Orders for the new MINICOMB compact pressure switch 30x30 / ATEX can be placed from now – deliveries start from ab 21. March 2016.

For further questions please contact our sales team.

By customer request PINTER should develop a powerful and precise yet small electronic pressure switch.

Requirements
The electronic pressure switch is to be used to monitor supply air pressure for different systems, wheras following criteria needed particular attention:

1) high vibration resistance (7G contstant load)
2) high breaking capacity (7A PNP - output)
3) compact dimensions
4) economical

Realization
The pressure switch is primarily used on engines and machines with more than 1000 KW. High vibrations up to a frequency range of about 300 Hz with a constant load of 7G are usually encountered.
The special design of the switch allows for use in this environment without an assembly with vibration isolation.

This is achieved by a special construction of the enclosure of the pressure switch, e.g. bolted connections have been largely omitted.

The output is a special PNP-transistor for switching loads up to 7 A. In addition, the output can handle a peak current of up to 14 A.
These characteristics are necessary because during a switching operation different other consumers will be activated and for a period of up to 10s peak currents occur, that flow through the transistor.

Regarding the little installation space near engines and machines, high ambient temperature of up to 80°C as well as high heat generation during switching with high currents, the challange was to keep thermal load within reasonable limits without additional cooling elements.

Cost of development and construction of the pressure switch has been reduced to a minimum despite the high technical requirements.

Basis for cost-effective development were the long-time know-how in Pressure Measurement, the existing product base as well as the extensive network of partners, in particular in the field of electronics development.

In order to take into account different environmental conditions, the pressure switch has also been optimized to prevent damage from seawater, so for example enclosure parts are made of seawater resistant aluminum.

By customer request, the switch does not have a display or any operation keys. Instead it is delivered completely factory-set in order to rule out any manipulation.
The switching states are visualized by two LEDs (red and green). The switching points are within the low mbar range, which requires a high accuracy and repeatability of the switch.

PINTER developed this switch in only 4 weeks !
Serial delivery started already 2 weeks after initial sample release by the customer.

PINTER extends range of electronic pressure switch with high-pressure variants.

Obrigheim, October 2014

The innovative new electronic pressure switches series MINICOMB-EDS, which was introduced by PINTER in May 2014 is now to be supplemented with further variants.

In addition to other material versions of the wetted parts in stainless steel 1.4301 (AISI 304) or 1.4404 (AISI 316L), the pressure ranges will be expanded to 600 bar.

The new versions are especially suitable for hydraulics applications.

The new MINICOMB-EDS versions are available for order immediately - orders will be shipped from January 2015.

PINTER introduces new electronic pressure switch

Obrigheim , May 2014.

With the MINICOMB-EDS PINTER introduces a new and innovative electronic pressure switch for fluid technology in mechanical engineering.

The pressure switch is characterized by its robust design, high functionality and user friendliness.
With the ergonomic 3-button control panel, the pressure switch is operated with a menu according to VDMA standard. In addition to the standard menu the MINICOMB-EDS features a multilingual plain text menu which clearly explains the selected menu item. Thus, a rapid and hassle-free installation is ensured.

Review of set parameters is easy and summarized for each output in the status menu - even when password protection is active.

The various menus, parameters and settings are displayed on the monochrome high-resolution full graphic OLED display. The 180° rotatable display allows for excellent readability even under direct sunlight or large angles.

The new MINICOMB-EDS is available from 01. Juli 2014.

When natural gas is being extracted from gas fields only, the borehole is build up as a so called gas-probe. This gas-probe is hard-piped and flange mounted onto a valve manifold.
The valve manifold itself is the borehole completion – it consists of two main slide valves, of which one is made out as an automatic safety slide valve.
In case of critical process pressure the safety slide valve securely closes the gas-probe - thus in normal operation the applied natural gas can be extracted safely from the borehole and fed in a pipeline.
As most of the boreholes are somewhere on the free field and have no electrical supply, pneumatically powered components are used since compressed air can be stored in pressure tanks easily.

The control is set up with two pneumatic safety pressure limiters, whereof one monitors the minimal and the other the maximal natural gas pressure.
Also a pressure gauge is mounted for visualizing the actually applied natural gas pressure.
In general these three measuring instruments are flange mounted onto the process piping.
Furthermore a hand valve for manual operation. It is mounted in the control-air line and hard-piped with the two pressure limiters.

An expensive and work-intensive design!

PINTER has integrated all these and more features into a single safety control and measuring device:

For example, an additional pressure switch to monitor the control air has been integrated.
In case of pressure drops or failures a battery-powered intrinsically safe (Ex i) minimum-alarm is triggered.
The actual control air pressure is also clearly readable from the integrated pressure gauge.
Obviously the control air monitor is designed to close the safety slide valve in case of an error.

Minimal and maximal switch points are freely adjustable from 0 to 160 bar. This wide adjustment range guarantees a stable natural gas supply. As with the control air, the actually applied natural gas pressure is indicated.

Also an emergeny-shut-off function was integrated in this measuring and control device.

Basis for both, the process monitoring and the control air monitoring is the well proven and wear-free MANOCOMB precision pressure switch series

The process connection of the whole unit is made out as a flange-type diaphragm seal and protects the integrated measuring instruments from damages through solid material which might be carried along with the natural gas as well as from dynamic pressure boosts.
The diaphragm itself is mechanically protected from deposits and abrasive rock particles by a special coating.

An elaborately designed installation is turned obsolete with this combined measuring and control unit!
