Overview
The Bi-Directional Shaft Speed Tachometer System consists of two proximity sensors, a Signal Conditioner (STC-207C) and a Digital Display (STC-DMT). The sensors detect the metallic target (mounted on the propeller shaft or other machinery shaft) and produce a frequency signal which is read by the Signal Conditioner. The Signal Conditioner will send data via a RS-485 data link to the digital display which shows the RPM readings.
Features
- Highly accurate (accurate within 1 rpm)
- Reliable operation
- Speed range from 0 rpm up to 1500 rpm
- Bi-directional operation (using a single target)
- Wide air gap between pickup and target (<= 5mm)
- Independent zero and span adjustments
- High quality, illuminated digital meter (with RPM scale and digital RPM readout)
- Panel Mountable Digital Meter (DIN Box)
- Auto dimming LED display
- Able to interface to more than 10 digital meters!
- Able to work across long cabling distances (up to 300 meters)
Application
- Best suited for monitoring speed and direction of rotation of marine propeller shafts and other low to moderate speed machineries
