MBS4201 & MBS4251 Pressure Transmitters

 MBS4201 Pressure Transmitters

The intrinsically safe pressure transmitter program is designed for use in hazardous environments and offers a reliable pressure measurement, even in harsh applications with severe medium influences like cavitation, liquid hammer or pressure peaks. 

The flexible pressure transmitter program is EEx ia llC 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, and a high degree of EMC/EMI protection equip the pressure transmitter to meet the most stringent industrial requirements.


  • Ex ll 1G EEx ia llC T4 – T6 in compliance with ATEX 100a
  • Applicable in potentially explosive atmosphere: Zone 0, Zone 1, Zone 2 (gases and vapour)
  • Enslosure and wetted parts of acid-resistant stainless steel (AISI 316L)
  • Pressure ranges in relative (gauge) or absolute from 0 up to 600 bar
  • Output signal: 4 – 20 mA
  • A wide range of pressure connections
  • Temperature compensated and laser calibrated
  • MBS 4251 with integrated pulse snubber for protection against cavitation andliquid hammering
