Note:
- The oil level gauge not only enables the oil level to be viewed but also recorded using a REED switch. In addition, the oil level gauges can also emit an electric signal if the temperature of the liquid inside the container reaches the threshold of 70 degC. B1 As soon as the float element approaches the selected minimum value after H2 the circuit has been closed, the system emits an electric signal. The sensor is located on the housing and its height can be adjusted in line with the control requirements for the oil level. The minimum level is ca. 35 mm from the centre of the lower fastening screw. The reed switch is equipped with a normally open (NO) contact as standard. The temperature is monitored by a temperature switch (bi-metal). When the specified temperature is reached, the sensor closes (NO) or opens (NC) the circuit depending on the model. The sight glass consists of two transparent components which are ultrasonically welded together following assembly. This ensures a seal around the entire body. 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 to mineral oil, petrol, lubricants, petroleum, solvents and most chemical substances. Avoid Attention: contact with alcoholic solutions and hot water. Strong magnetic fields can impair function.
