The following accessories can be an optional part of the conveyors:
Type variants differ according to the used supply voltage:
Speed range: 0 - 1000 rpm. with the same accuracy
The sensor is used to measure the speed and thus to indicate a stop (cracking or other deformation of the spiral) or deceleration of the rotation of slow-running shafts, screw conveyors and spiral conveyors with a flexible shaftless spiral and end bearing. It can also be used to monitor periodic non-rotating motion. The sensor responds to changes in the distribution of ferromagnetic masses in its active zone.
The sensor consists of an evaluation unit and a sensor, which is connected to the evaluation unit with a cable with a standard length of 5 m. The cable length can be adjusted according to customer requirements, provided that the length does not exceed 10 m!
Description of the function of the evaluation unit:
The evaluation unit of the sensor (RTA-01) is a device enabling both optical control of the operation of the spiral conveyor and evaluation of the fault and subsequent shutdown of the conveyor. The unit is programmable and in cooperation with a sensor responsive to the movement of ferromagnetic material is designed for convenient operation and fully automatic mode of operation.
Basic parameters of the evaluation unit:
Description of sensor function:
The sensor is an active electromagnetic sensor, responding to the presence of metal objects in its active detection zone. The output signal of the sensor is pulsed and is fed to the evaluation unit by a cable.
Structurally, the sensor is designed to withstand mechanical and chemical influences of the environment and is resistant to interference from the 50 Hz network.
Basic sensor parameters:
!! Warning !!
Do not install on vibrating structures!
When installing the sensor on spiral conveyors type SL, SLN, SLP it is necessary to use a bearing with preparation for this type of sensor to mount the sensor.
