Micropilot FMR62

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

CAUTION

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

External overvoltage protection

HAW562 or HAW569 from

Endress+Hauser are suited as external overvoltage protection.

Dead band according to

DIN EN IEC 61298-2 / DIN EN IEC 60770-1:

• Digital: 1 mm

• Analog: 1 µA

Response time

The response time can be configured. The following step response times (in accordance with DIN EN IEC 61298-2

Sampling rate

Response time < 3.6 s

/ DIN EN IEC 60770-1)

≥1.3 s–1 at UB

are when damping is switched off:

≥ 24 V

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.
