Pressure Transmitter
1.Pressure Transmitter Honeywell STA745 easily meets the most demanding application needs for pressure measurement applications.
2. Honeywell’s Absolute Pressure Transmitters STA740 is a high-performance absolute pressure transmitter with advanced sensor technology. The STA700 provides extremely high measurement accuracy and stability over a wide range of static pressure and temperature by combining absolute pressure with static pressure and temperature compensation on the sensor chip.
3. The STA700 Absolute Pressure Transmitters are available in two variants – In-line (STA7XL) and Dual Head (STAXX) – in the following ranges:
-
STA722/STA72L 0 to 780 mmHgA (0 to 1,040 mbarA)
-
STA740/STA74L 0 to 500 psia (0 to 35 barA)

Description
Honeywell’s SmartLine ST 700 Absolute Pressure Transmitters (STA700) are targeted at applications requiring robust performance in the vacuum range of pressure. This includes low-pressure measurement in vacuum distillation columns, where energy savings are directly proportional to the vacuum in the column.
- Communications/Output Options:
Honeywell Digitally Enhanced (DE)
HART ® (version 7.0)
FOUNDATION™ Fieldbus
All transmitters are available with the above listed
communications protocols.
