266HSH Differential Pressure Transmitter
Part number 266HSH
High-overload, high-static differential pressure transmitter, ±0.04 % accuracy, 4–20 mA HART, SIL2/3, for DP flow and level.
- CE
- ATEX
- IECEx
- SIL3
- RoHS

Overview
The ABB 266HSH is the high-static-pressure differential transmitter of the 2600T family, used where DP measurement sits on a high-pressure line: feedwater and steam flow with orifice plates, filter monitoring, and level in pressurized vessels. It withstands static pressure to 413 bar, offers turndown to 100:1 and through-the-glass local configuration, and is SIL2/3 certified for safety loops. The 266HSH is an ordering family — span, process connection, diaphragm material and approvals are defined in the full code.
Key features
- Differential pressure spans from 6 mbar to 160 bar, static pressure to 413 bar
- Reference accuracy ±0.04 % of span, turndown up to 100:1
- 4–20 mA HART; PROFIBUS PA and FOUNDATION Fieldbus options
- SIL2/3 per IEC 61508, ATEX/IECEx intrinsically safe and flameproof
- Through-the-glass (TTG) configuration without opening the housing
Typical applications
- DP flow with orifice plates and venturis
- Level in pressurized vessels
- Filter differential monitoring
- Boiler feedwater and steam systems

Frequently asked questions
Is the 266HSH available from stock, and what is the lead time?
Availability of the 266HSH Differential Pressure Transmitter changes with manufacturer production and distributor stock, so we confirm it per request rather than publishing a number that may be out of date. Send the part number and quantity through the quote form and you will receive stock position and lead time within one business day.
Is the 266HSH genuine, and what documentation comes with it?
We supply only genuine ABB products sourced from the manufacturer or authorized distribution channels. Each delivery includes the commercial invoice and packing list; a Certificate of Conformance, declaration of conformity and country-of-origin statement are provided on request, and the manufacturer's warranty applies.
Can you ship the 266HSH outside Vietnam?
Yes. We quote EXW Hai Phong, FCA/FOB, CIF or DAP and prepare the export documentation. Buyers in Japan, ASEAN, Europe and North America regularly consolidate multi-brand orders with us into one shipment.
What if the 266HSH is the wrong variant for my application?
Tell us the application in the notes field. Our engineers check the ordering code against your supply voltage, I/O, communication and environmental requirements and propose the correct variant or a successor part before quoting — at no charge.
