In the pharmaceutical industry, the measurement of pharmaceutical solutions plays a major and important role. The accuracy of the measurement is directly related to the quality of the medicine, and the suitability of the measuring instruments is directly related to the composition and content of the medicine. The pulsed radar level meter uses contactless radar […]

Firstly, the data display is inaccurate. There are actually many reasons for such a fault. For example, a sudden power failure occurs before the data has finished being stored, which in turn leads to an abnormal data display. The first thing we should do in this case is to re-check, reset and calibrate the radar

1. Lightning protection starts with grounding fractions. The housing of the radar level meter is very similar to the control cabinet, special console, power cabinet, etc. The housing should be adjacent to the common flat steel. The instrument task power supply, e.g. 24 V negative terminal, is connected to the instrument earth and the input

We first need to understand the measurement principle of the radar level meter, the radar level antenna emits a narrow microwave pulse, which is transmitted downwards by the antenna. When the microwave touches the surface of the measured medium, it is reflected back and received again by the antenna system, which transmits the signal to

Dust Protection In the external to the instrument dust is very simple, only need in the radar level meter external plus a layer of protective cover or placed in a sealed box, you can maximize the protection of the instrument, for the measured medium contains dust, impurities and particles, such protection measures. In addition to

The radar level meter uses microwave pulse measurement and can operate normally in the industrial frequency band with low beam energy. It can be installed in a variety of metallic and non-metallic vessels or pipes for non-contact continuous level measurement of liquids, slurries and granular materials. It is suitable for applications where dust, temperature and

● Interference problem: Ask the instrument if there is an external power supply, if there is, remove both the external power supply and the signal line, and observe if it is zeroed with battery power only, if it is zeroed, there is interference and the interference measure that GND is connected to the case ground.

The pressure range selection is large, and the small field pressure cannot be collected. The pressure calibration parameters in the instrument have been restored to the factory settings (if the factory is restored, the voltage value in the P21-P25 screen will be 0.0) and need to be re-implanted. The D2 model is slow in collecting

If the temperature display is abnormally high when the battery is powered, the battery is dead. If the temperature display is below zero or much lower, the circuit board temperature chip is damaged and the board should be returned to the factory or a replacement board should be issued. Use a multimeter to measure the

● Since D2 is a dual power supply, to determine whether 24V is properly powered, unplug the battery or test with a multimeter. ● Pulse equivalent post terminal dial code 1 to ON, 2, and 3 to OFF. ● Pulse active output, whether PNP type is matched with the site. ● Measure the voltage between
