1. 概 述
2.产品参数
| 型号 | GSD4 | 使用环境 | 温度：0℃～40℃ |
| 尺寸 | 396×129×70mm | 湿度：≤95%(25℃) | |
| 重量 | 5kg | 大气压：80kPa～106kPa | |
| 防爆形式 | 矿用本质安全型 | 基本误差 | ±0.5%FS |
| 本产品与分站距离应不超过10m，测量范围在（0.5～4）m/s，输出为（127.3～1018.6）Hz的正弦频率信号 | |||
3. 工作原理
GSD4型速度传感器滚轮、由线圈、永磁铁、左齿环和右齿环等部件组成，滚轮压在皮带上跟随皮带转动。当滚轮转动时右齿环跟随转动,左右齿环磁阻的大小随着右齿环转动而发生变化，从而导致磁通量发生变化产生感应电动势，输出与滚轮转动速度成正比的频率信号。
4.配接设备
♦ 煤矿用聚乙烯绝缘编织屏蔽聚氯乙烯护套通信软电缆
♦ ICS
♦ KDW127/5隔爆兼本安型直流稳压电源
