DMD 341 — silicon cell and low differential spans

DMD 341’s listed 6–1,000 mbar options and version-dependent 0.35%, 1% or 2% FSO accuracy must not be merged into one universal performance specification. A silicon sensing element requires the specified port/process media compatibility; do not automatically treat it as a wet/wet industrial transmitter like DMD 331. For filter monitoring or fluid differential, check common-mode pressure, tubing and the desired analog output at the selected low span.

DMD 341 — silicon low-pressure differential gas transmitter: technical profile and specification boundaries

Original BD|SENSORS catalogue differentiates calibrated pressure ranges, media and approval tiers. A family range and optional certification must not be confused with the ordered device.

Parameter Original maker statement Practical selection note
OEM medium Non-aggressive gas and compressed air Do not choose this silicon design for liquid-wetted differential service as with DMD 331.
Full-scale selection 0–6 mbar to 0–1000 mbar ordered portfolio A 6 mbar sensitive cell and 1000 mbar cell are distinct.
Accuracy tiers 0.35%, 1% and 2% FSO depending on ordered sensor option No family-wide 0.35% claim is valid for lower-accuracy versions.
Physical sensor Piezoresistive silicon with compact aluminum case Pressure ports and tube fittings need careful dry-gas routing.
Analog electronics 2-wire current or 3-wire voltage alternatives per BD catalogue Select compatible PLC analog input and transmitter supply.
Pressure connections G 1/8-inch inner threads or tube nozzle options by version Tube size and line leakage affect small differential readings.
Safety certification Manufacturer catalogue shows CE and UL icons for relevant variants UL listing is not automatically an Ex-zone ATEX declaration.

Application engineering and commissioning

DMD 341 makes sense for gas-only differential ranges such as fan airflow/clean compressed gas pressure, but a 2%FSO device at 1000 mbar can have ±20 mbar full-scale-class uncertainty; for a 6 mbar process pressure drop that is unacceptable. Choose the right calibrated pressure cell instead of relying on software scaling. Check response, media cleanliness, common-mode pressure, zero-offset after mounting, correct tubing polarity and thermal gradients. Manufacturer’s aluminium case does not make the instrument suitable for open washdown or corrosive liquids.
