Reflector white. Float red, with magnetic element. Screws and nuts electro zinc-plated. 8 L1 L 7 Note: The oil level gauge not only enables the oil level to be viewed but also recorded using a REED switch. If the float element reaches the selected minimum value after the circuit has been closed, the 5 system emits an electric signal. The sensor is located on the sight glass and its height can be 3 adjusted in line with the control requirements for the oil level. The minimum level is around 50 mm from the centre of the lower fastening screw. The reed switch is equipped with a normally open (NO) contact as standard. The maximum pressure is 1 bar. The maximum tightening torque of the fastening screws is 5 Nm. The sight glass has high mechanical strength and is resistant

Function: The oil level is measured using a float element with a magnet that activates the electrical contact when the REED level switch is reached. If the oil level falls below a particular level, an electrical pulse can be emitted. Attention: Strong magnetic fields can impair function. fastening screws
