DH-S series of belt speed detector 
 Speed detector detector detector belt speed 
 DH-S series of belt speed detector can be used for monitoring the speed conveyor belt, when the monitoring of the transport belt speed is lower (higher) than the preset value, an alarm or stop signal it can effectively avoid accidents. Can be used in metallurgy, coal, mining, cement, electricity, food and other industries in the belt conveyor, is the material handling system and automatic control monitoring device indispensable. ? Belt speed detector has one (or two) 1 999 r / min can be arbitrarily set alarm point. 
 ? 0 ~ 30 seconds to set the alarm delay function action. 
 ? Speed detector direction of rotation without limitation, forward and reverse rotation are available. 
 ? Speed detection device using two-wire transmission, the transmission distance up to 2 km, and no separate power supply. 
 ? A delay of 10 seconds after power output, to avoid low speed when the machine starts. 
 ? Speed detector has DC110V, DC24V, AC220V, and other power options. 
 ? Speed detector with power supply, alarm movements, and other LED displays.
