Screw and nut electro zinc-plated.
In addition to a visual check, the oil level gauges can also emit an electric signal if the temperature of the liquid inside the container reaches the threshold of 70 °C.
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 contact with alcoholic solutions and hot water.
Temperature range
Maximum operating temperature: 75 °C.
The oil level gauge is secured using two M12 tapped holes or, two 12.2 mm (± 0.2 mm) holes and flange nuts. Centre distance for the fastening holes = L1 ±0.3.
