1.1 Function and configuration

Pressure transmitters D86 and D87 are instruments for hydrostatic level measurement.

Pressure transmitter D86

Measuring cell: dry, ceramic-capacitive Diaphragm: flush, sapphire-ceramic Series: suspension version Standard application: Level and gauge measurements in water/sewage water, flumes, basins, deep wells, vessels and tanks

Pressure transmitter D87

Measuring cell: dry, metallic-capacitive Diaphragm: Duratherm 600 Series: suspension version Standard application: Level and gauge measurements in water/sewage water, flumes, basins, deep wells, vessels and tanks

Product description

Output signal

The output signal is transferred as a digital or analogue signal from the pressure transmitter to the signal conditioning instrument:

• analogue output signal

- unstandardised (in conjunction with VEGA signal conditioning instrument)

- 4 … 20 mA standardised

• digital output signal (VBUS) for connection to a digital VEGA signal conditioning instrument (VEGAMET 514V, 515V or VEGALOG

571)

The pressure effects a capacitance change on the measuring cell. This capacitance change is detected by an ASIC (Application Specific Integrated Circuit) and converted into a pressure-proportional signal by the integrated electronic module with microcontroller. Precise, high-resolution digital processing of measurement data ensures excellent technical data.

To improve reliability, the functionality of important electronic components is continuously checked, and internal parameters such as sensor value, temperature and operating voltage are closely monitored.

2 Mounting

Mounting

2.1 Mounting instructions

The pressure transmitter can be mounted in any position. Cable entries must point downwards to avoid moisture ingress. For this purpose, the housing can be rotated by 330° in relation to the mounting part.

2.2 Compensation of the atmospheric pressure

On instruments for gauge pressure measurement, the atmospheric pressure is compensated via a breather facility integrated in the housing.

Pressure transmitter with direct cable outlet

- via the capillaries of a special cable con-

nected to the terminals, protection IP 68

We recommend leading the special cable into the external connection housing VEGABOX 01 (accessory) and carrying out the pressure compensation via the integrated breather facility there.

External connection housing

Observe the following instructions:

- as a rule, there must be the same atmos-

pheric pressure on the breather facility as on the vessel

- the pressure compensation must be done

in a dry environment

- with vertical wall mounting, cable entries

must point downward to avoid moisture ingress and buildup on the breather facility.

An appropriate connection seal must be used for mounting. This seal is either supplied with the pressure transmitter or must be provided by the customer.

Electrical connection

3 Electrical connection

3.1 Connection instructions

The electronics in the pressure transmitter requires a supply voltage of 12 … 32 V DC. It is designed in two-wire technology, i.e. the supply voltage and the digital output signal are led via the same two-wire cable to the terminals.

This external energy is provided via a separate power supply unit, e.g.:

- power supply unit VEGASTAB 690

- processing unit with integrated DC voltage source (e.g. active PLC input)

- VEGAMET, VEGALOG or VEGADIS 371

Make sure that the external energy source is reliably separated from the mains circuits acc. to DIN VDE 0106, part 101. The abovementioned VEGA devices meet this requirement and protection class III is therefore guaranteed.

The external energy source must provide a terminal voltage of at least 12 V on the transmitter. The actual terminal voltage on the transmitter depends on the following factors:

- output voltage UH of the external energy source under nominal load.

- electrical resistance of the connected instruments in the circuit (see connected instruments, load resistance).

Note the following instructions for electrical connection:

- Connection must be made according to the country-specific installation standards (e.g. in Germany acc. to the VDE regulations).

- The terminal voltage must not exceed 36 V, to avoid damage to the electronics.

- The electrical connection must have a protective measure against polarity reversal.

- Connection of Ex sensors only by qualified personnel.

- The wiring between pressure transmitter and power supply can be made with standard two-wire cable.

- If strong electromagnetic interference is expected, screened cable is recommended. The screening must be done on both ends. Note the installation regulations for use in Ex areas.

- In case of overvoltages, we recommend the use of pressure transmitters with integrated overvoltage protection or the installation of VEGA overvoltage arresters.

- In the cable entry, a seal correctly fitting the cable should be used.

Safety information for Ex applications

As a rule, do all connecting work in the complete absence of line voltage. Always switch off the power supply before you carry out connecting work on the sensors. Protect yourself and the instruments.

Qualified personnel

Instruments used in Ex areas must be installed only by qualified personnel. The qualified personnel must observe and understand the mounting regulations and the supplied type approval certificates and conformity certificates.

If an instrument is used in hazardous areas, the respective regulations, conformity certificates and type approvals of the sensors, separators or safety barriers must be noted (e.g. DIN VDE 0165).

Pressure transmitters D86/D87 17

Electrical connection

Sensors used in Ex areas must be connected only to intrinsically safe circuits. The permissible electrical values are stated in the conformity certificate or the type approval certificate.

Intrinsically safe circuits with more than one active instrument (instrument delivering electrical energy) are not allowed. Please note the special installation regulations (DIN VDE

0165).

Certain pressure transmitters are provided with a warning label informing of measures to be taken to avoid the danger of electrostatic discharge. Note the content of the warning label.

4.1 Adjustment structure

The hydrostatic pressure transmitters come with or without adjustment capability.

After connection to the supply voltage, the electronics carries out a self-test (approx. 2 sec.) and the current in this signal circuit (sensors with analogue output signal) takes on a value of > 21.6 mA.

Sensors with adjustment (electronics version A and C)

Sensors with electronics version A deliver a pressure-proportional current as measured value and are not adjustable. All settings such as adjustment, density correction etc. are carried out via the signal conditioning instrument. The sensors with electronics version C come preadjusted according to the measuring range of the sensor (factory setting). In unpressurised condition, they consume a current of 4 mA. With a pressure at the measuring range final value, they consume a current of 20 mA.

Sensors with adjustment insert in the sensor (electronics version K)

The adjustment insert with selection switch allows:

- zero adjustment "z" = empty adjustment

- span adjustment "s" = full adjustment

- adjustment of an integration time (time) "ti"

Adjustment in external connection housing VEGADIS 12 (electronics version L)

The adjustment insert with selection switch (VEGADIS 12 with display) allows:

- zero adjustment

- span adjustment

- adjustment of an integration time (time)

- adjustment of a value for zero point (empty)

- adjustment of a value for span (full)

- adjustment of the decimal point for the displayed value

Adjustment with HART® handheld (electronics version I, K and L)

The hydrostatic pressure transmitters with electronics version I, K and L can be adjusted with the HART® handheld like other HART® capable instruments. A manufacturer specific DD (Device Description) is not necessary. The sensors work with the HART standard menus.

Adjustment of VEGA signal conditioning instrument VEGAMET (electronics version A and B)

Electronics version A delivers a non-standardised output signal to a VEGAMET with analogue input.

Electronics version B transfers the measured value digitally (VBUS) to a digital VEGAMET (514V, 515V, 614V).

The signal conditioning instrument itself, as well as the pressure transmitter, can be operated by means of the standard six-key adjustment field (with clear dialogue text display) on the signal conditioning instrument.

Adjustment with PC and adjustment program VVO (electronics version B, I, K and L)

With the adjustment program VVO (VEGA Visual Operating) on the PC you can conveniently adjust the pressure transmitters with electronics version B, I, K and L. The PC communicates with the sensor through the interface converter VEGACONNECT 2 or the standard RS 232 interface cable. A digital adjustment signal is superimposed on the signal and supply cable. The adjustment can be carried out from any location on the signal cable, on the sensor directly, on the signal conditioning instrument or on the VEGALOG processing system.

4.2 Sensor without adjustment

Sensors with electronics version C have no adjustment capability and come preset to the stated measuring range.

• By pushing the "+" and "–" keys simultane-

ously, the current jumps directly to 4 mA or you can adjust a current of 4 mA with the "+" and "–" keys.

Note:

- A modification of zero does not influence the span, i.e. the measuring range final value is simply shifted.

- It is also possible to adjust currents for partial fillings or partial pressures, e.g. 8 mA for 25 % and 16 mA for 75 %.The pressure transmitter then automatically calculates the values for 0 % or 100 % (only possible with a level difference >3.3 %).

Integration time

An integration time ti of 0 … 10 s can be adjusted to damp pressure shocks.

Procedure

• Set rotary switch to ti.

• By pushing the "-" 10 times, make sure that

the integration time is set to 0 s.

• For each 1 s desired integration time, the "+" key has to be pushed once.

Adjustment range of zero:

-20 % … +95 % of nominal measuring range (corresponds to a turn up of up to +95 %)

2 Adjustment of span

(e.g. level at maximum)

• Set rotary switch to span.

• By pushing the "+" and "–" keys simultane-

ously, the current jumps directly to 20 mA or you can adjust a current of 20 mA with the "+" and "–" keys.

Adjustment range of span:

3.3 % … 120 % of nominal measuring range (corresponds to a turn down 1 : 30)

Setup

4.4 Setup with HART® handheld

Sensors with electronics versions I, K and L can be set up with the HART® handheld. A special DD (Data Device Description) is not necessary. Just connect the HART® handheld to the sensor signal cable after you have connected the sensor to supply voltage.

250

Note:

If the resistance of the voltage supply is less than 250 W, a resistor must be looped into the signal/connection cable during adjustment. The digital adjustment and communication signals would otherwise be short-circuited through insufficient resistance of e.g. the supply voltage source or the processing system. In such case, communication with the sensor would not be ensured. Simply connect the adjustment resistor in parallel to the connection socket of the HART

handheld.

Diagnostics

Maintenance

The pressure transmitters D86/D87 are maintenance free.

Should dismounting of the pressure transmitter (e.g. for vessel cleaning) be necessary, we recommend the use of new seals. Use only original seals from VEGA.

Remedying faults

Through continuous self-monitoring, series 80 pressure transmitters offer maximum reliability. However, if faults occur, please check the following before removing the pressure transmitter:

- the atmospheric pressure compensation (only with gauge pressure measuring ranges),

- the electrical connections.

Checking atmospheric pressure compensation

First of all, open the cover of the housing in which the atmospheric breather facility 1) is located. The displayed measured value must not change. If, however, the displayed value changes, the compensation of the atmospheric pressure does not function correctly and the measured value will be distorted. Therefore check:

- the breather facility on the housing

- the external connection housing VEGADIS 12

- the capillaries in the special housing.

Note:

The same atmospheric pressure must be acting on the breather facility and the open vessel.

Checking electrical connections

Pressure transmitter terminals

1 2 3

Current

Voltage

Current

External energy source

Checking the voltage

- The terminal voltage on the pressure transmitter must be at least 12 V DC.

- The terminal voltage on VEGADIS 12 must be at least 12 V DC or 17 V DC (with display).

- The supply voltage for the pressure transmitter through a VEGAMET signal conditioning instrument must be approx. 18 V DC (on VBUS 25 V DC).

Checking the current

These values are only valid for pressure transmitters with analogue signal transmission, not for pressure transmitters with digital output signal (VBUS).

• Initial current with uncovered diaphragm of the pressure transmitter: approx. 4 mA (5 mA when operated on a VEGA signal conditioning instrument)

• Measuring current during operation: 4 … 20 mA (5 … 19 mA when operated on a VEGA signal conditioning instrument)

• Exceeding or falling short of the specified measuring range: 20.5 mA or 3.8 mA

• Pressure transmitter defective or shortcircuit: current 22 mA or 3.6 mA
