ABB Original 266 Series Differential Pressure Sensor Differential
Pressure Transmitter
The ABB 266 is a differential pressure transmitter with
“multisensor technology” suitable for measuring liquid, gas or
steam flow as well as level, pressure and density characterized by
a direct mount seal. This transmitter can be configured with a
direct mount diaphragm seal and a standard pressure connection or
combined with a remote diaphragm seal. Long-term stability and
proven reliability of 266 make it to the best choice for
differential pressure measurement.
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.
