Overview
Aeco Rotation Control Sensors monitor the interval between two pulses detected in rotary or linear motion mechanisms. Three versions are supplied: two with the M30 sensor version using inductive detection for deceleration control (CRT30) and acceleration control (CRT30A) and one consisting of an electronic unit (CRTP) capable of receiving signals from inductive, capacitive, or photoelectric sensors of various sizes and types.
The latter is used to monitor the deceleration or standstill of the rotating part, and its programmable functions include the option to observe the standstill condition of the shaft and issue an alarm if movement is detected.
Aeco Rotation Control Sensors
Rotation Control-Shaft StandStill
The CRTP rotation control or speed control is used to control the speed of a rotating shaft or its stopping. The device controls the time interval between two pulses detected by a sensor in mechanisms with rotating or rectilinear movement. If this time becomes more significant than the one set on the device, an alarm sounds which signals the decrease in speed or stop of the mechanical unit.
This device represents an excellent solution for verifying sliding, conveyor breakage, overload, etc. in equipment such as conveyor belts, bucket elevators, crushers, grinders, pumps, mixers, and other equipment where slowing down or stopping due to mechanical breakage or abnormal functioning needs to be controlled. The same device, properly programmed, can check the condition of the shaft stop, signaling an alarm in case of movement.
The rotation control consists of an electronic CRTP unit with various programming possibilities and a detection sensor with an inductive, capacitive or photoelectric principle in the NAMUR-NPN-PNP versions. The device is powered in alternating current with relay output with a changeover contact. The combination of sensors with different detection systems and various shapes and sizes allows the use of the CRTP rotation or stop control to be used in a wide range of applications.
SPEED CONTROL (special version)
This rotation control version, in addition to the features described for the CRTP model, can be programmed for two operational modes referring to a rotary or linear unit: one for control of reduced speed (under speed) and the other for control of increased speed (Overspeed). In both the versions mentioned above, the device includes the standstill safety control. The technical and operational characteristics can be found by clicking on “Technical Features” below.
Slowdown Control Sensors
The slowdown control sensors CRT30 series are presented as an M30 threaded metal sensor with inductive detection with intervention distances between 4 and 6 mm on metallic material. They are used to control the speed slowdown of a rotary or linear movement, verifying that the time detected by the sensor between two pulses does not become higher than the one set due to a slowdown or stop because of a mechanical malfunction in conveyor belts, bucket elevators, mixers, etc.
The device contains both the metal-sensitive inductive detection system and the deceleration control system. Furthermore, the power supply voltage of 18÷50Vdc and 18÷240Vac, the various programming possibilities, and the exchange relay output make it a compact and practical device for the fitter to use. This device represents an excellent solution for verifying sliding, conveyor breakage, overload, etc. in equipment such as conveyor belts, bucket elevators, crushers, grinders, pumps, mixers, and other equipment where slowing down or stopping due to mechanical breakage or abnormal functioning needs to be controlled.
Overspeed Control Sensor
The Overspeed control sensor CRT30A type is presented as an M30 threaded metal sensor with inductive detection with intervention distances between 4 and 6 mm on metallic material.
It is used to control the speed acceleration (Overspeed) of a rotary or linear movement, verifying that the time detected by the sensor between two pulses does not become less than the one set due to an acceleration caused by a mechanical malfunction in equipment where it is necessary to check that the permissible speed is exceeded. The device contains both the metal-sensitive inductive detection system and the acceleration control system. Furthermore, the power supply voltage of 18÷50Vdc and 18÷240Vac and the exchange relay output make it a compact and practical device for the fitter to use.
