SHINKAWA VM-701B/NB1/TRP/TB1 – 4‑Channel Vibration & Displacement Monitor Module
Product Overview
The VM-701B/NB1/TRP/TB1 is a high‑performance monitor module from the SHINKAWA VM‑7 series, designed for condition monitoring of rotating machinery such as turbines, compressors, and generators. It supports up to four input channels, handling 11 types of vibration and displacement measurements, including shaft vibration, thrust position, and differential expansion. The /NB1, /TRP, and /TB1 suffixes denote non‑incendive certification, tropicalized coating, and enhanced terminal block options for harsh industrial environments新川電機株式会社. This module delivers accurate, real‑time data to prevent unexpected downtime and ensure operational safety in oil, gas, and power plants.
