Name: VibeSENSE LW100 Wireless Industrial Vibration Sensor
Brand: POLWAX

Overview

The POLWAX VibeSENSE LW100 is a wireless, battery-powered industrial vibration sensor for continuous condition monitoring of rotating machines.

It measures vibration on three axes (X, Y, Z) – peak acceleration, effective (RMS) velocity and peak-to-peak displacement – together with the surface temperature of the machine, and transmits the values over LoRaWAN® to a gateway kilometres away. No signal or power cables are needed: the replaceable 8,500 mAh battery powers the sensor for years, and the IP67 housing with stud or magnetic mounting installs in minutes. Bearing wear, unbalance, misalignment, looseness and overheating become visible long before a breakdown.

Installation & environment

Stud mounting (S) for permanent monitoring and best signal transmission; magnetic mounting (M) for fast installation without drilling on a ferromagnetic surface.
Mount on the bearing housing, as close as possible to the load zone; avoid thin covers, fan hoods and sheet metal.
Keep the cap free – do not mount inside closed metal enclosures, cover the cap with metal guards or paint it with metallic paint.
