Adding a vibration sensor/transmitter to the machine provides a critical measure of the machine's health . It can be used to identify changes in balance, alignment, gears, bearings, and many other potential faults . The purpose of the 4-20 mA analog current loop is to transmit the signal from an analog vibration sensor over a distance in the form of a 4-20 mA current signal . The current signal generated is proportional to the overall vibration of the equipment or machinery that is being monitored . This output current has a range of 4-20 mA, with 4 representing the minimum and 20 representing maximum amplitudes (within the range of 4-20 mA) . The 4-20 mA signal output is proportional to the overall amplitude generated within a defined frequency band . Therefore, the signal does not include data from frequencies outside the frequency band but includes all vibration (critical and non-critical faults) within that band . LP802 Series Overview Each LP802 sensor that is approved for Intrinsic Safety must meet or exceed the requirements for standards recognized by the countries that would use the sensors .

As shown, properly installed barriers are required to limit the energy the sensor can receive . Cabling brings the signal from the sensor to the Zener diode barrier or galvanic isolator, which is the energy-limiting interface . The signal is transferred through the barrier (which can be located in a Class I Div 2 or non-hazardous area) to measurement equipment, such as a data collector or junction box, for further processing .

Permanent/Stud Mounting Surface Preparation 1 . Prepare flat surface using a spot face tool and pilot drill hole using a CTC spot face installation tool . 2 . The mounting surface should be clean and free from any residue or paint . 3 . Tap for required thread ( �-28 or M6x1) . 4 .
