Supported Applications
The MM Series are micromachined-silicon modular pressure sensors from Omega, designed for industrial, test-and-measurement and aerospace applications. They use micro-machined piezoresistive technology with strain gages embedded in a stable silicon wafer, which gives high-accuracy, high-temperature performance across a very wide span of pressure ranges, electrical outputs and process terminations.
Because the series is highly configurable, a single platform covers gage, absolute, differential, vacuum, compound and barometric pressure measurement. Wetted parts and housing are 316L stainless steel, making the sensors compatible with a broad range of media, and sanitary process connections plus 3-A Sanitary compliance extend their use into hygienic processes. Free OMEGASOFT software is included for USB models.
Operating Conditions & Performance
Measurement spans run from 25 mbar to 350 bar, covering low-pressure ranges quoted in inches of water through high-pressure ranges to 5000 psi. Accuracy is specified on a best-straight-line (BSL) basis and is available from ±0.05% FS through ±0.08% FS, ±0.20% FS and ±0.40% FS depending on configuration, with a response time of < 1 ms.
Output options include a mV output (10 mV/V), 4 to 20 mA, 0 to 5 Vdc and 0 to 10 Vdc, along with a USB output. Excitation and power range from 5 to 10 Vdc for ratiometric outputs up to 10 to 30 Vdc @ 10 mA, and the 9 to 30 Vdc supply derates to 9 to 20 Vdc above 229°F. The sensors operate over a process temperature range of -45 to 121°C and an ambient range of -15 to 115°C, and carry IP67 or IP65 protection.
Each sensor measures ø22.25 mm (0.88 in) in diameter by 60.97 mm (2.40 in) in length and weighs 115 to 200 g depending on configuration. The line is CE and RoHS compliant and NIST traceable, and withstands 50 g, 11 ms half-sine shock.
Configuration Options
Every MM sensor is built to order, so variants differ by the options selected in the part-number configuration rather than by fixed model tiers. The main axes of variation are:
- Pressure type and range — gage, absolute, differential, vacuum, compound or barometric, spanning 25 mbar to 350 bar.
- Accuracy — selectable BSL accuracy from ±0.05% FS to ±0.40% FS.
- Output — mV, 4 to 20 mA, 0 to 5 Vdc, 0 to 10 Vdc or USB.
- Electrical termination — cable, Mini DIN, twist-lock, M12 connector or USB.
- Process connection — 1/2" NPT, 1" NPT, 1 1/2" or 2" Tri-Grip™, or 1 1/2" and 2" sanitary fittings.
Optional adjustable zero and span potentiometers and a secondary fluid containment system further tailor each unit. Bidirectional differential models are calibrated in the positive direction only.
Key Product Differences
Sensors are ordered as a configuration string that encodes the pressure range, output, termination, connection and options. Representative configured part numbers in the series include:
- MMA1.0KV10P2C1T3A3P
- MMA5.0KC1P4J5T4A3
- MMDWU001C1P4C2T2A1P
- MMDWU001V10P3D0T1A1
- MMG10WV10P4D0T2A2P
- MMV015C1M2C1T3A3
Each string selects a specific combination of the pressure type, range, accuracy, output and termination described above, so the "model" is effectively defined by the customer's configuration rather than by a small fixed catalog.

Transducer works as expected
Signal is stable. Was not clear to me from the data sheet, but the conduit option comes with prepped wire leads.

Can you supply the procedure for testing and verifying the output of the transducer, using the ZERO and SPAN adjustments? We had a NEW unit show zero output after adjusting these...
Thank you for your inquiry, during the final calibration and verification of our sensors we do not use the zero and span adjustments.

Hello, I configured PN MMA015V10P1C1T4A4, 15 PSIA pressure transducer, 0-10VDC output. Please confirm the voltage outputs at 0 PSIA and at 15 PSIA. Thank you
Thank you for your inquiry, the unit that you have configured has an output of 0 to 10 volts at 0 Psia to 15 Psia

I am looking for the burst pressure and code of construction for my configurations of this pressure transducer. One is a MMA750V5P5C1T3A3CE, and the other is a MMA150V5P5C1T3A3CE (the only difference being their rated pressures).
The secondary containment (burst pressure) rating for both the 0 to 750 PSIA and 0 to 150 PSIA range MM Series transducers is 6000 PSIA. Not sure what you mean by code of construction. Are you full specifications of these sensors?

Does the type of DC power supply affect the accuracy? For a 0-10V output would a 15VDC linear supply result in better performance than a 15VDC switching supply?
Voltage transducers and current loop transmitters normally have amplifiers and signal conditioning built in. They can accept an unregulated or regulated power supply, which means the excitation voltage can vary between limits set by the manufacturer and, for a given pressure, the output signal will not vary.
I have personally used regulated and unregulated power supplies, I do not have much experience with switching supplies.

I'm looking for a diff pressure transducer that is able to measure a small pressure differential (i.e <1PSI), but in a high pressure vessel. On the spec sheet, which rating indicates the safe operating range for the device? The line static pressure?
Line/Static Pressure: 500 psi maximum applied to both sides simultaneously...
Proof Pressure (Differential):
10 inH2O range = 10 times range
1 psi range = 6 times range
2.5 to 750 psi ranges = 4 times range
1000 psi range = 3 times range
Hi Side Containment Pressure (Differential):
Ranges 10 inH2O to 5 psi: to 1000 psi
Ranges 15 to 1000 psi: to 3000 psi

I am going to use MMG001C1P3B1T1A2, MMA030C1P1B1T3A4, and MMDWU001C1P3B1T1A2. Does mounting orientation affect any of these transducers?
We would recommend keeping them up, perpendicular to the surface. Especially the 1 psi range for both single and diff. pressures. This is very low ranges and very sensitive to the atmospheric pressures and will affect the performance of them. The 30psi should be ok.
