XDB500 Liquid level Pressure Transmitter

Short Description:

XDB500 series submersible liquid level pressure transmitters feature advanced diffusion silicon pressure sensors and high- precision electronic components. They are designed to be overload-resistant, impact-resistant, and corrosion-resistant, while providing high stability and accuracy in measurement. These transmitters are suitable for various industrial applications and media. With a PTFE pressure-guided design, they serve as an ideal upgrade for traditional liquid level instruments and transmitters.

When choosing a location for installation, it is important to consider the following guidelines:

● Easy Operation and Maintenance: Select a location that allows for easy access and maintenance of the transmitter.

● Vibration Source: Install the transmitter as far as possible from any sources of vibration to prevent interference with its operation.

● Heat Source: Choose a location away from heat sources to avoid exposing the transmitter to excessive temperatures.

● Compatibility of Medium: Ensure that the measuring medium is compatible with the structural material of the transmitter to prevent any chemical reactions or damage.

● Unobstructed  Pressure Inlet: The measuring medium should not block the pressure inlet of the transmitter, allowing for proper measurement.

● Interface and Connection: Verify that the field interface matches the product interface, considering the connection method and thread type. During the connection, tighten the transmitter slowly, applying torque only to the pressure interface.

● Installation Direction: For input-type liquid level gauges, the installation direction should be vertical downwards. When used in moving water, ensure that the flow direction of the pressure sensitive surface of the transmitter is parallel to the water flow. The measuring medium must not block the pressure hole of the transmitter.

● Careful Handling: When installing the input liquid level timer, handle it gently without forcefully pulling the cable or using hard objects to squeeze the transmitter diaphragm. This is to avoid damaging the transmitter.
