Vaporizing Regulator Increases Accuracy and Reliability

Emerson has introduced the first vaporizing pressure reducing regulator for gas chromatograph analyzers with the option to separate the regulator body from the electronic enclosure, without compromising global hazardous location certifications. This design provides protection to the regulator’s electronics from extreme high temperatures in petrochemical refineries and processing plants.

The new TESCOM™ 44-6800 Series Vaporizing Regulator promotes greater reliability and accuracy in sample testing results, while simplifying system commissioning, reducing maintenance and enabling remote and local monitoring to meet global process requirements. The series works by ensuring the carefully controlled delivery of single-phase vapor samples of hydrocarbon mixtures to a gas chromatograph (GC) where the sample is separated and its physical properties analyzed.

Unlike traditional vaporizing regulators, the TESCOM 44-6800 Series optional certified separability enables the user to detach the electrical housing from the regulator body. This can then be installed in a lower temperature environment, preventing sensitive electronics from being exposed to ambient temperatures exceeding 149° F (65° C). 

The TESCOM 44-6800 is designed for a flow capacity of 0.02 and pressures up to 6000 psig. It is offered in both electric and steam versions. Emerson is launching the 44-6800 specifically for sample conditioning systems used in on-line gas chromatography analysis in oil and gas, petrochemical, and chemical applications.

The TESCOM 44-6800 features an industry standard 4-20 mA analog output to enable remote monitoring of the heater temperature and for data acquisition. Signals from the TESCOM 44-6800 can be output to modulating field devices, PLCs, and SCADA systems, among others, to achieve the networked goals of Industry 4.0 applications. The TESCOM 44-6800 Series also has the option for an LED screen for local monitoring in the field.
