Product Introduction

Functional Features
Dual channel design: It has two independent measurement channels, which can simultaneously measure two signal sources. Each channel can work independently and can also perform addition, subtraction, and other operations on the measurement results of the two channels.
Multiple signal measurement: It can measure static and dynamic signals of physical quantities such as displacement, angle, force, torsional vibration, etc., and is often used to measure shaft displacement.
Wide frequency range: The signal frequency range can reach 0-100Hz.
Flexible zero adjustment: Zero adjustment and zero offset are independent of the selected measurement range, facilitating calibration and compensation.
Strong anti-interference ability: The sensor power supply has balanced grounding, which can effectively suppress interference in industrial environments.
Rich communication interfaces: Equipped with RS232 interface for configuring and reading measurement results, RS485 interface can be connected to EPRO's MMS6800 analysis and diagnosis system or upper computer.
Improve self checking function: It has extended self checking function, built-in sensor self checking function, and password protection operation level to ensure the reliability and safety of measurement.
