UsedDeltabar S PMD75 differential pressure transmitter with piezoresistive metal sensor, 4–20 mA HART output and up to 100:1 turn down — ±0.075% accuracy, up to SIL 3. 27 units in Barmaan's warehouse, sold individually: calibrated spans from 0…1 kPa to 0…300 kPa. Each unit has its own photographs and its own nameplate.
The Endress+Hauser Deltabar S PMD75 is one of the most accurate and most widely used differential pressure instruments in the process industries. Barmaan holds 27 of them physically in the warehouse and sells them individually: each unit on this page is a specific physical device with its own order code, its own nameplate and its own photographs, taken in our warehouse. Choose a unit below to see the device you would actually receive.
The units in stock are not all calibrated the same: the factory spans run from 0…1 kPa up to 0…300 kPa, with one unit calibrated in 0…250 mmH₂O, so the range is stated per unit rather than for the page as a whole — the nameplate photograph of each unit shows its own Cal./Adj. plate. Six units were photographed without their main nameplate; their range is available on request. Across the family the span is adjustable and, thanks to the piezoresistive metal sensor, supports a turn down of up to 100:1. Per official datasheet TI00382P the reference accuracy is ±0.075% of the set span (up to ±0.035% in the PLATINUM version), and the maximum static working pressure is 16 MPa (160 bar).
The Deltabar S is not only a differential pressure transmitter: with dp elements (orifice, pitot) it is used for flow measurement, and in pressurized vessels for level and volume measurement; square-root and linearization functions are available on the device itself. The wetted parts are 1.4435/316L stainless steel with an FKM seal, and the housing carries IP66/IP67 ingress protection suitable for industrial installation.
The device output is 4–20 mA with the HART protocol, with an 11.5 to 45 V DC supply. The Deltabar S can be used up to safety integrity level SIL 3 per IEC 61508 (TÜV SÜD approved), benefits from continuous performance monitoring from the sensor through to the electronics, and its HistoROM®/M-DAT memory allows the electronics to be replaced easily while retaining the configuration.
The Deltabar S is part of the uniform Endress+Hauser pressure platform (Deltabar S – Deltapilot S – Cerabar S) and has for years been an industry standard for accurate differential pressure, flow and level measurement in the oil, gas, petrochemical, chemical and power-generation industries.
Barmaan supplies industrial instrumentation; this item is offered with a guarantee of authenticity, the option to inspect it in person at the warehouse, selection consultancy, and installation and commissioning support. To obtain pricing, submit a proforma invoice request from this page. The photographs of each unit are unretouched and show its actual state; a formal condition report on a specific unit is available on request.

Barmaan does not claim these units are new: their condition has not been formally inspected, and the grading on record is «unknown» for all 27. What we can show is the device itself — every unit on this page has its own unretouched photographs taken in our warehouse, so you can see its actual state before you commit. A formal condition report on a specific unit is available on request, as is an in-person inspection at the warehouse. (The nameplates carry no year of manufacture, and none is claimed.)
The range is stated per unit, because the units in stock are not calibrated the same: the factory spans run from 0…1 kPa up to 0…300 kPa, with one unit calibrated in 0…250 mmH₂O. Each unit row lists its own range and order code, and its nameplate photograph is in the gallery. Six units were photographed without their main nameplate; their range is available on request. Per official datasheet TI00382P the reference accuracy is ±0.075% of the set span (up to ±0.035% in the PLATINUM version), and the maximum static working pressure is 16 MPa (160 bar).
No. Besides differential pressure, the Deltabar S is also used for flow measurement (volumetric or mass) together with dp elements such as orifice plates and pitot tubes, and for level and volume measurement in pressurized vessels. The internal calculation functions — square root for flow and linearization for level — are available on the device itself.
Per the nameplate this unit has a 4–20 mA output with the HART protocol and is compatible with all common DCS/PLC systems (Siemens, ABB, Yokogawa, Emerson and others) as well as with HART calibrators and configurators. Its supply is 11.5 to 45 V DC. Other versions of the Deltabar S family also offer PROFIBUS PA and FOUNDATION Fieldbus.
Yes. Per the official datasheet the Deltabar S can be used up to SIL 3 per IEC 61508 (TÜV SÜD approved) and benefits from continuous performance monitoring from the sensor through to the electronics. Its HistoROM®/M-DAT memory also allows the electronics to be replaced without recalibration.
You can submit a proforma invoice request from this page; Barmaan's engineers will confirm the price and delivery terms within one working day at most. The item is in stock, so once the order is confirmed it is ready for collection or shipment with no overseas procurement lead time. Authenticity is guaranteed, and you are welcome to inspect the device in person at the warehouse.
