Rosemount 1199 teletransmission diaphragm level transmitter

I. Instrument overview:

Rosemount 1199 teletransmission diaphragm level transmitter can be assembled on Rosemount 3051S, 3051, 1151. and 2088 differential pressure, gauge pressure and adiabatic pressure transmitters and level transmitters. Rosemount 1199 remote transmission diaphragm system provides a wide range of products and specifications worldwide, to meet the requirements of various measurements and applications.

II. Working Principle:

When the Rosemount 1199 remote transmission diaphragm level transmitter works, the isolation diaphragm and filling liquid on the high and low pressure sides transmit the process pressure to the filling liquid, and then the filling liquid transfers the pressure to the sensing diaphragm in the sensor center. The sensing diaphragm is a tensioned elastic element whose displacement varies with the pressure (for GP gauge pressure transmitter, the atmospheric pressure is the same as that applied to the low-pressure side of the sensing diaphragm). Insulation transmitter, low-voltage side always maintain a reference pressure. The Zui displacement of the sensing diaphragm is 0.004 inches (0.1 mm), and the displacement is proportional to the pressure. The capacitive plates on both sides detect the position of the sensing diaphragm. The difference between the capacitance between the sensing diaphragm and the capacitor plate is converted to the corresponding current, voltage or digital HART (high-speed addressable remote transmitter data highway) output signal.

5. Rosemount 2088 Pressure Transmitter

Zui is a flexible and compact pressure transmitter used to measure the gauge pressure and absolute pressure from 1 to 4000 Psi.

6. Performance certification:

Rosemount took the lead in introducing Zui low-filling liquid transducer in the market, and equipped with Zui low-filling liquid diaphragm seal assembly, providing unparalleled overall system performance.

The difference between Rosemount:

In order to match the diaphragm seal system with the pressure transmitter in the range of 0 to 99%, the diaphragm seal requires a little more filling fluid behind the diaphragm than the transmitter. Otherwise, the sealing diaphragm will fail before reaching 99% full range. Rosemount filling transducer is suitable for use with diaphragm sealing system at least; Zui less filling transducer is compatible with less filling and high performance diaphragm sealing. Rosemount 1199 seals support less filling of Zui fluid, tailored for customers, and are designed to replace Rosemount transmitter in direct contact with process media. Rosemount 1199 features: Zui less filling flange, Zui less filling capillary fittings and very high performance diaphragm.

Rosemount 1199zui low-filling liquid-filled transmitter has a long-proven and unparalleled overall system performance.
