The oil spill electrostatic protection device is designed for petrochemical products ensure electrostatic circuit grounded and prevent spillage during loading and unloading and design. Mainly applicable to flammable and explosive depots and gas stations, but also for liquid benzene, hydrocarbons and other chemical products loading seal canned system. Static grounding, liquid overflow of the object is a liquid filling process depots and chemical production units. Faced with dangerous places and dangerous liquids, the device uses flameproof and intrinsically safe manner designed: chassis Explosion-proof control box, mark ExdiaIIBT6; probe and ground clip using intrinsically safe barrier sign iaIIBT6 liquid filling process. The static grounding and liquid overflow monitoring and output control, in order to prevent accidents, ensure the safety of the production process. Electrostatic liquid filling process, the use of safety grounding clamp grounding resistance testing <62Ω is effectively grounded; otherwise ineffective grounding, the output control signal interruption liquid filling process. In the canning liquid overflow, using probes to detect overflow when the liquid touches the probe, the detected waveform changes, the output control signal interruption liquid filling process. The product is due to the production process for safety, security and reliability of the device itself is more important. Static grounding overflow monitoring unit currently used for similar products in advanced technology, the use of monitoring and control integrated design scheme, the machine uses a high-powered microcontroller core, effectively improve the product's hardware performance and reliability, SCM's own watchdog (WDT) process technology to prevent machine crashes, the program deviation or environmental interference is not working. Software designed to strengthen the self-checking features of the product, and the electrostatic chuck touchdown jitter probe momentary overflow liquid intrusion fluctuations, with anti-shake function, interference and delay treatment. Function: Detection of static during the loading and level alarm status Model: AW-JY-01 proof grade: Exd (ia) IIBT4, can be used in Zone 0; signal output: the amount or level switch; Operating voltage: 24VAC ± 10%; Operating Current: 15mA; ambient temperature: -40 ~ 60 ° C; Humidity: <85%.
