IP68 multi-layer waterproof protection, 45-degree oblique angle with anti-impact, detachable and anti-blocking designs 4. Junction box using low copper aluminum alloy with excellent heat resistance, which can work for a long time 5. Liquid level probe and flange is made of all stainless steel, which possess strong corrosion resistance Specification: Item Type: Liquid Level Transmitter Material: Junction box-low copper aluminum alloy; liquid level probe-all stainless steel, flange-all stainless steel Model: QDW-30AMeasured Medium: Water, oil, etc. (liquid that does not corrode stainless steel) Measuring Range: (Optional) Approx. 0 ~ 1meter / 0 ~ 3.3ft Approx. 0 ~ 2meter / 0 ~ 6.6ft Approx. 0 ~ 3meter / 0 ~ 9.8ft Approx. 0 ~ 4meter / 0 ~ 13.1ft Approx. 0 ~ 5meter / 0 ~ 16.4ft Response Time: 5ms (up to 90% FS) Medium Temperature: -40~60℃, Ambient Temperature: -40~85℃ Measurement Accuracy: 0.2%FS Electrical Interface: Connection between tight-wire waterproof nut and five-core air-conducting cable Zero Temperature Drift: ±2%FS, Sensitivity Temperature Drift: ±2%FS Pressure Type: Gauge pressure, absolute pressure Insulation: 100mQ/250VDC Media Compatibility: Various media compatible with 316L stainless steel Installation Method: 1. Choose a place that is easy to operate and maintain for installation 2. Install as far away as possible from the vibration source 3. Keep away from heat sources as much as possible 4. When installing the input type liquid level transmitter, the metal probe should sink into the bottom of the container. Package List: 1 x Liquid Level Transmitter Note: 1. There is an isolation diaphragm in the pressure inlet of the transmitter, do not touch it with foreign objects;2. For electrical connection, please strictly follow the wiring method. Incorrect wiring will cause damage to the amplifier circuit;3. When installing the throw‑in type liquid level transmitter, please do not use wires to lift heavy objects other than the product;4. The probe should be cleaned regularly to avoid blockage of the pressure inlet;5. The wire is a special waterproof wire. During installation and use, the wire should be prevented from abrasion, puncture and scratches. If the above problems are exist on the site, protective measures should be taken for the wire. 6. If you encounter any problems during installation and use, please contact our company. When the product is abnormal, please do not open it for repair without authorization.
