The XDB502 liquid level sensor probe is a highly accurate and reliable pressure sensor that can be used in industrial process control, petroleum, chemical, and metallurgical industries. Its pressure-sensitive core uses a high-performance silicon pressure-resistance filling body. The internal specialized integrated circuit converts the sensor millivolt signal into a standard transmission current signal that can be easily connected to a computer interface card, control instrument, intelligent instrument, or PLC.
The XDB502 liquid level sensor probe has various technical specifications, including a working temperature range of 0℃ to 85℃, an accuracy of ±0.5% FS, a compensation temperature range of 0℃ to 60℃, a temperature drift of 2% FS (0℃ to 60℃), an insulation resistance of 50MΩ/250V, and multiple electrical protection levels. The 4-20mA non-polar connection makes it easy to integrate into existing systems.
The installation of the XDB502 liquid level sensor probe is straightforward. The installation location should be easy to operate and maintain, away from vibration sources and heat sources. For insertion-type liquid level sensors, the metal probe should be submerged in the container's bottom. For liquid level probes placed in water, it is best to fix them and keep them away from the water inlet.
The XDB502 liquid level sensor probe comes with a calibrated zero point and full range, and no user adjustment is required. However, if zero point and full range deviation occur during use, calibration can be performed at least once a year, using a pressure source with higher accuracy. The specific method is to adjust the zero potentiometer (Z) to make the current output 4.000mA at the lower pressure limit and adjust the gain potentiometer (S) to make the current output 20.000mA at the upper pressure limit. Repeat this process several times until the sensor's accuracy meets the requirements.
To ensure safe use, it is essential to follow certain precautions. For example, do not touch the isolation diaphragm in the transmitter's pressure inlet with foreign objects. Strictly follow the wiring method for electrical connections, as wiring errors can damage the amplifier circuit. Do not lift the product with wires when installing an insertion-type liquid level sensor. Regularly clean the probe to prevent blockages, and take protective measures for the specially made waterproof wire to prevent wear and tear, piercing, and scratches during installation and use.
In conclusion, the XDB502 liquid level sensor probe is a highly accurate and reliable pressure sensor suitable for industrial level monitoring. Its robust design, high accuracy, and multiple electrical protection levels make it an ideal choice for various industrial applications. With proper installation, calibration, and maintenance, the XDB502 liquid level sensor probe can provide long-term, accurate, and reliable level measurement.
