Intrinsically Safe Pressure Transmitter, Types MBS 4201, MBS 4251, MBS 4701 and MBS 4751

  • 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 MBS 4201 and MBS 4251 are Ex ia IIC T6...T4 explosion protected according to the ATEX directive 94/9/EC whereas the MBS 4701 and MBS 4751 are Ex ia IIC T4 explosion protected. Both series come with 4–20 mA output signal, absolute or 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.
