Connectivity and Software

The MDM460 series is compatible with the Setonline software, which facilitates communication via the RS485 interface. This software allows users to display pressure, level, and differential pressure values, perform zero adjustments, manage analog outputs, and set transmitter addresses. The software is available for download from the official Microsensor website, enhancing the overall functionality and ease of use of the MDM460 series.

Ordering Information

When placing an order for the MDM460 series, please specify the desired pressure range, output signal type, construction material, and power supply. The default configuration includes a 24VDC power supply, 0.5% FS accuracy, and no relay control. Custom configurations can be tailored to meet specific application needs.

Important Notes

1. Ensure that the power supply, accuracy, and relay quantity are specified in your order. The default setup is a 24VDC power supply with 0.5% FS accuracy and no relay control.
2. If you require communication software and RS485 interface instructions, please mention this in your order.
3. To avoid overpressure, it is recommended to install a tri-valve between the measured point and the transmitter. This ensures gradual pressure loading on both the positive and negative cavities.
