1、General De scription MSFP-5 intelligent protector for travelling blocks, which is newly developed by mind science and technology Co., is an intelligent electronic control instrument. It is used for controlling the travelling of the travelling block in preset upper and lower limits. It is equipped dual screen for digital and diagram display to provide a real-time position of the travelling block to the operators2、The Major Technical Parameters and PrecisionDraw Works Speed : MAX 3000r/minOperation Temperature : -40~65℃Time of Battery Charging : 8hSize of Encoder: 180*60*60mmLoss of Pneumatic Pressure: Max 2%Power of Solenoid Value : DC24, 2.0ADigital Display of Travelling Block : 3digits, red LEDDisplay Precision: ±0.1% MSFP-F Hook Load Protector1、General De scription The type of hook load protector is an electronic indication apparatus with stable structure, it is used for monitoring the pressure changes of the hydraulic pressure system of weight indicator2、Brief Operation PrincipleA micro-processor is placed in the master computer (machine),the hook load sensor is placed on the hydraulic pressure pipeline, the current signal that is in proportion with the hydraulic pressure in the cylinder is transferred to the master computer, a simulating-digital converting circuit in the master computer (machine) is used to transmit the signal to the processor, where the hook load is computed with digital processing technique. The limit value of warning of the actual load is contrasted with that of presetting one for the purpose of hook over load protection.3、Technical ParametersOperation Temperature: -20~55℃Power Supply: DC24V, 2AMaster Computer: 251*192*85mmDisplay Precision: ±0.2%Setting of On/off Switch: rotary switchPushbutton: instantaneous correctionWeight of Loading: about 6kgLoad Display: 0~2000KNRelative Moisture: 35~85%RHGrade of Anti-explosion: EXD Ⅱ BT4Grade of Protection: IP65Ability of Anti-noise: 1000Vp-p, pulse width/micro, frequency 30~100HZ
