Частые вопросы
- Какой датчик выбрать для агрессивных жидкостей?
- Для агрессивных сред подходят VEGAPULS 61 (полностью инкапсулированная антенна PVDF), VEGAPULS 63 (инкапсулированная антенна PTFE/PFA/PVDF, гигиенические исполнения) и VEGAPULS 65 (стержневая антенна в оболочке из PVDF или PTFE).
- Можно ли измерять уровень в узкой трубе или байпасе?
- Да. По таблице размерирования VEGAPULS 62 и 63 работают в успокоительных трубах и байпасах DN 50–DN 100; для продуктов с низкой диэлектрической проницаемостью (εr ≥ 1,6) рекомендуется измерение в успокоительной трубе.
- Чем отличается VEGAPULS 64 от остальных?
- Он работает в W-band на частоте 80 ГГц с очень узким лучом, что даёт малое процессное присоединение, точность ≤ 1 мм и надёжную работу при пене, волнах и конденсате; диапазон до 30 м.
- Какие протоколы передачи данных поддерживаются?
- 4…20 мА/HART (двух- и четырёхпроводное исполнение), Profibus PA, Foundation Fieldbus, а также Modbus RTU и протокол Levelmaster.
- Как настроить датчик удалённо?
- Через внешний пульт VEGADIS 81 (до 50 м от датчика) или VEGADIS 82 (врезается в сигнальную линию в любой точке), по радиоканалу через модуль PLICSMOBILE, либо по Bluetooth со смартфона/ПК через PACTware/DTM.
- Какой корпус выбрать для тяжёлых условий?
- Корпус из нержавеющей стали 316L (однокамерный полированный или двухкамерный прецизионного литья) — для агрессивных сред и экстремальных механических нагрузок, со степенью защиты до IP 66/IP 68 (1 бар).

Take note of safety instructions for Ex applications
29019-EN-180913
Please note the Ex specific safety information that you can find at www.vega.com and that comes with each instrument. In hazardous areas
you should take note of the appropriate regulations, conformity and type approval certificates of the sensors and power supply units. The sen-
sors must only be operated on intrinsically safe circuits. The permissible electrical values are stated in the certificate.

Measuring principle
1 Measuring principle
Measuring principle VEGAPULS WL 61, 61, 62, 65, 66
Extremely short microwave pulses are transmitted by the antenna system
to the measured product, reflected by the product surface and received
back by the antenna system. The time from emission to reception of the
signals is proportional to the level in the vessel. A special time stretching
procedure ensures reliable and precise measurement of the extremely
short transmission periods and the conversion into level.
The radar sensors operate with low emitted power in the C and K band
frequency range.
Measuring principle VEGAPULS 64
The sensor emits a continuous, high frequency radar signal through
the antenna. The emitted signal is reflected by the product surface and
received as an echo by the antenna.
The difference between the emitted and received signal is determined by
special algorithms in the sensor electronics and converted into level.
The VEGAPULS 64 operates with low emitted power in the W band
frequency range.
Applications in liquids
Low frequency C band sensors are used for continuous level measure-
ment of liquids under difficult process conditions. They are suitable for
applications in storage tanks, process vessels or standpipes and can be
used universally thanks to the different antenna versions.
The high frequency K band sensors are universally implementable for
continuous level measurement of liquids. They are suitable for level
measurement in storage containers, reactors and process vessels, even
under difficult process conditions. With the various antenna versions and
materials, they are the optimal solution for almost all applications and
processes.
The high frequency W band sensors are suitable for continuous level
measurement of liquids. The small process fittings offer particular ad-
vantages in small tanks or tight mounting spaces. The very good signal
focusing ensures the use in vessels with many installations such as stir-
rers and heating spirals.
Advantages
Non-contact radar technology is characterized by extremely high accura-
cy. The measurement is influenced neither by fluctuating product features
nor by changing process conditions such as temperature and pressure.
Input variable
The measured quantity is the distance between process fitting of the sen-
sor and product surface. Depending on the sensor version, the reference
plane is the seal surface on the hexagon or the lower side of the flange.

Installation position Acid tank
The sensor is mounted in a position which is at least 200 mm (7.874 in)
away from the vessel wall. If the sensor is installed in the center of dished
or round vessel tops, multiple echoes can arise. However, these can be
suppressed by an appropriate adjustment.

A non-contact measuring principle is particularly suitable for level meas-
urement in acid tanks.
VEGAPULS 61 is characterised by a small process fitting and a PVDF
encapsulated antenna. The sensor is insensitive to temperature fluctua-
tions and gas phases.
Reactor
Fig. 25: Level measurement in the pump shaft with VEGAPULS WL 61
The strongly focussed measuring signal of VEGAPULS WL 61 offers
considerable advantages particularly in tight spaces. The sensor oper-
ates reliably even with foam and buildup on the shaft wall.
Fig. 27: Level measurement in a reactor with VEGAPULS 62
For the production of resins, different basic substances are mixed with
solvents and a reaction is caused by adding process heat.
Non-contact measurement with the radar sensor VEGAPULS 62 is ideal
for use in the production of reaction products. Since the measurement
is performed without direct contact to the medium, virtually no buildup
forms on the sensor.

resistant, even with dynamic pressure and suctions.

Fig. 31: Level measurement in a storage tower with VEGAPULS 65
The VEGAPULS 66 radar sensor is particularly suitable for level meas-
urement in a storage tower for paper suspension.
With the large anntenna and the low frequency measuring system, the
sensor functions even in case of steam and fluctuating surface.
Fig. 29: Level measurement in a small process vessel with VEGAPULS 64
The strongly focussed measuring signal of VEGAPULS 64 offers con-
siderable advantages particularly in small process vessels in the food
processing industry. The sensor operates reliably even with frequently
changing filling and emptying processes.

Voltage supply
If a reliable separation is required, the power supply and the current
output are transmitted over separate two-wire connection cables.

Connection cable
The 4 … 20 mA current output is connected with standard two-wire
cable without screen. If electromagnetic interference is expected which
is above the test values of EN 61326 for industrial areas, screened cable
should be used.
For voltage supply, an approved installation cable with PE conductor is
required.

If screened cable is required, we recommend connecting the cable
screen on both ends to ground potential. In the sensor, the screen must
be connected directly to the internal ground terminal. The ground terminal
on the outside of the housing must be connected to the ground potential
