Measuring principle

The Micropilot is a "downward-looking" measuring system, operating based on the frequency
modulated continuous wave method (FMCW). The antenna emits an electromagnetic wave at a
continuously varying frequency. This wave is reflected by the product and received again by the
antenna.

1 FMCW principle: transmission and reflection of the continuous wave



R Reference point of measurement
D Distance between reference point and product surface

The frequency of this wave is modulated in the form of a sawtooth signal between two limit
frequencies f1 and f2:

A0032017



2 FMCW principle: result of frequency modulation

1 Transmitted signal
2 Received signal

This results in the following difference frequency at any time between the transmitted signal and the
received signal:

Δf = k Δt

where Δt is the run time and k is the specified increase in frequency modulation.

Δt is given by the distance D between the reference point R and the product surface:

D = (c Δt) / 2

where c is the speed of propagation of the wave.

In summary, D can be calculated from the measured difference frequency
determine the content of the tank or silo.

Δf. D is then used to

Measured variable

The measured variable is the distance between the reference point and the product surface. The level
is calculated based on "E", the empty distance entered. Optionally, the level can be converted to other
variables (volume, mass) by linearization (32 value pairs).

The usable measuring range depends on the antenna size, the medium's reflective properties, the
installation position and any possible interference reflections.

To ensure electrical safety:

Do not disconnect the protective connection (6).

‣

Disconnect the supply voltage before disconnecting the protective earth (7).

‣

Connect protective earth to the internal ground terminal (7) before connecting the supply
voltage. If necessary, connect the potential matching line to the external ground terminal (11).

In order to ensure electromagnetic compatibility (EMC): Do not only ground the device via the
protective earth conductor of the supply cable. Instead, the functional grounding must also be
connected to the process connection (flange or threaded connection) or to the external ground
terminal.

An easily accessible power switch must be installed in the proximity of the device. The power
switch must be marked as a disconnector for the device (

IEC/EN61010).

Cable specification

Overvoltage protection

• Devices without integrated overvoltage protection
Pluggable spring-force terminals for wire cross-sections

0.5 to 2.5 mm2 (20 to 14 AWG)

• Devices with integrated overvoltage protection
Screw terminals for wire cross-sections 0.2 to 2.5 mm2 (24 to 14 AWG)

• For ambient temperature TU≥60 °C (140 °F): use cable for temperature TU +20 K.

HART

• A normal device cable suffices if only the analog signal is used.

• A shielded cable is recommended if using the HART protocol. Observe grounding concept of the
plant.

• For 4-wire devices: Standard device cable is sufficient for the power line.

If the measuring device is used for level measurement in flammable liquids which requires the use of
overvoltage protection according to

DIN EN 60079-14, standard for
test procedures 60060-1 (10 kA, pulse 8/20 μs), overvoltage protection has to be ensured by an
integrated or external overvoltage protection module.

Integrated overvoltage protection

An integrated overvoltage protection module is available for 2-wire HART as well as PROFIBUS PA
and FOUNDATION Fieldbus devices.

Product structure: Feature 610 "Accessory mounted", option NA "Overvoltage protection".

Technical data

Resistance per channel 2 × 0.5 Ω max.

Threshold DC voltage 400 to 700 V

Threshold impulse voltage < 800 V

Capacitance at 1 MHz < 1.5 pF

Nominal arrest impulse voltage (8/20 μs) 10 kA

1) The material of the gland is dependent on the housing type; GT18 (stainless steel housing): 316L (1.4404); GT19 (plastic housing) and GT20
(aluminum housing): nickel-coated brass (CuZn).

Accuracy (Sum of non­linearity, nonrepeatability
and hysteresis)

Non-repeatability

1) Add error of the analogous value to the digital value.
If the reference conditions are not met, the offset/zero point arising from the mounting conditions may be

up to ±4 mm (0.16 in). This additional offset/zero point can be compensated for by entering a correction
(parameter "level correction") during commissioning.

Response time

Influence of ambient temperature

The response time can be configured. The following step response times (in accordance with

/ DIN EN IEC 60770-1)

≥1.3 s–1 at U

are when damping is switched off:

≥ 24 V

The measurements are performed according to DIN EN IEC 61298-3 / DIN EN IEC 60770-1

• Digital (HART, PROFIBUS PA, FOUNDATION Fieldbus): average TK = 3 mm/10 K

• Analog (current output):
– Zero point (4 mA): average TK = 0.02 %/10 K
– Span (20 mA): average TK = 0.05 %/10 K

2) According to DIN EN IEC 61298-2 / DIN EN IEC 60770-1, the step response time is the time that elapses after an abrupt change in the input
signal until the change in the output signal has adopted 90% of the steady-state value for the first time.

device must not under any circumstances be mounted closer than 20 cm (7.87 in) to the container
wall.
If the container wall is not smooth (corrugated iron, welding seams, joints, etc.) it is recommended
to maintain the largest possible distance from the wall. Where necessary use an alignment unit to
avoid interference reflections from the container wall.→  29

• Not in the center (2) as interference can cause signal loss.

• Not above the filling curtain (3).

• The use of a weather protection cover (1) is recommended to protect the transmitter from direct
sunlight or rain.

• In applications with strong dust emissions, the integrated purge air connection can prevent the
antenna from becoming clogged .
