Technical Specifications Strain‑gauge sensor input port, analog output channel and digital communication interface. Auxiliary working power supply. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Integrated sensor excitation source and multi‑stage signal filtering circuit.
Functional Features Provides stable excitation voltage for strain‑gauge tension sensor. Captures tiny differential tension signal from load cell. Executes signal amplification, noise filtering and tension value computation. Transmits tension measurement result to upper‑level controller through analog output or digital bus. Front‑panel LED indicators show power‑on status, measurement running state and fault alarm. Built‑in hardware self‑diagnosis detects sensor wire breakage, short‑circuit and internal circuit failure.
Application Scenarios Spare tension measuring module for papermaking, film production, textile and metal foil rolling production lines. Used for cabinet maintenance and spare‑part replacement of web processing equipment.
Performance Parameters High‑gain low‑drift signal amplification. Accurate real‑time tension value output. Reliable sensor loop fault identification capability.
Material Composition Metal protective housing. Multilayer glass‑fiber epoxy printed circuit board. Sensor excitation unit, signal amplification and digital processing assemblies. Screw terminals for sensor input, analog output and communication wiring.
Structural Characteristics Compact rack‑mount unit. Front panel fitted with status indicator lamps. Signal terminals located on lower part of housing. Standard mounting holes for DIN‑rack installation.
Working PrincipleAfter amplification and filtering processing, microprocessor computes tension value, and sends measurement data to host controller via analog channel or digital communication. Diagnosis circuit continuously monitors sensor connection and hardware operating condition.
Installation Requirements Connect shielded sensor cable and host control wiring strictly follow terminal definition, implement correct shield grounding. Restore power supply, complete zero‑point and span calibration, verify measured tension value matches actual mechanical load.
Usage Notes Keep sensor signal cable away from high‑voltage power cables to avoid electromagnetic interference. Zero‑span calibration must be performed after hardware replacement.
