1. The weighing sensor can work normally under the following conditions: 

 Ambient temperature：0℃~+40℃ 

 Relative humidity：≤95±3%（+25℃）

 Atmospheric pressure：80kPa~106kPa 

Working in underground coal mine with explosive gas. 

2. Design feature

The weighing sensor consists of cylinder, piston, hydraulic oil and transmitter components, compact structure, firm and durable, convenient installation, flexible use,stable performance. Device protection grade: IP65

3.Operational principle

Weighing sensor using pressure transducer as an element of the pressure (called the object's gravity) into a weak signal, signal after amplification processed into standard 4~20mA signals, the current dependence of transmission to the analog signal equipment associated with the PLC end, as the measurement control signal.
