With the PB series, Baumer is introducing a new pressure transmitter family based on a modular system which can be adjusted individually to customers’ needs. Remarkable is the high accuracy (of up to 0.1 % F.S.) over a large compensated temperature range of -40 °C up to +85 °C. The pressure range is between 100 mbar and 1600 bar. The FlexProgrammer 9701 enables the transmitter’s easy configuration.

With the Barflex, Baumer offers a robust digital manometer with integrated data memory. In the ATEX version Barflex 4Y, it is also suitable for the use in rough and hazardous surroundings. It can measure the gauge and absolute pressure of almost all liquid and gaseous media in a range from 500 mbar to up to 1000 bar and with an accuracy of up to 0.1 % of full scale. Used as a barometer, the Barflex displays the atmospheric pressure from 200 to 1150 hPa with an accuracy of 1 hPa.

Variohm EuroSensor has launched a new range of potentiometric linear position sensors for precision measurement from 10 mm to 300 mm that are supplied in open housings - reducing component cost for high accuracy position feedback applications. The PTP series from Novotechnik is a robust two-part design including a multi-fingered wiper assembly and separate open sided extruded aluminium housing containing a conductive plastic track.

For applications in gaseous and dusty surroundings, Baumer offers its FlexLevel Switch 4401 in various ATEX versions. They enable a safe level detection in hazardous areas. The ATEX certifications cover the zones 0, 1 and 2 as well as the zones 20, 21 and 22. The FlexLevel Switch can be easily configured on PC via the FlexProgrammer 9701. When used with a cooling neck, the switch is suitable for process temperatures from -40°C to up to 200 °C.

The new, intrinsically safe Temposonics IS position sensors by MTS assure a safe working environment where ignitable mixtures of materials occur. Developed for the linear position or level measurement in hazardous areas they meet all the requirements of equipment group category II. Along with the corresponding certified safety barriers they can be used directly in hazardous areas of instrument category 1/2G and 2D and in order to that can even be mounted to zone 0.

Gems Sensors and controls has announced the launch of a new range of magnetically actuated proximity switches for a wide range of customer applications. Versatile, low cost and compact, these new switches are hermetically sealed for long lasting performance and easy installation.

For its FlexLevel Switch 4401, Baumer offers a sliding connection making the hygienic level switch suitable for high process temperatures of up to 200 °C. The optional sliding connection is available in 100 and 250 mm length and can serve as a cooling neck or extension, for example if the medium has to be reached through the tank insulation or the level detection has to be adjusted to a certain height. Thanks to the DN38 process connection, the sensor is excellently suitable for food and beverage industry applications. For the use in hazardous areas, different ATEX versions are available.

Calex is delighted to announce an innovative new range of compact infra-red pyrometers with built-in digital communications for easy systems integration.

When it comes into force at the end of December 2009 the new Machinery Directive will reference the new EN 13849 standard for safety-related parts of the control system instead of the familiar EN 954-1. ifm electronic Ltd is ahead of the game with a range of fail-safe inductive sensors fully compliant with the latest standards.

Ever since it was launched, Gefran’s series of rod-type magnetostrictive transducers for inside cylinder applications was a great success, confirming the product’s quality and its satisfaction of market demands.
