Sensor
position of the wedge of the rotary table of the DKR
.
Sensor DKR is designed to determine the position of the wedge rotor table. It is installed in the rupture of the pneumatic system of the drive of the rotor wedges with the help of equipment.
The principle of operation of the sensor DKR is to obtain from the converter of the pressure of the electrical signal, the proportional air pressure in the pneumatic system drive rotor wedges. A normalizing amplifier generates the value of this signal to the standard range.
The DSC sensor consists of a tensore pressure transducer, a normalizing amplifier, and a mounting kit. The air pressure in the pneumatic system of the rotor wedges is transmitted to the membrane of a tensoelectric converter without the use of a medium distributor.
In order to reduce the influence of the vibration of the injection line, the normalizing amplifier is executed in a separate housing and connected to the DKR sensor through a cable with a connector connector. All components of the DKR sensor are made of stainless steel.
