SLT-08A-B Nuclear Medicine Decay Pool Control System

summary:

The radiation monitoring module adoptsThe SLT-08A-B instrument is a new type of online continuous measurement and alarm device for x/γ radiation. The host uses a 32-bit high-speed embedded microprocessor and a 1024x600 color LCD touch screen. The probe is designed with an IP68 waterproof structure and can be used for radiation monitoring in decay tanks. The host and probe adopt a reliable RS485 communication method, ensuring that the host can display the specific dose rate of each probe in real time and indicate the current status of the probe (online/offline/alarm) in real time. The display interface is beautiful and easy to operate.

The module is mainly used forThe measurement and alarm of dose rate using X or gamma rays are widely used in radioactive waste storage, industrial non-destructive testing, hospital gamma knife treatment, isotope application, gamma irradiation, hospital X-ray diagnosis, cobalt treatment, nuclear power plants, decay pools and other radioactive sites.

Water pump control module

The water pump control module adoptsThree or more intelligent controller hosts for water pumps, each controlling the water pump switches of three or more decay tanks. The intelligent controller of the water pump is based on microcomputer microcontroller technology, which integrates motor comprehensive protection and digital display functions. Its unique current and water level induction technology can achieve dual protection for water pump dry running and locked running due to water shortage.

The intelligent controller of the water pump can be connected to five types of control components: pressure transmitter, remote pressure gauge, electrical contact, float, and probe. In the application of decay pools,Considering the use of float level switches for sediment control in the first decay tank, dry reed level switches are used in the second and third decay tanks to achieve automated and intelligent control of the decay tanks.

Functional Features

1. Power on: Connect the power and select the desired control mode - water level control or pressure control.

2. Set current protection parameters: After starting the water pump, the current screen will display the actual working current of the water pump; Set the overload protection and no-load protection to the appropriate protection range, and the current range can also be automatically set through the one click setting function (manual setting is recommended).

3. Choose between automatic and manual working modes (switch with buttons):

4. Fault alarm: After the water pump is protected and stopped, an alarm will be issued, and the corresponding fault indicator light will be on;

5. Overvoltage protection: When the power supply voltage exceeds or falls below the voltage protection range, the power will be automatically cut off within 3 seconds.

6. Overload protection: The more the set value is exceeded, the faster the overload protection action will be.

7. No load protection: It has the characteristic of inverse time limit protection, that is, the more it is lower than the set value, the faster the no-load protection action will be.
