ZNSV6-T4-485 4CH RS485 Digital Weighing Transmitter Weighing and Force Measurement Transmitter

ZNSV6-T4-485 4CH RS485 Digital Weighing Transmitter Weighing and Force Measurement Transmitter

Description:
ZNSV6-T4-485 is a digital weighing transmitter. It can be directly connected to a Wheatstone resistive bridge-type tension/pressure sensor. Through the internal signal amplification circuit and AD acquisition circuit, the micro-voltage analog signal from the sensor is converted into a digital signal. The built-in microprocessor of the module supports calibration algorithms, allowing the real-time weight value to be directly read from the RS485 interface after calibration. The RS485 interface output by the module supports the Modbus-RTU protocol.

This product is suitable for various industrial applications such as weighing batching and force measurement. The standard Modbus-RTU communication protocol enables the module to be conveniently connected with PLCs, DCSs, microcomputers, and other devices as a front-end signal processing module for weighing.
