DPT 100 โ differential pressure precision and interfaces
The DPT 100 portfolio spans roughly 10 mbar to 20 bar in manufacturer model options; selecting a high-span cell for a small pressure drop can compromise absolute resolution. Its stated 0.1% full-scale accuracy requires the actual ordered span, reference and calibration conditions. Where Modbus RTU is specified, validate the RS485 cable, address, register mapping and host scaling instead of assuming a purely analog transmitter. Pressure port installation and allowable static pressure need separate checks.

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 |
|---|---|---|
| Pressure type | Differential process pressure between high and low ports | Not a single-port gauge pressure sensor. |
| OEM calibrated spans | From 10 mbar to 20 bar depending on ordered sensor | Do not call every DPT 100 a continuously adjustable 10 mbarโ20 bar device. |
| Accuracy grade | 0.1% FSO according to original family listing | Full-scale accuracy is not 0.1% of reading at low differential pressure. |
| Wetted sensor | Stainless-steel pressure sensing system | Fluid compatibility must be confirmed for process medium and seals. |
| Connectivity | Manufacturer lists Modbus RTU availability for DPT 100 | Physical pin/line parameters and analog outputs depend on actual order code. |
| Safety certifications | OEM family listing does not display the same ATEX/IECEx/HART approval icons as DPT 200 | Do not copy DPT 200 approvals to DPT 100. |
| Use cases | Testing, mechanical and plant engineering | Check common-mode line pressure and overpressure independently from differential span. |
Application engineering and commissioning
DPT 100 is a precision differential model. In filter or process pressure measurement both ports may sit at significant static pressure, so maximum working pressure and overload must be verified independently from 0โ10 mbar cell span. A ยฑ0.1% FSO rating means approximately ยฑ0.01 mbar on a 10 mbar range when its defined conditions apply; compare that with the controller setpoint tolerance and transmitter drift. Establish temperature/pressure compatibility, electrical isolation, correct high/low port orientation, Modbus mapping and exact output mode. This is not interchangeable with DPT 200’s 0.075% grade or its own hazardous-area approvals.
