Overview
VBS – Vibration Switch
VBT – Vibration Transmitter
VBS - Introduction
Designed to continuously monitor changes in a machine’s vibration levelSmall, compact, and uses two easy set up dials that adjust the maximum RMS velocity set point and false trip time delayPurchase by Vrms range
VBS – Key Specifications
Housing Material: PBT, PC, FPM, and 316 SSAccuracy: < ±3%.Measuring Range: 0 to 50 mm/sEnclosure Rating: NEMA 6 (IP67)Output Signal: 4 to 20 mA.Switch Type: PNP NO (500 mA max)Agency Approval: CE
VBT - Introduction
Continuously detects the vibration in a system and monitors for unusual operating conditions and potential failureRequires no setup, and there is no software required for configuration
VBT - Key Specifications
Housing Material: 316 SSAccuracy: < ±3%Enclosure Rating: NEMA 6 (IP68)Electrical Rating: 9.6 to 32 VDCFrequency Range: 10 to 1000 HzOutput Signal: 4 to 20 mAAgency Approval: CE
Applications
Vibration switches are used to detect failures in bearing, motors, drives, or other machinery where high vibration is not normalVibration transmitters are used to monitor normal operating conditions, and give indication when machinery may be starting to wear out or fail
Applications
Vibration transmitter used to monitor vibration levels in large cooling tower fan in order to balance and align fan blades
Applications
Vibration switch used to monitor motor vibration to detect bearing failures
Applications
MountingThe placement of the vibration sensor is critical to what is being monitored, be it axial or vertical vibrations
