Vibraton Switch with Local Indication Features - 3 in 1 - Vibration Transmitter - Switch - Display - Bright 3 digit LED display - Vibration range available up to 2 in/s RMS - Vibration Units: mm/s, in/s and % percentage - 2x SPDT Programmable Relay with independent time delays and 4...20mA (non isolated) analog output - Easy configuration from front keys - Set and Reset value switch with both time delay Set - Enclosure Rating for Exd Proof Overview The VDX500 Vibration Transmitter and Switch is able to monitor the amount of vibration for all types of rotating machinery such fans, pumps, motors and other industrial machines. It measures the vibration to which it is exposed and offers two independent SPDT relay outputs (each with independent time delay and on/off control) when vibration exceeds the preset values so that the equipment it is monitoring can be repaired before extensive damage and more costly repairs are required. This is referred to as Early Fault Detection. The VDX500 is well equipped for rotating machine protection applications. It has a bright 3 digit display with unit markings in mm/s, in/s, percentage %, a 4...20mA analog (non isolated) output and 2 independent SPDT relay outputs with LED status indicator per alarm. Set point and Reset point setting for both relay outputs as well as an independent time delay for each switch) is user configurable. Also, the user can configure the unit of measurement shown in the display. Vibration is monitored in r.m.s. (root mean squared), a technique considered best for general machine health. The VDX500 makes online vibration monitoring cost-effective with its optional analog output retransmission which can be connected to a PLC, DCS or other industrial control equipment.
