Top Loading Oil Controller

Top Loading Oil Controller, Overfill Detection Controller Vavle, Overfill Detection System 1   System introduction  ET - SLC-T overfill detection-top  loading and grounding controller is designed for  top loading oil system , can effectively prevent liquid overflow and ensure the  grounding resistance conforms to the safety standards of instrumentation, system for oil storage and transportation of chemical products. Ex-mark is Exd[ia]IIBT4. 2  The system working principle and composition 2.1 working principle  ET - SLC-T overfill detection-top  loading and grounding controller is designed for the top loading oil  system .  when the liquid level exceeds alarm position or ground loop in excess of the prescribed value, the system output sound and light alarm signal for field personnel understand the system working status in time, at the same time the output relay switch control signal. 2.2 The system composition and function ET - SLC -T overfill detection-top  loading and grounding controller is mainly composed of the main controller, ET- AL sound and light alarm,  ET - OP - T overfill sensor, ET - SC - T clamp, ET - RP  return plate, ground wire . 3    the product characteristics 1. The system uses digital circuit design, stable performance, strong anti-interference ability; 2. The overfill sensor using optical principle, the overall epoxy resin casting, anti-corrosion, waterproof; 3. The overfill sensor has fault alarm function; 4.Provide sound and light alarm signal, in a timely manner to understand system working state; 5.Switch signal output interface capacity 10A, 30 VDC or 10 A, 250 VAC. 4   System parameters 1. Working voltage: 220 VAC ± 10% 2. The working current: < 20 mA 3. The working temperature: - 40 ℃ ~ 60 ℃ 4. Response time: < 0.5 s 5. Grounding resistance: < 55 Ω 6. Protection grade: Ip65 7. Ex-mark : Exd[ia] IIBT4 8. Warning: sound and light ....
