MAXI LEVEL SWITCH LEVEL WITH 1 FLOAT RIL230 Maxi Level switch for control units Measurement up to 3 meters It can be used for dirty liquids, water, petroleum, cutting oils, and tolerates the presence of metal and ferrous particles, since the float does not hold a magnet and is integral with the rod. The required length can be obtained simply by cutting the steel rod, using an ordinary pipe cutter; or the switching point can be varied by using a float with through hole allowing the required liquid control point to be modified whenever necessary. One float can operate just one Reed (min. or max. level), or two Reeds (min. and empty and extra max. level) thus meeting the most complex needs. Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments Total safety since the electrical part is completely separate in the tank side and perfectly sealed with respect to the external side by means of ultrasonic welding and resin coating of the pins. The nylon-glass body is very strong and very resistant with respect to chemicals, and is ideal as an insulating container for the Reed contacts. The RIL230 come standard with rods suitable for control of a max. measurement of 500 or 1000mm. To obtain specific measurements, refer to the table on the next page. They can be ordered already arranged for the control of predetermined measurements. Possibility of control up to 3 m. Solid road and float in PVC foam Quick and easy adjustment of switching point Possibility of reinforcement with liquids in movement Through float On request the float can be supplied with through hole and therefore be positioned in the required position without having to cut the rod (which can therefore be as long as the height of the tank). If necessary, the liquid control point can be subsequently be modified as required by simply moving the float.

IMPORTANT The electrical characteristics of the reed contacts, given in the descriptive tables, are supplied by the manufacturer. If the level indicator is connected to an inductive, resistive or capacitive load or lamp, permanent or temporary sticking of the contact may occur for particular load values, thus compromising its proper operation. It is advisable to appraise the nature of the load before connecting the level indicator. After identifying the type of load the level indicator will be connected to, a contact protection circuit must be included between the indicator and load,...

CAPACITIVE AND RESISTIVE LOAD Tutti i dati ed i contenuti di questa scheda sono di proprietà esclusiva di Riels Instruments Unlike the inductive load, in this case it is the current peaks caused by the charge and discharge of the capacitances that can cause faults in the reed contacts. When a capacitive load is commutated (e.g. even just the capacity of the cables) a discharge of strength depending on the capacity and length of the cables (considered as a series of resistances) passes through the reed contact. The discharge current can be limited by a resistance in series with a capacitor,...
