Working principle of pollution transmitter

The working principle of the pollution transmitter is relatively simple but efficient, and its core lies in monitoring the blockage of the filter element. The following is a brief introduction to the working principle of the pollution transmitter:
The pollution transmitter is usually installed on the filter of the hydraulic system to monitor the degree of blockage of the filter element by impurities and particles in the oil. When the hydraulic system is working, the oil passes through the filter, and the filter element will trap these impurities, causing the filter element to gradually clog. This blockage will result in a pressure difference between the inlet and outlet of the oil, which is the pressure loss of the filter element.

The pollution transmitter is equipped with a sensor inside to sense this pressure difference. When the pressure difference increases to a certain extent and reaches the preset alarm value of the transmitter, the sensor will trigger the alarm mechanism. This alarm mechanism can be an optical signal (such as an indicator light on) or an electrical signal (such as turning on a relay to emit an electrical signal).
Once the transmitter sends an alarm signal, the operator can promptly detect the blockage of the filter element and take corresponding measures, such as cleaning or replacing the filter element. This can ensure the normal operation of the hydraulic system and avoid system failures or damage caused by clogged filter elements.

In general, the pollution transmitter monitors the pressure difference between the inlet and outlet of the filter and sends an alarm signal when the pressure difference reaches a preset value to indicate the blockage of the filter element, thereby ensuring the safe and reliable operation of the hydraulic system.
