Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments TRASMETTITORI DI LIVELLO AD ULTRASUONI For continuous level measurement of liquids (even if polluted), mash and paste materials in open or closed vessels, sumps, open channels, drains, etc. Variants of level meter with adjustment by two buttons, or by magnetic pen "Xi" version for usage in explosive areas State indication by two LEDs Current output (4 ... 20 mA), voltage output (0 ... 10 V) or RS-485 Modbus output Wide choice of electric connection via connectors, cable glands or protective conductor While used with horn adapter can be measured also some difficult media (foamy levels, bulk solids, etc.) The RIL330 ultrasonic level meters are compact measurement devices containing an ultrasonic transmitter and an electronic module. Using an transmitter, level meters transmit the series of ultrasonic pulses that spread towards the level surface. The transmitter recuperates reflected acoustic waves that are subsequently processed in the electronic module. Based on the period during which the individual pulses spread towards the level and back, this period is averaged by the electronics that performs temperature compensation and subsequently a conversion to an output current 4 -20 mA, voltage 0 - 10 V or output RS-485 Modbus. The RIL330 ultrasonic level meters are suitable for continuous noncontact level measurement of liquids (water solutions, sewerage water, etc.), mash and paste materials (sediments, sticks, resins etc.) in closed or open vessels, sumps, reservoirs and open channels. In case the level of bulk-solid materials is measured, the measurement range is reduced. All setting-up is done using two buttons positioned in the upper part of the sensor. The level meter is equipped with optical state indication (STATE) and with a setting-up process (MENU). The level meter can output current or voltage signals. They are manufactured in model versions for non-explosive areas (N) and explosive areas (Xi). Measuring range from 0.1m to 1m, plastic PVDF transmitter and plastic body (PP+HDPE),process connection with thread G ¾" Measuring range from 0.2 m to 2m, plastic PVDF transmitter and plastic body (PP+HDPE), process connection with thread G 1" Measuring range from 0.2m to 6m, plastic PVDF transmitter and plastic body (PP+HDPE), process connection with thread G 1 ½ Measuring range from 0.4m to 10m, plastic PVDF transmitter and plastic body (PP+HDPE), process connection with thread G 2 ¼" Measuring range from 0.5m to 20m, with plastic PVDF transmitter and plastic body (PP+HDPE), aluminium alloy flange.

Connection through ISO connector The RIL330 level meter with a G type cable gland are connected to processing (display) units by means of a cable with an outer diameter of 6 to 8 mm (recommended wire cross-section 0.5 to 0.75 mm²), via a detachable ISO connector with inner screw terminals, which is part of the delivery. The connection diagram and the inner view of the connector are shown in Figures on the right. Non-detachable connector IP67 with PVC cable 5 m long can be supplied as an extra optional. Connection diagram of the RIL level meter (variant –I) and inside view of the connector...

Wiring operations shall only be carried out without voltage! Taking into account the potential occurrence of electrostatic discharge on non-conducting parts of the level meter, it is necessary to ground the flange of level meters RIL330–53Xi–20–F, located in an explosive atmosphere, using a ground terminal! It is also necessary to design and take measures to reduce the effects of static electricity to a safe level in the wiring. Installation in explosive atmospheres needs to be carried out in compliance with CSN EN 60079-14 (Electrical installations for explosive gaseous atmospheres – Part...
