At MeasureX, we provide pressure transmitters that are made with quality parts and feature high accuracy to deliver high volumes. These pressure transmitters are especially designed in order to help sustain the performance of industrial plants. 

Our low power pressure transmitters are designed for a variety of applications and include the MRB21 with 3V to 20V power supply and 2.5V output. MeasureX uses a detailed quality management system based on ISO 9001 to ensure that our products meet the highest standards. Here are the features and applications for the MRB21 General Purpose Pressure Transmitter.

MRB21 Features

The MRB21 series General Purpose Pressure Transmitter is silicon-based Piezoelectric pressure transducer, provides flexibility and reliability for a variety of applications. MRB21 is designed especially for use under harsh conditions and remote monitoring systems. Featuring an SS316L diaphragm, the MRB21 offers a compact and rugged design that makes it ideal for a variety of applications. The features of the MRB21 include high measuring accuracy and pressure measurement range of -1 to 600bar. The MRB21 also features reverse polarity and transient current protection.


The diaphragm materials of the MRB21 are made from SS316L, with available option of Titanium, Hastelloy or Tantalum for corrosive Medias upon request.

Standard and Optional Precision

For this device the standard total band accuracy (includes non-linearity, Hysteresis and repeatability) is 0.5% FS. However, other options for a precision of 0.25% FS and 0.1% FS are available.

Temperature and Insulation Specifications

The temperature and insulation specifications for the MRB21 General Purpose Pressure Transmitter are the following:

  • Compensated temp. range: 0 to 70°C
  • Operating temp. range: – 30 to +80°C
  • Temp. coefficient of zero: 0.02% FS /°C
  • Temp. coefficient of span: 0.02% FS /°C
  • Insulation resistance: 100MΩ @ 50VDC

Protection Levels

The MRB21 General Purpose Pressure Transmitter also offers protection levels of up to all around IP65 with DIN connection or the optional IP68 with cable connection. With these customisable features available, the MRB21 is designed for long term application.

Applications of MRB21

The MRB21 series General Purpose Pressure Transmitter is designed for use in portable applications, such as agricultural machinery and water management systems. This is made possible by the 3 to 20VDC input voltage. The MRB21 series can also be used in the pressure measurement of gases & liquids compatible with SS316L.

Other applications for the MRB21 include:

  • Water treatment plants
  • Compressed air line
  • Air conditioning
  • Agricultural equipment
  • Hydrology research
  • Open cut mining
  • Hydrostatic level control
  • Hydraulic pumps
  • Production machinery
