ABB-Absolute pressure transmitter with remote diaphragm seal PAD100
Overview
The ABB PAD100 is an absolute pressure transmitter with a remote diaphragm seal, engineered for demanding industrial pressure monitoring where the process media is too aggressive, viscous, or hot for direct sensor contact. The remote diaphragm seal system physically isolates the pressure sensor from the process, transmitting pressure through a fill fluid instead – the defining distinction between the PAD100 and a direct-mount transmitter like the sanitary PAF100.
Seven Star LLC supplies the ABB PAD100 to chemical, oil and gas, power, and pharmaceutical operators across Oman and the wider GCC as an authorized partner for genuine ABB instrumentation. Every unit is sourced through ABB’s official channel, supported by manufacturer documentation and warranty, and backed locally with diaphragm-seal selection guidance for specific process media.
Operating Principle
The remote seal prevents direct media contact with the pressure sensor, protecting it from corrosion and thermal stress while maintaining fast response times and excellent repeatability – the seal transmits pressure hydraulically through a fill fluid in a capillary line, so the sensor itself never touches the aggressive or high-temperature process media. This remote-mounting capability is essential where the harsh media or physical inaccessibility of the measurement point would make a direct-mount transmitter impractical or unsafe to service. Accuracy extends to 0.075% of span with a 20:1 turndown ratio, and the measuring range spans from 3 mbar (1.2 inH2O) to 100 bar (1450 psi), available in both gauge and absolute pressure versions on the same platform.
The fully welded, robust design is available in a wide range of wetted seal materials matched to the specific corrosive or high-temperature service the PAD100 will see – 316L stainless steel, Hastelloy C276, Hastelloy C2000, super duplex UNS S32750, Inconel 625, Monel 400, tantalum, or PFA (Teflon)-coated stainless steel, with gold-plated and nano-treated (Diaflex, H-Shield) diaphragm options for the most demanding sour or abrasive media.
Engineering Design of the ABB PAD100
With HART communication and optional digital protocols, the PAD100 integrates seamlessly with DCS or PLC systems, making it well suited to modern process automation. Its modular architecture ensures easy calibration, diagnostics, and configuration, reducing downtime and maintenance costs compared to a fixed, non-modular design.
A wide selection of diaphragm seal types – including flanged, threaded, or hygienic options – gives the PAD100 the adaptability to install in tanks, pipelines, or reactors where space, cleanliness, or process integrity are critical factors, letting engineers match the seal geometry to the specific vessel or line rather than compromising the installation.

Industrial Applications
The PAD100 is particularly suitable for chemical, oil and gas, power, and pharmaceutical industries where remote mounting is essential due to harsh media or inaccessible installation points – process taps carrying corrosive chemicals, high-viscosity fluids, or media too hot for direct sensor contact.
Across Oman’s petrochemical and power generation sectors, and throughout the wider GCC, Seven Star LLC supplies the PAD100 as an authorized ABB partner to facilities in Muscat, Sohar, and Salalah that require dependable, factory-genuine remote-seal pressure transmitters with full local support, correctly matched between capillary length, seal material, and fill fluid for the customer’s actual process media.
