Rotational Speed Monitor for Conveyor Systems

ED4000 Rotational Speed Monitor for Conveyor Systems.

Overview

ED4000(SM4) Speed Monitor is a totally new rotational speed monitoring equipment; it uses the principle of photo detector and microprocessor to accurately calculate a wide range of rotational speed. It detects rang 1~999rpm and the rotational speed display on 7-seg led.

There is a contact relay that could be used either for alarm or control purposes during the monitoring process. The alarm set point could be directly set by numerical knobs which is more convenient and more accurate than conventional means. It comes equipped with analog signal output which could be utilized for various display indications and more precise control. It is ideal for applications in monitoring low speed, stop and overload situations

Applications:
- Low speed and overload protection monitoring of various conveyer systems
- Frequently used on:
- Grain and coal storage bucket elevators and belt conveyer machines

FEATURES:
- Maximum monitoring range 1~999rpm.
- 7-seg led display 0~999
- Alarm monitoring: low speed, stop, reverse, blackout and overload.
- Start up delay function allow motor to run up gradually.
- Alarm delay function can avoid fault alarm which many caused by temporary slow down or load changed.
- Selectable rotate direction for both CCW andCW makes installation more versatile.
- Light pulses are not affected by environmental conditions.
- Complementary to FineTek PB/PM series digital Panel meter to indicate speed.

Special Function (built in function)
- 4~20mA output, proportional to selectable
- speed range like 100rpm, 200rpm, 500rpm and 1,000rpm
