Introduction
This document contains information on the installation, operation, and
maintenance of the Intrinsically Safe Vibration Sensor.
Intrinsic Safety (IS) is based on the principle that the electrical energy in
hazardous-area circuits is deliberately restricted such that any electrical sparks or
hot spots that may occur are too weak to cause ignition. This is achieved by
inserting an energy limiting interface in the wiring between safe and hazardous
areas. The interface passes signals in either direction as required but limits the
voltage and current that can reach the hazardous area under fault conditions. It
may be integral with the safe-area equipment or separate for greater flexibility.
Description
Accelerometers will produce a voltage output that is proportional to the vibration
output (in g’s) the sensor is experiencing. 4-20mA Vibration Sensors will create
a 4-20mA output proportional to the specified full scale range of sensor (for 4-
20mA acceleration model), or integrates accelerometer (g’s) to velocity and then
creates a 4-20 mA output proportional to the full scale range specified by the part
ordered.
