2.2 Function

The device is suitable for applications in virtually all industries for lling and water level measurement, especially for fresh

water, wastewater and salt water. The slim construction design allows the use especially at conned space conditions, e.g. at

bore holes and wells with small diameter.

The high precise, long term stable and robust ceramic measuring cell, the stainless steel enclosure and the thick-walled,

length stable extension cable with highly stressable steel core ensures reliable precise measuring values and allows the

operation also at demanding environmental conditions, e.g. low temperatures, high shock and vibration loads or at

problematic liquids.

The hydrostatic liquid pressure acts directly (dry system) via the process diaphragm to the capacitor at the back side. The

pressure causes there a capacitance change which is converted into a corresponding output signal.

For optional measuring the temperature, an integrated long-term stable platinum temperature sensor is used. The measured

temperature value can be read out at the version 09-V (RS485 Modbus-RTU) by the digital interface or the resistance signal

can be evaluated at the version 09-A (current 4…20mA FSK) in parallel to the pressure conditioned analogue current signal

per 3-wire-technology.

The parameterization and operation can be made by the integrated wired interface.

2.3 Conguration

The device consists on the components:

① Measuring cell ③ Extension cable

② Electronic enclosure ④ Ventilation/pressure compensation

2.4 Product label

The type label contains the most important data for identication and use of the instrument.

① Type code ④ Assignment

② Serial number ⑤ Safety notes

③ Technical data ⑥ Approvals

2.5 Packaging, transport, storage

The device is protected by packaging. It can handle normal loads during transport. Transport must be carried out in due

consideration of the notes on the transport packaging.

Nonobservance of these instructions can cause damage to the device.

The delivery must be checked for completeness and possible transit damage immediately at receipt. Ascertained transit

damage or concealed defects must be appropriately dealt with.

3 Installation

3.1 Ambient and process conditions

The correct function of the device within the specic technical data can only be guaranteed, if the permitted ambient and

process conditions at the installation place (see chapter Technical Data) will not be exceeded. Hence make sure before

mounting that all parts of the instrument exposed to the process (e.g. measuring membrane, process seal, enclosure,

extension cable) are suitable for the existing process conditions (e.g. process pressure, process temperature, chemical

properties of the medium, abrasion, mechanical inuences).

3.2 Installation place

The device should be installed at a point free from ow and turbulence, or a guide tube should be used. The internal

diameter of the guide tube should be at least 1 mm bigger than the outer diameter of the device.

Install device below the lowest measuring point.

Do not mount the device in the ll ow, in the suction area of a pump, in the tank outlet or at a point in the container which

could be affected by pressure pulses from an agitator.

The installation of the device should be made if possible at temperature calmed places. High process temperature steps can

produce short-time higher measuring signal deviations.

At underrun of the dew point, e.g. cold process medium at high environmental temperature, there is the possibility of

condensate formation within the pressure measuring sensor, which can lead to temporary increased measurement deviations

resp. malfunctions. These deviations are fully reversible by drying the condensate.

The cable must end in a dry room or a suitable terminal box.

① Filling level sensor ④ Mounting clamp – see accessories

② Guide pipe ⑤ Mounting screw – see accessories

③ Extension cable (bending radius > 80mm) ⑥ Field enclosure

3.3 Installation notes

Do not remove packaging until just before mounting and check the device for any damage. The transport protection cap,

which is attached at the process connection resp. the diaphragm, must only be removed immediately before the installation.

The transport protection cap must be removed. The diaphragm may not be damaged.

Pollution or damaging of the pressure compensation capillary can lead to faulty measuring results.

If the cable is shortened, the lter at the pressure compensation tube has to be reattached.

WARNING: Install the device only when the system is pressureless. There is a risk of fast escaping media resp. pressure blow.

WARNING: Let the system cool down sufciently before installing the device. There is a risk of dangerous and hot media

escaping.

4 Electrical connection

WARNING: Install the device only in de-energized state.

NOTE: For start-up deactivate all connected control devices, to avoid unwanted control reactions.

The device must be grounded, preferred by the metallic process connection, alternatively by the cable shield.

The optional eld enclosure can be connected to earth by the connection screw PE/PA at the side of the enclosure.

Install cable separated from power leading cables, if existing connect shield to earth.

4.1 Electronic output 09-A – 4…20mA, FSK interface

The digital communication protocol uses Frequency Shift Keying (FSK) technology and is superimposing onto the analogue

sensor signal 4…20mA. This allows a two-way-communication and thus allows the transmission of additional information’s,

that going above the normal process variables, from or to an intelligent eld device.

The communication protocol communicates with 1.200 Bit/s without interrupting the 4…20mA signal an thus allows the host

application (master), to receive two or more digital actualizations per seconds from an intelligent eld device. The digital

signal does not disturb the 4…20mA.

The communication protocol offers two simultaneous communication channels: the analogue 4…20mA signal and a digital

signal. The 4…20mA signal transmits the primary measuring value by the 4…20mA current loop, the fastest and most reliable

industry standard. The digital signal transmits additional information’s from the device like device state, diagnosis date,

additional measuring values or calculated values, etc.

The combination of both principles in one installation allows a cost effective and especially robust comprehensive eld

communication solution, which can be simply uses and congured.

Use a cable 2-core, twisted, shielded.

Observe maximum permitted supply voltage Us at the terminals L+/L-:

• Us = 9…35VDC

Observe maximum permitted load resistor RL of the analogue output:

• RL ≤ (Us - 9V) / 22mA

Connection current 4…20mA FSK / Pt100 – 3-wire

Consider resistor 240Ω within wire +L for connection of the FSK-communication device.

3.4 Field enclosure

For connection of hydrostatic lling level sensors with reference air compensation an air pressure compensation element

is installed at the side of the eld enclosure. This may not be damaged or polluted, otherwise this can lead to wrong

measurements of the lling level sensor and to the resulting dangers.

After installing the device check if all cable glands as well as the enclosure cover are tightly screwed.

4.2 Electronic output 09-V – Interface RS485 Modbus-RTU

The Modbus protocol is a communication protocol, that base on a master/slave architecture.

All devices are connected by two data wires (A+ / B-) and by one COMMON-wire (C/L-).

An original RS485 allows the connection of 32 slaves within one segment. The device has a load of only 1/8 of the standard

load (Rin ≥ 96 kΩ), thus up to 256 of the devices can be theoretically operated within one network segment. However the

number is limited to 247 due to the Modbus address space.

The both termination resistors RT prevent reections on the data wires. The optimum resistor value depends on the wave

impedance of the used cable, but a value of 120 Ohm is a popular choice.

The polarisation network is necessary, to ensure suitable potentials, if none of the devices transmits and thus the wires

A+ and B- are undened (high impedance). The value for RP depends e.g. on bus load or the termination resistors.

Recommended values are between 450 Ohm and 650 Ohm.

The use of a polarisation network is recommended, to ensure a stable network. Usually the polarisation resistors are

implemented within the master device or they are connectible.

Connect the device at bus topology (line). A stub line must be avoided.

Use a cable 4-core acc. to the EIA485 recommendations:

Impedance 135…165Ω @ 3…20Mhz

Cable capacity < 30pF/m

Cable diameter > 0,64mm

Cable cross section 0,34 mm2 / AWG 22

Loop resistance < 110Ω/km

Shielding Braided shield /shield foil

Cable length 38400 Baud ≤ 1200m

Observe maximum permitted supply voltage Us at the terminals L+/L-:

• Us = 6…35VDC

5 Operation

The parameterization and operation can be made by the integrated wired interface, dependent on the electronic variant.

Knowledge concerning the communication technology is provided.

5.1 Electronic output 09-A – 4…20mA, FSK interface

Conguration and data transmission can be made per standard FSK interface (e.g. isHRT USB resp. isHRT USBeX) and

operating software (e.g. PACTware). The use of the DTM isHRT CommDTM resp. ICS Generic HART DTM is recommended.

Information’s for installation resp. using the FSK interface resp. the operating software are not content of this manual.

Note: Damping:

• At a set damping 0s…<1s the communication is only active for 20s after power-up the supply voltage. After establishing

the connection it will be stay active. While this, the damping is set to 1s. After 4 minutes of inactivity the connection will

be terminated and the damping is reset to the set value.

• At a set damping of ≥ 1s the establishing of a communication connection is always possible.
