It is also possible for the Channel partner to customise the electronics including adding a partner address and customer services number.

unit up to handheld HART devices and PCs. The transmitters are also easy to install.
A double-threaded process connection which can be used with a huge range of adapter accessories ensures maximum compatibility by enabling the transmitters to meet the installation requirements of a range of different industries with different locations, environments and requirements. Using ABB’s range of adaptable connectors and flanges, the PxS100 series can be rapidly configured to accommodate hundreds of different requirements.
How has ABB managed to speed up the delivery of the pressure transmitters?
The thing that makes it possible to fit in a variety of settings are the fittings. Options such as interchangeable threaded connectors and flanges enable ABB’s nationwide network of stockists and value providers to stock product without the need to make a bespoke order. This means customers can order a device to their own specific requirements directly from either their value provider or ABB and expect delivery within a few days. The additional benefit is that ABB has

The PxS100 range has been designed to meet the trend for increasing digitalisation and incorporates all sorts of features that make it easy to obtain vital information online. One key feature is the inclusion of QR codes. There is a ‘static’ QR code printed onto the device’s name plate. When scanned using a smartphone or tablet it will give direct access to the PxS100 series webpage where manuals, instructions and any other related documentation can be retrieved. The device can also offer Digital Diagnosis
Access (DDA), using dynamic QR codes which are activated by an error or when a faulty condition is detected, such as the process being outside the measuring limits. Dynamic QR (DQR) codes take the advantages of QR code technology one step further. Unlike QR codes which are static and can only display a limited amount of predefined, hard-coded information, DQR codes are able to reflect the real-time status of the device in question. Scanning the dynamic QR code on the device will bring up diagnostic information, possible causes and instructions on how to correct it all in clean clear and detailed text.
Many customers have issues with arduous process conditions. How does the transmitter solve this?
In the past, maximising protection meant having a top of the line high end pressure transmitter with
costly protective coatings or materials. ABB’s solution to this is diaflex coating.
Diaflex is a flexible diamond coating that provides a comprehensive safeguard against abrasion and other harsh operating conditions that can quickly destroy pressure transmitter diaphragms in unprotected devices. With a Vickers hardness value of 4000HV, it exceeds the resilience of other forms of protective coatings such as gold and ceramics, without compromising pressure transmitter performance. This is due to its ultra-thin thickness, which allows the springiness, or flexing, of the metal diaphragm to be retained, enabling it to be used for applications with process temperatures ranging from -100°C to 700°C depending on the fill fluids being used. The transmitter also features our H-Shield
technology. H-Shield resolves the issue of hydrogen permeation that causes galvanic corrosion in applications with dissimilar metals. If allowed to do so, hydrogen can pass through metal, potentially causing a bubble to form in the pressure transmitter diaphragm that can eventually destroy the transmitter. This issue has traditionally been solved by coating the diaphragm with gold. While effective, this method is very expensive and can be hard to work with. H-Shield overcomes this, by allowing the use
of stainless-steel material with Hastelloy with a protective coating. As well as being less costly, it offers much greater protection than gold, without affecting measurement performance.
Finally, how would you describe the PxS100 range in a nutshell?
The range provides all the features and functions you need. Flexible and adaptable, it gives you the right solution in a fraction of the time normally needed to specify, adapt and deliver a typical pressure transmitter.
