MEP5 Safety Pressure Gauge – with Stainless-Steel Connection

Baumer’s safety pressure gauge MEP5 is specially designed for use in corrosive atmospheres and fluids.

• Designed for use in corrosive atmospheres and fluids
• Measuring ranges from -1…0 to 0…1600 bar
• Thermal drift ± 0,4 per cent for a variation of ±10°C
• With protection class IP67, S3 Safety, and Lloyd’s Register Approval

The gauge has a diameter of 100 mm and can measure pressures from -1..0 to 0..1600 bar at gauge working temperatures of -20..70 °C. The MEP5 has a stainless-steel housing, sensing element, and fully welded process connection. It complies with protection class IP67. A baffle wall and a blow-out back prevent the operator from risk of injuries in case of failure of the sensing element. The MEP5 contains a special compensating diaphragm which maintains accuracy by equalising internal and external atmospheric pressures. Thanks to its robust design, the MEP5 is particularly suitable for applications in the chemical industry as well as use in heavy vehicles, energy production, and oil and gas plants such as the French TOTAL refinery. Special versions with connection sizes specified by the customer are available upon request. This prevents leakage and allows the correct positioning of the measuring instrument.
The thermal drift of the MEP5 is ± 0.4 per cent for a variation of ± 10 °C in relation to the reference temperature 20 °C. The gauge may be used on transient fluid temperatures of up to 200 °C providing that the temperature of the gauge itself does not exceed 70 °C.
The MEP5 boasts an accuracy class of 1 according to European norm EN 837-1 and is available with 22 mm square G1/2 or 1/2NPT process connections. Its window is made of safety laminated glass 4 mm thick. Optionally, the watertight gauge can be filled with a dampening fluid. The MEP5 conforms to S3 Safety as defined by European norm EN 837-1 as well as to Pressure Directive PED 97/23/CE and has a Lloyd’s Register Approval certificate.

Monday, 15. February 2010

With the PBSN product, Baumer is introducing a new general purpose pressure transmitter series. Thanks to their modularity, the devices offer a high level of flexibility to suit customers’ exact application needs. The sensor, which is based on Transbar technology with a thick film ceramic measuring cell, is also suitable for applications with aggressive media. The Baumer FlexProgrammer enables the transmitter’s easy configuration.

• Modularly constructed
• Thick film ceramic measuring cell
• Measuring range from 0..1 bar up to 0..600 bar
• Easy configuration with the FlexProgrammer 9701

Modularly constructed, the PBSN pressure transmitter series offers a flexible design to suit different customer needs, ensuring that their pressure measurement applications are solved with an accurate, reliable and cost-effective product. The Transbar technology-based measuring cells are suitable for gauge as well as for absolute pressure and cover a measuring range from 0..1 bar up to 0..600 bar. The standard accuracy is at 0.7%, or optionally 0.5%, of the full scale.

The thick film technology is based on a ceramic support material for the pressure measuring cell. This material is chemically neutral and compatible with most media, including very aggressive ones. These measuring cells are also characterised by excellent long-term stability and outstanding measuring performance in terms of linearity and hysteresis.

A 4..20mA output signal or voltage output signals are available and all common electrical connections and cable types are offered. PBSN transmitters are delivered programmed according to exact customer requirements, or they can easily be re-configured using the Baumer FlexProgrammer 9701 hand-held communicator tool. The PBSN can be delivered with different process connections made of stainless steel. Moreover, a wide range of gasket ring types (NBR, EPDM, FKM, FFKM, CR and more) are available.

The PBSN is constructed using a fully-welded stainless steel housing with a standard IP65 rating, with IP67 available, depending on the type of electrical connection. It is abrasive and chemically resistant which makes it suitable for numerous general purpose industrial applications in the sectors of pneumatic, chemical and petrochemical, energy production, HVAC and automobile industry.

EN | Baumer | Bourdon – The Original by Baumer

Published on Apr 24, 2014

More than 160 years ago Eugene Bourdon patented his famous invention, the Bourdon tube. Over the years Bourdon’s measurement principle became very well accepted, and the name Bourdon established itself as a synonym for pressure gauges all over the world. Today many companies produce and sell manometers, but only Baumer produce under the original brand. Baumer still continues to manufacture the famous Bourdon tube adding on modern production and quality methods.

The fully welded versions are available with an accuracy of up to 0.1 % F.S. The total error band is less than 0.4 % F.S. over the whole compensated temperature range. The transmitter can be easily configured with the FlexProgrammer.

As part of the modularly designed PB series, which can be adapted individually to customer needs, the PBMN is the high-end transmitter for demanding applications. Thanks to the seal-less construction, the measuring device can be used in many different media. The PBMN is suitable for measuring ranges from 0..100 mbar up to 0..1600 bar. It is based either on piezoresistive technology (for pressures below 40 bar) or on metal thin film technology (for pressures over 40 bar).

The PBMN features a high overpressure resistance and long-term stability (0.1 % F.S.) as well as a very high accuracy over the compensated temperature range from -40 °C up to +85 °C. It is available with accuracies of 0.1 %, 0.25 %, or 0.5 %. The total error band in the compensated temperature range is less than 0.4 % F.S. for the version with 0.1 % accuracy.

The measuring device is provided with several output signals (4..20mA, 0..10VDC, 0..5VDC) and stainless steel process connections. A number of options are available for the electrical connection as well. The PBMN is delivered programmed according to exact customer requirements, but it can easily be re-configured using the Baumer FlexProgrammer 9701. The measuring range is one of the adjustable parameters, and the zero point can be recalibrated as well.

Process Instrumentation – Pressure transmitters PBSR for Railway Applications

Thursday, 9. September 2010

With the PBSR, Baumer’s PB series includes a new pressure transmitter suitable especially for railway applications.

• Wide compensated temperature range from -50 °C to +85 °C with a total error band of only 1 %
• High dielectric insulation (1000 V, 50 Hz, 1 minute)
• Suitable for hydraulic and pneumatic brake control or cooling circuits
• High voltage environments: pressure control of the pantograph on the power supply line

It features a wide compensated temperature range from -50 °C to +85 °C with a total error band of only 1 %. Therefore, it can also be used in braking systems of trains at very low ambient temperatures. Thanks to the high dielectric insulation (1000 V, 50 Hz, 1 minute) the transmitter does not need to be dismounted for dielectric tests on the train.
The PBSR is especially suitable for applications in which the pressure sensors are submitted to many pressure cycles, such as hydraulic and pneumatic brake control or cooling circuits. It can also be applied in high voltage environments, such as pressure control of the pantograph (a device that collects electric current with up to 2’500 ampere from overhead lines) on the power supply line. The pressure measuring range can be selected according to the application. For example, in pneumatic braking systems in trains, it ranges from 0 to 10 bar, in hydraulic braking systems in trams, it ranges from 0 to 250 bar, in cooling systems from 0 to 2.5 bar and in pantographs from 0 to 6 bar. The PBSR comes with a G1/2” process connection and a DIN43650 electrical connection. The device conforms to all important standards for railway applications, such as EN50155 (Electronic Equipment Used on Rolling Stock), CEI IEC 61373 (shocks and vibration), EN 50121-3-2 (electromagnetic compatibility) as well as the fire and smoke protection standards.
