in the standard package. Please purchase at local market. The couplant (vaseline) is easy to find at medical store. It is applicable only if the glue can work for your container and the transducer.
The LED Display tool is helpful to find the good installation point during installation. It is not included in standard package. One led tool is enough for multiple DF550 installation. 7 Analog Value Interpretation For the analog output, it is 0-5V map to 0-100cm linearly. For example, if the output is 2.5V, then the level is 50cm. Please notified that, there is voltage lost on the cables. So if the controller box output 2.5V, maybe your device can only get 2.4V after the signal cable transmission. Our Services Deliver by DHL/UPS/FedEx/EMS optional
