Langke XK3150-EX Explosion proof Platform Scale Performance Features:

Explosion proof electronic weighing apparatus is based on commonly used electronic weighing apparatus, and adopts various technical measures such as voltage reduction, current limiting, isolation, sealing, and optical cable communication to eliminate or block the possible ignition sources (electrical sparks, electrostatic sparks, high temperature...) in the electrical circuits inside the weighing apparatus, so that the electronic weighing apparatus can work safely and reliably in the corresponding hazardous areas.

Langke XK3150-EX Explosion proof Platform Scale Purpose:

EXIB intrinsically safe explosion-proof electronic scales are widely used for weighing in chemical, pharmaceutical, flammable and explosive places, as well as other explosion-proof industrial applications, such as gas companies, gas stations, chemical plants, etc. Various capacities and sizes can meet different application requirements. Multiple explosion-proof instruments can be configured to form a complete scale. The explosion-proof level of the weighing system is determined by the lower explosion-proof level in the system.

[Langke XK3150-EX Explosion proof Platform Scale] Functional Features:

Electronic scale instruments with analog signal output must have weighing function. After setting the weighing value, the working state of the weight control solenoid valve can be controlled. Large weighing/division values: 30kg/2g, 60kg/5g, 100kg/100g, 150kg/100g, 300kg/20g, 500kg/50g, etc. The weighing table size and scale body material can be customized according to customer requirements. The optional function is generally an RS-232 communication interface, which can connect computers and printers, switch signals, and 4-20mA current control signals. Electronic scales with analog signal output and electronic scales with alarm RS-232 communication interface mainly use weighing display instruments to output switch signals, which are amplified by transistors to drive relays and control the on/off status of solenoid valves
