2ton Capacity Load Limiter for Building Hoist/Construction Elevator with 6 Digit Display for Overload Protection
Product Introduction:
The overload limiter is a safeguarding device, which is specially designed for buidling hoist/construction elevator. The overload limiter can make alarm with sound and light, protecting the building hoist/construction elevator from being overloaded.
Technical Patrameters
| Item | Parameter | Item | Parameter |
| Display mode | 6-digit display | Rated load | 2t |
| Working temperature | -20~60℃ | Sensor working voltage | DC5-12V |
| Operating humidity | 95% | Sensitivity of the sensor | 1.0000Mv/v |
| Comprehensive error | ≤1%F.S | Installation | Slot type |
| Alarm output | AC250V/7A | Action error | ≤1%F.S |
| Buzzer | ≥90dB | | |
| Overload early warning | ≥ 95% of the rated weight(resettable); state of the relay: coil power-losing; closing of normally-closed contact; state of the buzzer: intermittent ringing (one second with two seconds interval) |
| Overload alarm | ≥ outage happens when 100% of the rated weight lasts one second(resettable); state of the relay: coil is powered, normally-closed contact is off; state of the buzzer: rapid ringing for two seconds. |
| Instant alarm | ≥ at 105% of the rated weight (immediate power off); state of the relay: coil is powered, normally-closed contact is off |
| Alarm release | Alarm relieves automatically when the load is less than rated weight. |
Sensor installation
Product Features:
1. Perfect solution for gondola/suspended platform's overload protection, with classic plastic shell, the load limiter is easy for installation;
2. High accuracy: Controller's measurement accuracy is better than 1%, which is much better than analog singal indicator;
3. Display: 6 digit display, 0000.00-9999.99, the limiter can acheive high accuracy weighing results;
4. Built-in battery: the overload limiter can work for 8 hours without power supply and will charge itself automatically once the power is resumed, making sure the building hoist/construction elevator is monitored all the time.
5. Dual way normally closed contact for power cut-off; extra buzzer and display can be connected to the overload limiter for convenience.
6. Support RS232/485 communications, can be connected with monitor screen or PC.
7. Black box function: the overload limiter can record the data up to 4,000messages of load/overload during operation
8. Easy debugging, just press one button to correct all the weighing date without actual weights;
