[Pain points in the scene]
Do traditional weighing equipment cause you three major anxieties in high-risk weighing work sites such as chemical, pharmaceutical, and energy industries?
√ Sensor angle difference leads to data drift and frequent ingredient errors
√ Stability of signal transmission in complex electromagnetic environment interference
Lack of explosion-proof certification poses safety hazards
Therefore, in hazardous environments such as chemical, pharmaceutical, and energy industries, weighing equipment must not only be accurate, but also safe and reliable. Jieman Heavy Industries launches intrinsically safe explosion-proof junction box GMA-JB4 Ex and explosion-proof weighing transmission instrument GMT-H2ex, bringing a new safe, stable, and efficient weighing solution to high-risk industrial sites!
New product one
GMA-JB4 Ex Explosion proof Weighing Junction Box - "Sensor Hub Expert"
As an intrinsically safe explosion-proof junction box, GMA-JB4 Ex is known as the "four wire sensor wiring expert" and is designed specifically for weighing applications in hazardous environments
1. Plug and play sensor integration capability
● Support fast integration of analog or digital sensors, connect up to four sensors, efficiently connect weighing instruments, and improve on-site wiring efficiency;
2. Accurately correct the four corner deviation
Built in adjustable potentiometer, easy to complete angle correction, effectively solving the problem of weighing error caused by four corner deviation, making every weighing accurate and error free;
3. Flexible sensor access switch for debugging
Each sensor interface is equipped with a reliable dip switch, which allows for flexible selection of the number of sensors to be connected. It supports independent inspection of the performance of each sensor, avoiding the hassle of repeated wire connections;
4. Intrinsic safety explosion-proof design, complete certification
Explosion proof mark of the whole machine: Ex ia II C T4 Ga, protection level: IP65, suitable for hazardous gas environment in Zone 0, ensuring the safety of personnel and equipment;
Equipped with 5 all stainless steel explosion-proof gland heads (explosion-proof mark: Ex db IIC Gb, protection level: IP66);
5. All stainless steel shell, strong anti-interference ability
The sturdy and durable 304 stainless steel body not only has good electromagnetic shielding ability, but also can resist the erosion of complex on-site environments.
