analog 4-20ma digital loadcell weight control transmitter
Main Features:
² Applications: Weight/Force Display, Peak Value Detection&Display Holding, Auto Weight-checking, Setpoint DO Output and AO/Digit Transmission.
² EMC design with high anti-jamming capability, suitable for industrial environment.
² 32-bit ARM CPU with 48MHz clock & high arithmetic speed.
² 6+6 Red LED digital tubes for English character and digit display.
² 4-key English keypad for Menu&Shortcut mode operation.
² 24-bit High-precision and high-speed ∑-A/D conversion module with 1/1,000,000 internal resolution and max. sampling frequency 3200Hz.
² Special anti-vibration digital filtering algorithm for ensuring the weighing stability and accuracy when there is strong vibration on the load receptor, and the rapid response capability when the weight signal changes.
² Max. Connection Quantity: 8 Loadcells (350Ω).
² Zero Upon Power Up, Zero Auto-tracking, Manual/Auto Zero and Zero Calibration available.
² Load Calibration, Data Calibration, Segmenting Span Correction and Segmenting Weight Calculation available.
² Auto-locking, Key-locking, Key-unlocking, Digital Setting&Calibration and I/O Testing functions available.
² 3 Definable normally open switch inputs [DI] and 3 definable normally open transistor switch outputs [DO].
² 1 Optional&definable current signal output [AO: 0~20mA].
² 1 Optional&definable voltage signal output [VO: 0~10V].
² RS232, optional RS485 and CANBUS communication ports for connecting Host IPC/PLC and LED Remote Display.
² With the multitasking mode, the weighing/force measuring process, alarm output and signal transmission will not be interrupted by parameter setting and the other operations.
