  • Manufacturer Part No .3090A

Product Overview

The 3090A is a hazardous location Variable Reluctance Speed Sensor designed for use in locations where explosion-proof or intrinsically safe sensors are required. Passive VRS (Variable Reluctance Speed) magnetic speed sensor is simple, rugged devices that do not require an external voltage source for operation. A permanent magnet in the sensor establishes a fixed magnetic field. The approach and passing of a ferrous metal target near the sensor pole piece (sensing area) changes the flux of the magnetic field and dynamically changing its strength. This change in magnetic field strength induces a current into a coil winding which is attached to the output terminals. The output signal of a VRS sensor is an AC voltage that varies in amplitude and wave frequency as the speed of the monitored device changes and is usually expressed in peak to peak voltage (Vp-p).

What is the difference between (part number .3090A) and (part number 3090A)

There is no difference. Honeywell used to have a dot (.) in front of some series of parts but did away with it a couple of years ago. They are the same parts
