Radar unit handles expanded oil field duties
An expanded Rosemount 3300 Series guided wave radar level and interface transmitter is designed to help users enhance safety and efficiency in extreme environments.
The expansion includes special probes designed to prevent leakage and perform reliably when exposed to high temperature and pressure conditions over extended periods. The 3300 is now available for temperatures as high as 750° F. and pressures as high as 5,000 psig. Common applications with these extreme environments include refinery distillation columns, liquefied gases and freons, power plant utility heater vessels, gas-oil production separators, oil water separators, and compressor tanks.
Materials for the special Rosemount 3300 probes have been selected to avoid stress fractures commonly induced by high pressures and temperatures. The design of the new probes adapts to thermal expansion and contraction, retains strength, and provides efficient feed-through of microwave signals, the company points out.

New temperature calibrators
New JOFRA advanced temperature calibrators (ATC) series combines the accuracy of laboratory temperature sources with the speed and portability of field dry-block calibrators. Units help make it possible to calibrate even more sensors at the same time along with large and odd size sensors in either a large diameter dry block or in a liquid bath.
Calibrators are available in six temperature ranges. All six of the ATC series calibrators feature the dual-zone heating block designed for optimum performance and superior temperature homogeneity throughout the block.

New push-fit tube fitting
The new Phastite tube fitting is assembled via simple push-fit operation, and it provides permanent connections for fluid systems operating at as much as 20,000 psi.
The firm says its fitting can replace cone and thread or welded fittings. Phastite employs a compression assembly principle using a novel form of toothed profile, which makes the seal. The fittings are supplied as one-piece components.
