Technical Specifications

The MDM390 offers detailed and precise specifications to meet diverse application needs:

• Pressure Range: From 0~35kPa up to 3.5MPa
• Accuracy: Ranges from ±0.25% to ±0.5% of Full Scale
• Temperature Features: Operating ranges from -10℃ to 70℃, with compensation from 0℃ to 50℃
• Robust Build: Stainless steel diaphragm and housing with Viton O-ring for durable performance
• Advanced Protection: Rated IP65 for dust and water resistance

Installation and Maintenance

To ensure optimal performance and longevity, follow these guidelines:

• Installation: Install a tri-valve between the measurement point and transmitter for even pressure distribution. Preferably install the transmitter horizontally to maintain accuracy.
• Maintenance: Regular checks should ensure that the range and max static pressure are compatible with the measured pressures. Also, ensure that the pressure in the positive cavity consistently exceeds that in the negative cavity.

Electrical Connections

The electrical setup is straightforward with clearly marked wire connections:

• Black: +IN (Input)
• Yellow/White: -IN (Input)
• Red: +OUT (Output)
• Blue: -OUT (Output)

Ordering Information
