LABOM intelligent differential pressure transmitterThe measured pressure difference is only equal to the pressure difference at both ends of the throttling element. As the flow rate increases, the pressure difference measured by the differential pressure transmitter will be significantly higher than the pressure difference at both ends of the throttling element, resulting in measurement errors. The hidden orifice plate can have different inner diameters. Set the upper limit of the differential pressure transmitter using a handheld terminal to change the range of the flowmeter. According to the connection method of the pressure tapping port, it can be divided into two types: threaded connection of the pressure guiding pipe and sealed flange connection of the membrane box. The connection method is generally selected based on the medium. Variable frequency drives have been applied in various fields of industrial control due to their energy-saving, energy-saving, and reliable characteristics, and play an important role, such as variable frequency speed regulation in power, textile and chemical fiber, building materials, petroleum, chemical, metallurgy, public engineering, etc.
Generate 24V and positive/negative 15V DC power to supply to the gate control unit circuit board, and detect some fault signals for protection. The gate control unit controls the high-power switching transistor to conduct and turn off by modulating the voltage signal generated. Zui is followed by the interface unit, which includes the interface board and serial interface, mainly used for communication with other devices. When a fault occurs, the line contactor automatically opens, the power supply area discharges, and the corresponding fault alarm is displayed. During long-term use, common faults include the following, and there are corresponding maintenance and handling methods.LABOM intelligent differential pressure transmitterThe delay mechanism is equipped with a manual reset device. When the compressor stops due to the inability to establish oil pressure, the controller cannot automatically reset after action. The reset button must be pressed again after troubleshooting to turn on the motor power supply of the delay switch in the delay mechanism and start the compressor.
