1.5 Terms and abbreviations

Item Term/abbreviation Explanation

1 OPL The OPL (over pressure limit = sensor overload limit) for the measuring device depends on the lowest-rated

element, with regard to pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. The OPL may only be applied for a limited period of time.

2 MWP The MWP (maximum working pressure) for the sensors depends on the lowest-rated element, with regard to

pressure, of the selected components, i.e. the process connection has to be taken into consideration in addition to the measuring cell. Also observe pressure-temperature dependency. The MWP may be applied at the device for an unlimited period. The MWP can also be found on the nameplate.

3 Product description

3.1 Function

The ceramic measuring cell is a dry measuring cell i.e. the pressure acts directly on the robust, ceramic process isolating diaphragm of the Waterpilot FMX21. Changes in air pressure are guided via a pressure compensation tube through the extension cable to the rear of the ceramic process isolating diaphragm and are compensated for. A pressuredependent change in capacitance, caused by the movement of the process isolating diaphragm, is measured at the electrodes of the ceramic carrier. The electronics unit then converts this to a signal that is proportional to the pressure and linear to the level.

5.2 Additional mounting instructions

• Cable length – Customer-specific in meters or feet. – Limited cable length when performing installation with freely suspended device with

cable mounting screw or mounting clamp, as well as for FM/CSA approval: max. 300 m (984 ft).

• Sideways movement of the level probe can result in measuring errors. For this reason, install the probe at a point free from flow and turbulence, or use a guide tube. The internal diameter of the guide tube should be at least 1 mm (0.04 in) greater than the external diameter of the selected FMX21.

• To avoid mechanical damage to the measuring cell, the device is equipped with a protection cap.

• The cable must end in a dry room or a suitable terminal box. The terminal box from Endress+Hauser provides humidity and climatic protection and is suitable for installation outdoors →  124.

• Cable length tolerance: < 5 m (16 ft): ±17.5 mm (0.69 in); > 5 m (16 ft): ±0.2 %

• If the cable is shortened, the filter at the pressure compensation tube must be reattached. Endress+Hauser offers a cable shortening kit for this purpose →  124 (documentation SD00552P/00/A6).

• Endress+Hauser recommends using twisted, shielded cable.

• In shipbuilding applications, measures are required to restrict the spread of fire along cable looms.

• The length of the extension cable depends on the intended level zero point. The height of the protection cap must be taken into consideration when designing the layout of the measuring point. The level zero point (E) corresponds to the position of the process isolating diaphragm. Level zero point = E; tip of probe = L (see the following diagram).

Engineering unit mm (in). Illustrated with G 1½" thread.

If you want to lower the level probe to a certain depth, position the top edge of the clamping sleeve 40 mm (4.57 in) higher than the required depth. Then push the extension cable and the clamping sleeve into the adapter as described in Step 6 in the following section.

5.5.1 Mounting the cable mounting screw with a G 1½" or NPT 1½" thread:

1. Mark the desired length of extension cable on the extension cable.

2. Insert the probe through the measuring aperture and carefully lower on the extension cable. Fix the extension cable to prevent it from slipping.

3. Slide the adapter (item 5) over the extension cable and screw it tightly into the measuring aperture.

4. Slide the sealing ring (item 3) and cover (item 2) onto the cable from above. Press the sealing ring into the cover.

5. Place the clamping sleeves (item 4) around the extension cable (item 1) at the marked point as illustrated in the graphic.

6. Slide the extension cable with the clamping sleeves (item 4) into the adapter (item 5)

7. Fit the cover (item 2) with the sealing ring (item 3) onto the adapter (item 5) and securely screw together with the adapter.

To remove the cable mounting screw, perform this sequence of steps in reverse.

1 Mounting screws 2 Mounting springs 3 TMT182 temperature head transmitter 4 Circlips 5 Terminal box

Only open the terminal box with a screwdriver.

WARNING

Risk of explosion!

The TMT182 is not designed for use in hazardous areas.

‣

5.7.1 Mounting the temperature head transmitter:

1. Guide the mounting screws (item 1) with the mounting springs (item 2) through the bore of the temperature head transmitter (item 3)

2. Secure the mounting screws with the circlips (item 4). Circlips, mounting screws and springs are included in the scope of delivery for the temperature head transmitter.

3. Screw the temperature head transmitter into the field housing tightly. (Width of screwdriver blade max. 6 mm (0.24 in))

NOTICE

22 Endress+Hauser

Avoid damage to the temperature head transmitter.

Do not overtighten the mounting screw.

5.9 Inserting the cable into the RIA15 field housing

A0017830

Inserting the cable, field housing, connection without transmitter power supply (example)

1. Release the housing screws

2. Open the housing

3. Open the cable gland (M16) and insert the cable

4. Connect the cable including the functional grounding and close the cable gland

Compensation of the atmospheric pressure must be ensured for the installation. A black, vented cable gland is supplied for this purpose.

If using the communication resistor module in the RIA15, the cable of the FMX21 must be inserted into the right gland when connecting the FMX21 so that the integrated pressure compensation tube is not pinched.

Waterpilot FMX21 Installation

• To make installation easier, Endress+Hauser marks the extension cable if a customer-

specific length has been ordered. Ordering information: Product Configurator order code for "Service", option "IR" or "IS".

• Cable marking tolerance (distance to lower end of level probe):

Cable length < 5 m (16 ft): ±17.5 mm (0.69 in) Cable length > 5 m (16 ft): ±0.2 %

• Material: PET, stick-on label: acrylic

• Immunity to temperature change: –30 to +100 °C (–22 to +212 °F)

NOTICE

The marking is used exclusively for installation purposes.

The mark must be thoroughly removed without trace in the case of devices with

‣

drinking water approval. The extension cable must not be damaged in the process.

Not for use of the FMX21 in hazardous areas.

5.11 Cable shortening kit

A0030948

The cable shortening kit is used to shorten a cable easily and professionally.

The cable shortening kit is not designed for the FMX21 with FM/CSA approval.

• Ordering information: Product Configurator order code for "Accessories enclosed", option

"PW"

• Associated documentation SD00552P/00/A6.

5.12 Post-installation check

 Is the device undamaged (visual inspection)?

Does the device conform to the measuring point specifications?

For example:

• Process temperature



• Process pressure

• Ambient temperature

• Measuring range

 Are the measuring point identification and labeling correct (visual inspection)?

 Check that all screws are firmly seated.
