Operation
Combining vibration sensor and signal transmitter in a single package, these devices provide the ideal solution for sensing vibration and transmitting an industry standard 4- 20 mA signal directly to process monitors, controllers, or control systems.
Employing no moving parts, the basic transmitter consists of a precision accelerometer, signal conditioner, and cur-rent drive circuit, using all solid state components.
The transmitter is epoxy encapsulated in a zinc planted steel housing. The transmitters are installed by screwing the integral NPT mounting stud into a tapped hole in the machine casing.
Each transmitter is factory calibrated to the nameplate sensitivity. If desired, the zero and span controls can be adjusted in the field. 8590, 8591, 8592
Model 8590 is a non-indicating version which senses peak vibration velocity in the range 0 to 1.0 in/sec or 0 to 2.0 in/sec. It can be supplied with a screw cover elbow fitting for field wiring connec-tions.
Model 8591 is an indicating version of Model 8590. It comes with an integral 2-1/2 digit LCD display for local vibration indication. The LCD indicator is packaged in a sealed module that can be posi-tioned in 90° increments within the elbow fitting to allow proper viewing when the transmitter is in-stalled.
Model 8592 is a non-indicating version for low frequency applications. It senses peak-to-peak vibration displacement in the range 0 to 20 mils, 0 to 50 mils, or 0 to 100 mils. |
