Unmatched Accuracy and ReliabilityWith non-linearity and repeatability ratings of 0.02% F.S., this load cell provides exceptional measurement accuracy, ensuring consistency across repetitive industrial processes. Its robust overload protection and high insulation resistance enhance long-term reliability for consistent weight measurement in heavy-duty settings.
Superior Environmental ProtectionHermetically sealed and finished in nickel plating, the load cell achieves IP68 certification. This protects internal components from water and dust ingress, making it suitable for harsh industrial environments, including outdoor weighbridges and factory floors exposed to challenging conditions.
Versatile Connectivity and Extended Signal TransmissionThe RS485 digital interface enables secure, interference-resistant communication, allowing installation at distances of up to 1,000 meters from the monitor. This supports flexible design and easy integration in large-scale, complex weighing systems found in industrial operations across India.
FAQs of DIGITAL LOAD CELL:
Q: How does the digital load cell ensure accurate weight measurement?
A: The load cell maintains accuracy with a non-linearity and repeatability of 0.02% F.S., a zero balance of 1% F.S., and minimal creep (0.03% F.S. over 30 minutes). These features guarantee precise and stable readings in both short-term and continuous industrial weighing applications.
Q: What environmental conditions can the digital load cell withstand?
A: Designed for harsh environments, this load cell features an IP68 protection class, making it fully waterproof and dustproof. It operates reliably between -10C and +60C, ensuring consistent performance in both indoor and outdoor industrial settings.
Q: Where can this load cell be installed and used?
A: It is ideal for electronic weighbridges and various industrial weighing applications, including manufacturing plants and logistics hubs. Its bolted compression type allows stable mounting in standard installation sites commonly found in Indian industrial environments.
Q: What is the maximum distance the digital signal can be transmitted?
A: With RS485 digital connectivity, the load cell can reliably transmit signals over distances of up to 1,000 meters, enabling flexible placement away from control rooms or display units without compromising signal integrity.
Q: How is the load cell powered and what is its battery life?
A: The load cell operates on DC power between 5V and 12V and features internal electronics with a battery life of up to 36 months, providing long-term, maintenance-free operation for automated weighing systems.
Q: What benefits does the nickel-plated, hermetically sealed construction provide?
A: The nickel-plated, hermetically sealed body protects the load cell against corrosion, moisture, dust, and other contaminants, significantly extending its lifespan and maintaining performance in challenging industrial environments.
Q: How is the load cell installed and maintained?
A: Installation is straightforward with a bolted compression type mount and a standard 6-meter cable for wired connectivity. Its robust construction and overload protection require minimal maintenance, promoting longevity and reducing downtime for users.
