AND Micro balance AD-4212B-301
Description – Precision Weighing Sensor
-
The AD‑4212B‑301 from A&D combines powerful precision with industrial resilience, delivering accurate results even in challenging environments.
-
Features C‑SHS (Compact Super Hybrid Sensor) technology and a responsive EM‑DLC analog‑to‑digital converter.
-
Built for in‑line production, checkweighing, automated dosing, and sensitive laboratory tasks.
-
Offers 0.1 mg readability across a generous 310 g capacity – ideal for applications that demand both extended range and precise output.
-
High capacity with fine resolution – measures up to 310 g with 0.1 mg readability.
-
Fast and reliable:
-
Repeatability: 0.2 mg
-
Linearity: ±0.3 mg
-
Stabilisation time: approximately 2.5 seconds
-
-
Ensures consistent, quick readings for time‑sensitive or automated processes.
-
Industrial‑grade durability – compact housing resists vertical and transverse overloads, making it suitable for integration into enclosed machinery or space‑constrained setups.
-
Application versatility:
-
Animal weighing mode – stabilises fluctuating weights for live samples
-
Comparator mode – enables pass/fail decisions for sorting or process control (HI/OK/LO)
-
Counting mode – offers accurate part counting, even for very small items
-
-
Seamless integration with automation:
-
Ethernet / LAN – enables remote data management and system control
-
RS‑232C – supports standard serial communication with external devices (PCs, printers, PLCs)
-
-
Breeze break – not included (sensor is designed for enclosed or shielded environments)
-
Ideal for precision production, pharmaceutical/chemical/electronics manufacturing, OEM automation systems, and advanced laboratories.
