There are two new versions of the differential pressure gauge P2 display, a competitively priced 990M version with manual zeroing or a more technically advanced version, the 990A, with automatic zeroing.

These pressure gauges have a digital pressure display and dimensions of 143 x 96 x 48 mm, which ensures that they can be very easily fitted in a standard, DIN IEC 61554-compliant, control panel cut-out. The operating voltage is 24 VAC/VDC, however, using an optional mains power supply, they can also be operated from the mains.

The pressure gauges are suitable for monitoring air or non-aggressive gases. The three-wire output signal can optionally be set to 0...10 V or 4...20 mA with an ohmic resistance of 20...480 ohms. The maximum current consumption is less than 250 mA. Dependent on the version, the measuring range is between 0...25 Pa and 0...250 kPa, although the smallest measuring range is only available with automatic zeroing. The currently applied pressure can be displayed in three pressure units: Pascal, mbar or WC.  The response time of the output signal can be selected between 0.1 and 20 s. All available functions are selected and changed via the central rotary knob on the front panel.

In the 990M version, when the transducer is depressurized (at atmospheric pressure) the output signal in the parameter menu is manually zeroed using the rotary knob. In the 990A version the pressure transducer automatically carries out zeroing at regular short intervals. This means the drift behaviour is further reduced while control and maintenance effort are significantly reduced.
    
Alongside the analogue output signal, the differential pressure gauge is optionally provided with two adjustable relay switching outputs which can be switched AT up to 250 VAC/ 5A. The user can adjust these switching outputs within the measuring range so that connected devices can be activated when a defined pressure level is reached.

All electrical connections are located on the rear side of the gauge. Similarly, both of the pressure connectors for 4mm and 6mm tubes are located on the rear side.

As our quality management system has been certified in accordance with the international ISO 9001:2000 standard since 2002, we had to confront ourselves in July 2011 with the re-certification stipulated every 3 years. In the course of this re certification, the DEKRA ITS Certification Services subjected our entire quality related operating routines and processes to an extensive examination on site. In this regard, the auditors confirmed to us that our quality management system complies fully with the high requirements of the standard. On the basis of this positive audit result, the DEKRA ITS Certification Services once again issued to us the certificate, valid until 2014, for the areas of development, manufacture and distribution of pressure switches and pressure transducers.

In many cases, no reliable conclusion on the condition of a system can be drawn from an existing pressure, neither in building automation, air conditioning and clean-room technology, in valve control nor in fan and blower monitoring. For this purpose, a differential pressure transmitter is the preferred sensor, for it allows some statements on the differential pressure as well as on the over- and underpressure in a system.

However, present differential pressure transmitters show one disadvantage: The zero point always needs to be reset manually again and again in order to compensate the drift caused by ageing, temperature, or by system-related influences. The new sensors of the 984A and 985A series are now self-zeroing. Thus, the sensor can do without maintenance at regular intervals – an advantage that is not inconsiderable – as the removal of false ceilings or contamination caused by the maintenance technician will be avoided. Particularly for systems that require utmost hygienic or clean-room conditions or even high security in connection with access limitations, this is a decisive advantage in terms of operating costs.
The new differential pressure transmitter is available in two different designs, the 984A with a round (85 x 58 mm in diameter) or the 985A with a rectangular IP65 enclosure (81 x 83 x 60 mm). Both models use a small valve for zeroing or offset compensation done automatically at regular intervals. Their operating voltage is 24 VAC/VDC. Their three-wire output signal can be configured either for 0...10 V or for 4...20 mA (20...500 Ohm burden) with the aid of a jumper. The maximum current consumption of the LED display model is below 150 mA, while the one without display even draws less than 60 mA. These sensors are suitable for use in air or non-aggressive gases. They can be switched over between two different pressure ranges. Depending on the respective model, the measuring range is between 0...25 Pa and 0...250 kPa. By means of jumpers, one can also set the response time on site, for example, to suppress the display of short pressure surges. Also with the aid of a jumper, the user can choose between a linear or a square-rooted signal. The latter is useful for measuring volume flows. The round sensor enclosures meet the requirements of protection category IP 54, while the rectangular ones are even in conformity with IP 65.

On 10 June 2010, we were awarded to bear the status of an Authorized Economic Operator with the "Customs Simplifications/Security and Safety certificate (AEO F)”.
 
An Authorized Economic Operator (AEO) has a special status: He is considered to be particularly reliable and trustworthy, and this is why we are entitled to benefit from special customs clearance advantages.

The growing globalization and the changed situation in international security have induced the World Customs Organization (WCO) to create worldwide frame conditions for modern and effective risk management at the customs administrations by its "Framework of Standards to Secure and Facilitate Global Trade" (SAFE).

The introduction of the status of an Authorized Economic Operator is an essential element of this security initiative. At present, negotiations are being held with third countries (especially with the U. S., China and Switzerland) with the aim of worldwide recognition of this status.

The main objective is to ensure a continuous international supply chain, beginning at our pre-suppliers and going via Beck as a manufacturer down to our customers.

The status of an Authorized Economic Operator is valid in all Member States and not limited in time.

As of now, our 930.80 Climair® series differential pressure switches are available with a setting range from 20 to 300 Pascal. This extended range offers some advantages since the variety of applications of these differential switches will be even greater. Within the course of the year 2010, our present customers will, after previous consultation, get replacement for our earlier 930.80 model switches still having a setting range of 20-200 Pascal. New customers will, of course, be supplied with our new 20-300 Pascal generation.

This cable gland using a cap nut offers highly effective strain relief and a considerably better sealing function.

The installation of this gland has become easier since the integrated radial seal needs a lower torque, mainly less tightening forces, to ensure the sealing function as required by protection class IP 54.

This gland is designed for round cables with a diameter of 5 to 10 mm, while an optional reducer from 5 mm down to a diameter 3 mm is available for thinner cables. The nut has a width across flats of 20 mm, is made of polyamide and is provided with an NBR seal.

Series production will be available from 1 May 2009.

Not only do explosions often cause severe damage to property - not infrequently, they lead to personal injuries and invalidity. Obviously, as far as possible, such dangerous situations must be prevented in the first place. In some areas of industry, such as the chemicals sector, however, ignitable gas or air mixtures are frequently inevitable. Here, it is absolutely essential to avoid sources of ignition. Technical devices are one such potential source. If it is nevertheless impossible to dispense with them, they must be certified for so-called explosive zones. The ATEX product guideline 94/9/EG contains specifications for their construction (ignition-protection type) and quality management.
