FineTek EDX Speed Monitor for Belt Conveyors
Belt slip, an overload or a stalled pulley all show up first as a change in shaft speed. The FineTek EDX speed monitor watches that speed and raises an alarm or trips the conveyor before the problem gets worse.
How It Works
The EDX senses the rotation of a pulley or shaft with an optoelectronic or magnetic-induction pickup, in contact or non-contact form. It shows speed from 1 to 999 rpm, sends a 4–20 mA speed signal to the PLC or DCS, and switches an alarm relay when the speed drops below the set point set on the adjustment knob. A start-up delay stops false alarms while the conveyor accelerates, and an output delay rides through brief speed dips when material drops onto the belt.
Key Features
- Speed range 1–999 rpm with built-in display
- 4–20 mA analog output proportional to speed
- Alarm relay for underspeed, stop, reverse, blackout and overload, rated 5 A at 250 VAC
- Knob-type alarm set point for quick setting
- Selectable start-up delay and output delay to avoid false alarms
- Contact and non-contact sensing options
- Clear status indication
Applications
- Belt slip and underspeed protection on conveyors
- Bucket elevator speed monitoring
- Stacker/reclaimer, tripper, shuttle and ship-loading conveyors
- Sequential start and stop of conveyor chains
Frequently Asked Questions
What does a conveyor speed monitor detect?
Slip, underspeed, stoppage and overload, by watching the rotation speed of a pulley or shaft.
Will it false-trip when the conveyor starts?
No. A selectable start-up delay holds off the alarm while the conveyor reaches speed.
What outputs does the EDX provide?
A 4–20 mA speed signal and an alarm relay rated 5 A at 250 VAC.
