CAUTION!

... indicates a potentially dangerous situation that can result in light injuries or damage to property or the environment, if not avoided.

Information

... points out useful tips, recommendations and information for efficient and trouble-free operation.

3.2 Intended use

The reference pressure sensor serves for the accurate determination of the pressure value. The measured pressure is output as an electrical signal.

Only use the reference pressure sensor in applications that lie within its technical performance limits (e.g. max. ambient temperature, material compatibility, ...). For performance limits see chapter 9 “Specifications”.

The instrument has been designed and built solely for the intended use described here, and may only be used accordingly.

The technical specifications contained in these operating instructions must be observed. Improper handling or operation of the instrument outside of its technical specifications requires the instrument to be taken out of service immediately and inspected by an authorised WIKA service engineer.

The product passport can be retrieved from the product page , directly from the corresponding web application (https://portal.wika.com/serial/) or via the QR code on the product label.

4. Transport, packaging and storage

4.1 Transport

Check the reference pressure sensor for any damage that may have been caused by transport. Obvious damage must be reported immediately.

CAUTION! Damage through improper transport

With improper transport, a high level of damage to property can occur.

▶

When unloading packed goods upon delivery as well as during internal transport, proceed carefully and observe the symbols on the packaging.

▶

With internal transport, observe the instructions in chapter 4.2 “Packaging and storage”.

If the instrument is transported from a cold into a warm environment, the formation of condensation may result in instrument malfunction. Before putting it back into operation, wait for the instrument temperature and the room temperature to equalise.

4.2 Packaging and storage

Do not remove packaging until just before mounting. Keep the packaging as it will provide optimum protection during transport (e.g. change in installation site, recalibration).

Permissible conditions at the place of storage:

■

Storage temperature: -20 ... +80 °C (-4 ... +176 °F)

■

Humidity: 0 ... 95 % relative humidity (non-condensing)

Avoid exposure to the following factors:

■

Direct sunlight or proximity to hot objects

■

Mechanical vibration, mechanical shock (putting it down hard)

■

Soot, vapour, dust and corrosive gases

■

Hazardous environments, flammable atmospheres

Store the instrument in its original packaging in a location that fulfils the conditions listed above. If the original packaging is not available, pack and store the instrument as described below:

1. Wrap the instrument in an antistatic plastic film.

2. Place the instrument, along with the shock-absorbent material, in the packaging.

3. If stored for a prolonged period of time (more than 30 days), place a bag containing a desiccant inside the packaging.

4. Transport, packaging and storage

5. Commissioning, operation

Personnel: Skilled personnel Protective equipment: protective gloves Tools: Spanner or torque spanner

Only use original parts (see chapter 10 “Accessories”).

WARNING! Physical injuries and damage to property and the environment caused by hazardous media

Upon contact with hazardous media (e.g. oxygen, acetylene, flammable or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic, radioactive), and also with refrigeration plants and compressors, there is a danger of physical injuries and damage to property and the environment. Should a failure occur, aggressive media with extremely high temperature and under high pressure or vacuum may be present at the instrument.

▶

For these media, in addition to all standard regulations, the appropriate existing codes or regulations must also be followed.

5.1 Mounting the instrument

WARNING! Physical injury through aggressive media, high pressures and high temperatures

When mounting, there is a danger from aggressive media, high pressures and high medium temperature.

▶

Observe the information in the material safety data sheet for the corresponding medium.

▶

Connect the pressure sensor once the system has been depressurised.

▶

At medium temperatures above 65 °C (149 °F) wear protective gloves.

Only use the pressure transmitter if it is in perfect condition with respect to safety. Prior to commissioning, the pressure transmitter must be subjected to a visual inspection.

■

Leaking fluid is indicative of damage.

5.2 Requirements for mounting point

The mounting point must meet the following conditions:

■

Ambience corresponds to a max. pollution degree of 3.

■

Humidity ≤ 80 % r. h. (non-condensing).

■

Protected from weather influences.

■

Sealing faces are clean and undamaged.

5. Commissioning, operation

WIKA operating instructions, reference pressure sensor, model CPT7000

14210181.02 04/2019 EN/DE

■

Sufficient space for a safe electrical installation.

■

For information on tapped holes and welding sockets, see Technical information IN 00.14 at www.wika.com.

■

Permissible ambient and medium temperatures remain within the performance limits. Consider possible restrictions on the ambient temperature range caused by mating connector used.

■

For performance limits, see chapter 9 “Specifications”

5.3 Mechanical mounting

The max. torque depends on the mounting point (e.g. material and shape). If you have any questions, please contact our application consultant. For contact details see chapter 1 “General information” or the back page of the operating instructions.

1. Seal the sealing faces.

2. At the mounting point, screw the pressure transmitter in hand-tight.

▶

When screwing in, do not cross the threads.

3. Tighten with a torque spanner using the spanner flats. The maximum torque of the CPT7000 is 50 Nm; for flush connections, 40 Nm.

5.4 Electrical connection

To electrically connect a model CPT7000 to the CPH7000 process calibrator, the corresponding plug connection of the cable must be plugged in at the sensor. To connect it to the CPH7000, the other end of the cable must also be plugged in.

1. To connect or change the reference pressure sensor, must not switch off the CPH7000 process calibrator.

2. Connect the process calibrator and the reference pressure sensor to each other electrically using a separate sensor connection cable. Use the 7-pin plug contact on the pressure sensor for this.

3. Connect the 7-pin connector to the reference pressure sensor in accordance with the orientation guide and secure it through the connection sleeve. Turn the connection sleeve clockwise without much force.

4. Connect the 6-pin M-DIN connector to the process calibrator on channel 1 or channel 2 in accordance with the orientation guide.

5. Commissioning, operation

WIKA operating instructions, reference pressure sensor, model CPT7000

14210181.02 04/2019 EN/DE

When connecting the sensor connection cable to the hand-held, the pressure sensor’s connector might not locate properly in the socket. In this event you should try holding the connector by the bend protection, rather than by the connector sleeve.

▶

Connect the connector without tilt the threads.

⇒

If the connector is positioned correctly, it can be plugged in without any significant effort.

▶

To disconnect the pressure sensor, do not pull on the sensor connection cable, but rather only on the connector sleeve.

The voltage supply is provided via the model CPH7000 process calibrator.

6. Faults

Personnel: Skilled personnel Protective equipment: protective gloves Tools: Spanner or torque spanner

WARNING! Physical injuries and damage to property and the environment caused by hazardous media
