Relay Seal: Epoxy resin, node capacity DC30V/5A or 220V/5A, single pole double throw
Power-up delay: about 10 seconds
Temperature range: During exercise -25°C～+65°C When storing? 40°C～+85°C
Relative humidity: up to 95%, non-condensing speed monitor, coupled with magnetoresistive sensors, eddy current sensors, hall sensors to monitor the unit speed. The micro-processing chip is used to process the signal, the measurement is accurate, the performance is stable, and the function can be extended according to the needs of the user. Rotary machinery, especially steam turbines, with sudden speed spikes is one of the most dangerous situations that can have disastrous consequences. It is extremely important that the unit can quickly and easily pass critical speeds when the unit is started or stopped. It is of great importance to monitor and protect the rotational speed of rotating machinery in electric power, petroleum and chemical industries. The device is highly intelligent, enabling full-scale board operation, suitable for long-term on-line monitoring, and without on-site maintenance.
The main function
Turbine, turbine, compressor, blower and other rotating machinery shaft speed monitoring and protection.
Function Description:
1. With speed measurement display function, the maximum speed 99999 rev / min, five digital display.
2. The alarm function, when the measured speed exceeds any alarm set value, the corresponding alarm indicator on the front panel is on, and the switch signal is output at the rear panel to protect the monitored equipment.
3. The alarm value, number of teeth, and time can be set via the front panel keys.
4. It has storage function for overspeed events to prepare for queries.
5. Indication of sensor or input circuit faults.
6. With self-test function
7. With voltage and current output interface, it can be connected with computers, DCS, PLC systems, paperless recorders and other devices.
Technical Parameters:
1. Input signal: Magnetoresistive sensor, eddy current sensor, Hall sensor, sine wave or pulse input, input voltage RMS 0.3-20V
Sheet metal fabrication processing is formed by laser cutting or stamping process, shear and bending, bending, bending, welding, riveting. The Sheet metal fabrication used are cold-rolled plate (SPCC), hot-rolled plate, galvanized plate (SHCC) (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (5052), stainless steel. Sheet metal fabrication processing steps: according to the parts drawing (3D) expanded into a plan (2D), laser cutting or die stamping shape, CNC punching each bending part, should pay attention to the direction of the burr of the workpiece. Then the students are welded or riveted (some). Surface treatment after processing: electroplating, passivation, sand blasting (powder), anode treatment. Products are generally made for the connection and the outer cover. Applications in robotics, drone, communications, medical devices, industrial automation equipment.
