Danfoss 059G0026 MBS 3350 Pressure Transmitter 0-30 bar, Bayonet
Description
MBS 3350: a 0 to 30 bar transmitter with pulse-snubber and bayonet connector
Danfoss 059G0026 is an MBS 3350 pressure transmitter for 0 to 30 bar (0 to 435 psi), sealed gauge, with a 4 to 20 mA output. The process connection is an M18 x 1.5 male thread with a 27 mm hex to DIN 3852-E / ISO 9974-2 (Form E). The electrical connection is a 3-pin bayonet to ISO 15170, and the enclosure rating is IP67. The key printed on the page is MBS 3350-C831-C8BA12-1.
The ratings are an accuracy of 0.5 percent typical (1 percent maximum), a non-linearity of 0.5 percent, a response time of 4 ms maximum, a maximum overload pressure of 180 bar (2611 psi) and a supply of 9 to 32 V DC. The medium range is -40 to 125 C, compensated 0 to 100 C, and the ambient range is -40 to 100 C.

What the MBS 3350 adds over simpler transmitters
The 3350 has an integral pulse-snubber, which damps pressure peaks and water hammer, so it is suited to hydraulic, pump and compressor lines where pressure spikes occur. The 180 bar overload is six times the range, which gives margin for those peaks.
Approvals printed are ATEX (Ex ec IIA T4 Gc), C UL US UL Recognized and CE, but the transmitter is not intrinsically safe. The page also gives the signal clipping limits (3.6 and 22.4 mA), which a controller uses to detect a fault.
Ordering and checks
Check that the M18 x 1.5 male thread and the bayonet plug match your equipment, since that differs from the G 1/4 and the DIN connector on other types in the range.
Confirm range, signal, connector and the Ex requirement before ordering. The installation guide lists wiring for MBS 33, MBS 33M, MBS 3000 and MBS 3050 types, and the data sheet covers MBS 3300 and MBS 3350.
Other types and sizes from the same Danfoss family that appear in the Danfoss store listing include MBS 9200 (064G0013), MBS 9300 (064G0023), MBS 3000 (059G0002), MBS 3300 (059G0008), MBS 3200 (059G0036), MBS 3250 (059G0043), MBS 3050 (059G0046), MBS 33 (060G1222). These are listed for orientation only; each has its own datasheet values, so check size, connection and version before ordering.

About brand
Danfoss is the Danish engineering group that makes refrigeration and air-conditioning controls, heating components, variable speed drives and mobile hydraulics. Mads Clausen founded it on 1 September 1933 at his parents' farm in Nordborg on the island of Als, after making his first refrigeration expansion valve in 1932. Nordborg is still the group's headquarters, and Danfoss remains controlled by the Clausen family through the Bitten & Mads Clausen Foundation.
Danfoss company profile
| Founded | 1 September 1933, Nordborg, Denmark, by Mads Clausen (1905–1966) |
|---|---|
| First product | Thermostatic expansion valve for refrigeration |
| Headquarters | Nordborg, Denmark |
| Ownership | Private; majority controlled by the Bitten & Mads Clausen Foundation and the Clausen family |
| Size | About 42,000 employees (2023) |
| Business segments | Danfoss Climate Solutions (refrigeration, air conditioning and heating), Danfoss Drives (VLT and VACON frequency converters, soft starters), Danfoss Power Solutions (mobile and industrial hydraulics) |

Milestones
- 1932–1933: First expansion valve; the company is founded in Nordborg.
- 1939: 26 employees. By the 10th anniversary in 1943 the company has 179.
- 1950s: Rapid growth turns Nordborg into a Danfoss town with housing and schools for its workforce.
- 1968: Danfoss launches its VLT frequency converter, one of the first mass-produced AC drives.
- 2014: Acquisition of the Finnish drives maker Vacon, now the VACON brand.
- 2021: Acquisition of Eaton's hydraulics business.
Choosing Danfoss products
For solenoid valves, check the operating principle. A direct-operated valve such as EV210B opens even at 0 bar differential pressure. A servo-operated valve such as EV220B needs a minimum differential (typically about 0.3 bar) to open, while an assisted-lift valve such as EV250B works from 0 bar. Coils are ordered separately, so the voltage on the coil (for example 230 V AC or 24 V DC) must match the control circuit. For drives, the VLT family is split by application: FC 51 Micro Drive for small machines, FC 102 HVAC Drive for fans and pumps in buildings, FC 202 AQUA Drive for water, and FC 302 AutomationDrive for demanding industrial duty.
Where Danfoss products are used
In Oman and the GCC, Danfoss drives run pumps, fans and compressors in district cooling plants, water and wastewater stations, desalination and building HVAC. Danfoss pressure switches, transmitters and solenoid valves are built into chillers, refrigeration plants, boilers and hydraulic systems, and AB-QM valves balance chilled-water circuits in large buildings.

Ordering Danfoss products: what we need
Send the Danfoss code number from the label (for example 032U7115 or 131B0149) or the full drive type code (FC-302P3K0T5...). For drives, add the motor power, supply voltage and any fieldbus option. For valves, add the size, connection, medium and coil voltage. For pressure switches and transmitters, add the range, output and pressure connection.
