Pressure transmitters handle R and D demands

An ABB Automation Tech (Instrumentation + Automation) product story
Edited by the Engineeringtalk editorial team Jul 24, 2008

ABB transmitters can be easily configured to operate over different pressure ranges, and can handle testing at 10bar.

Mira is using ABB pressure transmitters in the design of its showers.

Competing transmitters kept failing in this demanding application, but ABB 261 pressure transmitters were able to handle the high pressures and delivered excellent reliability and accuracy.

Mira has a total of ten test rigs at its site in Cheltenham, where it manufactures both mixer and electric showers.

The rigs are used to test new and existing products as part of the company's ongoing development process.

Most of the test procedures involve measuring pressures between 0 and 1bar, but Mira guarantees its products up to 10bar and therefore needs to run some tests at higher pressures.

The Mira electrics team estimated that ten transmitters were being destroyed each year, resulting in regular replacement costs and inconvenience.

The company decided to make the switch to 261 gauge pressure transmitters from ABB.

All the units were sourced through ABB's Instrumentation Alliance partner, AM Sensors.

Paul McLaughlin, Sales Engineer for ABB said "By investing in these transmitters Mira have been able to ensure long-term savings".

The new transmitters never go over 10bar in Mira's tests and that's well below what the ABB transmitters are rated at.

If they can run for just two years without having to replace them then they've saved money".

So far the new transmitters have been running successfully for 12 months without any pressure-induced problems.

For Mira, the other major advantage of the ABB transmitters is that they can be easily configured to operate over different pressure ranges.

The 261GS is the compact transmitter class for gauge pressure within ABB's 2600T series.

It provides a large turndown ratio of up to 20:1.

The compact, robust transmitter housing is made of 316 stainless steel, which provides corrosion resistance for trouble-free operation in a wide variety of process and ambient conditions.

The user-friendly display allows simple and intuitive local transmitter operation, while the transmitter provides local zero and span adjustments, even without the display.
