In 1983, Honeywell introduced the first Smart Pressure Transmitter:  the ST 3000®. In 1989, Honeywell launched the first all digital, bi-directional protocol for smart field devices. Today, its ST 3000 Series 900 Flange-mount Pressure Transmitters continue to bring proven “smart” technology to a wide spectrum of pressure measurement applications. Flange-mount transmitters are offered with a variety of tank connections including ANSI flanges and sanitary. Applications include gauge pressure measurement in pressure vessels in the chemical industry as well as level applications in both the chemical and hydrocarbon processing industries with either wet or dry legs on the low side. Versatility is made possible though compound characterization of the meter body as well as the ability to measure a broad range of differential pressures.

The ST 3000 Series 100 Absolute Pressure Transmitters are used in applications in which high accuracy in the vacuum range of pressure is required. This includes low-pressure measurement in vacuum     distillation columns, where energy savings are directly proportional to the vacuum in the column.

HangSi products include Rosemount 1151 pressure transmitter, Rosemount temp transmitter, Rosemount 3051GP Pressure Transmitter, flow transmitter, liquid level meter, flowmeter, flow meter, thermal resistance, thermocouple, level gauge, temperature controller and sensors. The brands we can supply include Rosemount, Yokogawa, Abb, Honeywell, Siemens, etc. We have attained ISO9001:2008 certification. Moreover, we had won a lot of awards. Most of our products are exported to Europe, the Middle East, Asia, and America. Thanks to more than 5 years hard work, we have enjoyed a high reputation at home and abroad.

ST 3000 Series 100 Absolute Pressure Transmitters are available in two variants – In-line (STA12L and STA14L) and Single Head (STA122 and STA140).

STA122/STA12L                0 to 780 mmHgA                    0 to 1,040 mbarA

STA140/STA14L                0 to 500 psia                          0 to 35 barA

The transmitters offer compelling benefits :

Total Accuracy = ±0.0375%

Stability = ±0.01% per year

Reliability = 470 years MTBF

Rangeability = 400 to 1

Lifetime Warranty = 15 years

In addition, the pressure transmitter can be used in a wide spectrum of hazardous environments in perfect safety to provide proven, repeatable pressure measurements.

Users can choose from a range of output communication options, including 4-20mA, Honeywell Digitally

Enhanced (DE), HART (versions 5.x or 6.x) and FOUNDATION fieldbus.
