ABB-266DDH Direct-Mount Seal Differential Pressure Transmitter in AI

Overview

This transmitter can be configured with a direct mount diaphragm seal and a standard pressure connection or combined with a remote diaphragm seal. In order to show its flexibility, the 266DDH can be transformed into a gauge pressure transmitter by mean of a dedicated gauge filter for atmosphere reference. Exploit ABB unrivaled leadership in diaphragm seals design and manufacturing: - no thread joints or gaskets that is prone to fail or drift in time - less fill volume to achieve better temperature effects In addition to the plug-in terminal block, this transmitter features in-field replaceable electronics module that thanks to the auto-configuration functionality dramatically improves plant productivity. Its intuitive plug-and-play display with easy setup procedure really helps users by saving time and lowering maintenance and inventory costs. Moreover, the innovative TTG (Through The Glass) technology allow users to configure the instruments in the field without removing the windowed front cover and consequently to save a lot of time. SIL2/SIL3 certification issued by TÜV Nord according to IEC 61508 represents another key-feature within 266 pressure transmitter portfolio. This certification is a real guarantee of protection and makes of 266DDH the smartest fit in Safety-critical loops. 266DDH features WirelessHART communication protocol allowing a shorter installation times by eliminating complex wired infrastructures, and lower overall implementation costs of process measurement. 266DDH battery life is about 10 years at 32 sec. update rates, delivering a very cost effective and reliable solution to monitor your process assets.

How do I determine which instruments I need and their cost?

This depends on what you are needing to control or measure, your operating environment, your specific process flow, and many other factors. Durkin’s process specialists can help you determine the specific process instruments (down to the part number) that suit your application, budget, and expected life-span the best. Call (314) 432-2040 or contact us.

What is process instrumentation?

Process Instrumentation are sensors and instruments used to measure and control process variables including levels, flow, pressure, temperature, pH, and humidity.

In-field instruments, such as flowmeters or temperature sensors, are close to the process or measurement point, or may even have process liquids flowing through them. Panel instruments not usually where the process is happening, but are rather located ina controlled room or with the line controls.

Common types of process instrumentation include: flow meters, rotometers, level sensors, temperature sensors, recorders (to record process data), actuators, valves, gas analyzers, positioners, and actuators.

What symbols are used for process instruments?

Depending on the program, plant standards, and engineering firm that did the drawings, symbols for process instrumentation can vary. You should have been supplied with a lead or legend sheet that defines the symbols for the particular set of drawings you are looking at. However, there are a common set of generally agreed upon symbols, examples of which you can reference here.

Robert Cook at AiCHe has put out an excellent blog post on interpreting and using instrumentation symbols. If that doesn’t help, contact Durkin and one of our team members can help you solve the mystery: (314) 432-2040

Do you only supply the brands listed?

We carry a wide-range of process instrumentation and solutions. You can see our full supplier list here, but we may be able to source brands or point you the right distributor for other brands. More importantly, we can help you determine the appropriate instrumentation and controls solutions needed to solve your process issues.
