Process pressure: Level and pressure measurements

Measuring principle

The pressure measuring cell converting the pressure into a signal which can be evaluated electrically is the heart of the pressure transmitter. This pressure-dependent signal is converted by the integrated electronics into a standardized output signal. Different sensors are used to detect the pressure. The ceramic cell characterizes by an excellent long-term stability and high overload resistance. The metal cell covers even higher measuring ranges and use stainless steel as diaphragm material.

For all areas of industry

VEGABAR series 60

VEGABAR series 60 meets all the requirements placed on suspension pressure transmitters. Excellent measuring precision, overload resistance, temperature stability and corrosion resistance are the essential criteria that it satisfies. In conjunction with application-optimized housing versions and electronics, these suspension pressure transmitters are ideal for use in rough environments.
Especially the front-flush, abrasion resistant CERTEC® with its double seal system offers high reliability and operational safety.

For gauge measurements


These suspension pressure transmitters are designed for gauge measurement in water/waster applications. Different housing materials in combination with different cable materials offer all necessary options.

Plate heat exchanger

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. This has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids spread out over the plates. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. Plate heat exchangers are now common and very small brazed versions are used in the hot-water sections of millions of combination boilers. The high heat transfer efficiency for such a small physical size has increased the domestic hot water (DHW) flowrate of combination boilers. The small plate heat exchanger has made a great impact in domestic heating and hot-water. Larger commercial versions use gaskets between the plates, smaller version tend to be brazed.

The concept behind a heat exchanger is the use of pipes or other containment vessels to heat or cool one fluid by transferring heat between it and another fluid. In most cases, the exchanger consists of a coiled pipe containing one fluid that passes through a chamber containing another fluid. The walls of the pipe are usually made of metal, or another substance with a high thermal conductivity, to facilitate the interchange, whereas the outer casing of the larger chamber is made of a plastic or coated with thermal insulation, to discourage heat from escaping from the exchanger.
