Danfoss MBS 4701 Pressure transmitters with Eex approval adjustable zero and span

The Danfoss intrinsically safe pressure transmitter MBS 4701 is designed for use in hazardous environments, and offers a reliable pressure measurement, even in harsh and requiring applications.
The flexible pressure transmitter programme is EEx ia IIC T6 explosion protected according to ATEX 100a and covers a 4-20 mA output signal, absolute and gauge (relative) versions, measuring ranges from 0-1 to 0-600 bar, zero point and span adjustment, plug connection and a wide range of pressure connections.

 

 

 

Excellent vibration stability, robust construction, a high degree of EMC/EMI protection and a high operating temperature, equip the pressure transmitter to meet the most stringent industrial requirements.

• 4 - 20 mA output signal
• Measuring range 0 - 600 bar
• Operating temperature depending on electrical connection
• With zero point & span adjustment
• Ex II 1G EEx ia IIC T4 - T6 in compliance with ATEX 100a
• Applicable in potentially explosive atmosphere: Zone 0, Zone 1 and Zone 2 (gases and vapour)

Millions of cycles, high overpressure and excellent long-term stability
Thanks to an innovative design the pressure transmitters are accurate and reliable, even in extreme environments with high-pressure peaks, vibration and temperature fluctuations.

Laser trimmed electronic circuit in thick film for improved accuracy and low thermal shifting
To ensure a high reproducibility even on different operating temperatures all the pressure transmitters are temperature compensated in the range from 0 to 100°C. Each sensor is individually electronically temperature compensated.

Fully welded sensor: no internal O-rings and all housing and wetted parts in stainless steel (AISI 316L)
When used with aggressive media there is a risk of corrosion of metal parts &attack on O-rings used for sealing. Pressure transmitter types MBS4201, MBS 4251, MBS 4710 and MBS 4751 have fully welded diaphragms and do not therefore require O-ring seals. This hermetic sealing completely removes the risk of leaks. The use of stainless steel for all parts in contact with the media makes the pressure transmitter highly media resistant.

Long term stability and reliability based on the very robust piezo resistive technology
The pressure transmitters use Piezo resistive silicon sensor technology because of its superior measuring performance and high vibration stability. Unlike other sensor technologies, the piezo resistive silicon sensor needs no protection against pressure peaks, in that the pressure overload is typically six times (max. 1500 bar) the measuring range and performs millions of cycles.
The measuring performance of a pressure transmitter can be influenced by moisture entering enclosure and degrading the transmitter electronics The Danfoss pressure transmitters are filled with Silicon based sealing material to protect the electronics against moisture.

High robustness against environmental influences
Excellent vibration stability, robust construction, and a high degree of EMC/EMI protection equip the pressure transmitter to meet the most stringent industrial requirements.
