Application area

Measured products

3.2 Principle of operation

VEGABAR 38 is suitable for applications in virtually all industries. It is used for the measurement of the following pressure types.

• Gauge pressure

Absolute pressure

• Vacuum

Measured products are gases, vapours and liquids.

Depending on the process fitting and measurement setup, measured products can be also viscous or contain abrasive substances.

Measured variables The VEGABAR 38 is suitable for the measurement of the following process variables:

• Process pressure



• Level

Fig. 3: Process pressure measurement VEGABAR 38

Measuring system pressure

The sensor element is the Mini-CERTEC ® measuring cell with robust ceramic diaphragm. The process pressure deflects the ceramic diaphragm and causes a capacitance change in the measuring cell.

This capacitance change is converted into an electrical signal and outputted as measured value via the output signal.

Relative pressure : the measuring cell is open to the atmosphere.

The ambient pressure is detected in the measuring cell and compensated. It thus has no influence on the measured value.

Absolute pressure : the measuring cell contains vacuum and is encapsulated. The ambient pressure is not compensated and does hence influence the measured value.

The recessed installation is particularly suitable for applications with gases, vapours and clear liquids. The measuring cell seals are positioned laterally as well as in front.

4.1 General instructions

The instrument is suitable for standard and extended ambient conditions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1. It can be used indoors as well as outdoors.

Note:

For safety reasons, the instrument must only be operated within the permissible process conditions. You can find detailed information on the process conditions in chapter " Technical data " of the operating instructions or on the type label.

Hence make sure before mounting that all parts of the instrument exposed to the process are suitable for the existing process conditions.

These are mainly:

• Active measuring component

Process fitting

Process seal

Process conditions in particular are:

• Process pressure

Process temperature

Chemical properties of the medium

• Abrasion and mechanical influences

The permissible process pressure range is specified by "MWP" (Maxi mum Working Pressure) on the type label, see chapter " Structure ".

The MWP takes the element of the measuring cell and processing fitting combination with the weakest pressure into consideration and may applied permanently. The specification refers to a reference temperature of +20 °C (+68 °F). It also applies when a measuring cell with a higher measuring range than the permissible pressure range of the process fitting is installed order-related.

In addition, a temperature derating of the process fitting, e. g. with flanges, can limit the permissible process pressure range according to the respective standard.

Note:

In order to prevent damage to the device, a test pressure may only exceed the specified MWP briefly by 1.5 times at reference tempera ture. The pressure stage of the process fitting as well as the overload resistance of the measuring cell are taken into consideration here

(see chapter " Technical Data ").

Protection against moisture

Protect your instrument against moisture ingress through the following measures:

• Use a suitable connection cable (see chapter " power supply ")

Connecting to

• Tighten the cable gland or plug connector


Ventilation and pressure compensation

4 Mounting

• When mounting horizontally, rotate the housing so that the cable gland or plug connector point downward

• Lead the connection cable downward in front of the cable entry or plug connector

This applies mainly to outdoor installations, in areas where high humidity is expected (e.g. through cleaning processes) and on cooled or heated vessels.

Make sure that the degree of contamination specified in chapter "

Technical data " meets the existing ambient conditions.

Ventilation and pressure compensation for VEGABAR 38 are provided by an air-permeable, moisture-blocking filter element.

Note:

In case of horizontal mounting, turn the housing so that the filter ele ment points downward after the instrument is installed. This provides better protection against buildup.

Screwing in

Fig. 9: Position of the filter element

1 Filter element

For effective ventilation, the filter element must always be free of buildup.

Devices with threaded fitting are screwed into the process fitting with a suitable wrench via the hexagon.

See chapter " Dimensions " for wrench size.

Warning:

The housing or the electrical connection may not be used for screwing in! Depending on the device version, tightening can cause damage, e. g. to the rotation mechanism of the housing.

Permissible process pressure (MWP) - Mounting accessory

Temperature limits

The permissible process pressure range is stated on the type label.

The instrument should only be operated with these pressures if the mounting accessory used also fulfils these values. This should be en sured by suitable flanges, welded sockets, tension rings with Clamp connections, sealings, etc.

Higher process temperatures often mean also higher ambient temperatures. Make sure that the upper temperature limits stated in chapter " Technical data " for the environment of the electronics housing and connection cable are not exceeded.

6 Access protection

6.1 Bluetooth radio interface

Devices with a Bluetooth radio interface are protected against unwanted access from outside. This means that only authorized persons can receive measured and status values and change device settings via this interface.

A Bluetooth access code is required to establish Bluetooth communication via the adjustment tool (smartphone/tablet/notebook).

This code must be entered once when Bluetooth communication is established for the first time in the adjustment tool. It is then stored in the adjustment tool and does not have to be entered again.

The Bluetooth access code is individual for each device. It is printed on the device housing with Bluetooth. In addition, it is supplied with the device in the information sheet " PINs and Codes " In addition, the

Bluetooth access code can be read out via the display and adjustment unit, depending on the device version.

The Bluetooth access code can be changed by the user after the first connection is established. If the Bluetooth access code is entered incorrectly, the new entry is only possible after a waiting period has elapsed. The waiting time increases with each further incorrect entry.

The emergency Bluetooth access code enables Bluetooth communication to be established in the event that the Bluetooth access code is no longer known. It can't be changed. The emergency Bluetooth access code can be found in information sheet " Access protection ".

If this document is lost, the emergency Bluetooth access code can be retrieved from your personal contact person after legitimation.

The storage and transmission of Bluetooth access codes is always encrypted (SHA 256 algorithm).

6.2 Protection of the parameterization

The settings (parameters) of the device can be protected against unwanted changes. The parameter protection is deactivated on delivery, all settings can be made.

To protect the parameterization, the device can be locked by the user with the aid of a freely selectable device code. The settings (parameters) can then only be read out, but not changed. The device code is also stored in the adjustment tool. However, unlike the Bluetooth access code, it must be re-entered for each unlock. When using the adjustment app or DTM, the stored device code is then suggested to the user for unlocking.

The emergency device code allows unlocking the device in case the device code is no longer known. It can't be changed. The emergency device code can also be found on the supplied information sheet " Access protection ". If this document is lost, the emergency device code can be retrieved from your personal contact person after legitimation.


6 Access protection

The storage and transmission of the device codes is always encrypted (SHA 256 algorithm).

6.3 Storing the codes in myVEGA

If the user has a " myVEGA " account, then the Bluetooth access code as well as the device code are additionally stored in his account under

" PINs and Codes ". This greatly simplifies the use of additional adjust ment tools, as all Bluetooth access and device codes are automatically synchronized when connected to the " myVEGA " account

11.1 Maintenance

If the device is used properly, no special maintenance is required in normal operation.

In some applications, product buildup on the diaphragm can influence the measuring result. Depending on the sensor and application, take precautions to ensure that heavy buildup, and especially a hardening thereof, is avoided.

The cleaning helps that the type label and markings on the instrument are visible.

Take note of the following:

• Use only cleaning agents which do not corrode the housings, type

• label and seals

Use only cleaning methods corresponding to the housing protection rating

11.2 Rectify faults

The operator of the system is responsible for taking suitable measures to rectify faults.

The device offers maximum reliability. Nevertheless, faults can occur during operation. These may be caused by the following, e.g.:

The first measures are:

• Evaluation of fault messages

Checking the output signal

Treatment of measurement errors

A smartphone/tablet with the adjustment app or a PC/notebook with the software PACTware and the suitable DTM offer you further com prehensive diagnostic possibilities. In many cases, the causes can be determined in this way and the faults eliminated.

Depending on the reason for the fault and the measures taken, the steps described in chapter " Setup " must be carried out again or must be checked for plausibility and completeness.

Should these measures not be successful, please call in urgent cases the VEGA service hotline under the phone no. +49 1805 858550 .
