EN 650.5 Fluid Level Indicators with Electrical Oil Level and Temperature Monitoring Metric Size


ELESA original design
code: HCX-E-ST

Product description


EN 650.5 (Elesa® original design) fluid level indicators not only allow fluid levels to be viewed, but can also trigger an electric impulse when oil level drops below a certain point or if a certain temperature is reached.

The oil level is measured by means of a float with a magnet, which makes or breaks a contact (REED switch) when the fluid level is reached.

The temperature is monitored via a sensor, which makes or breaks a contact when a temperature of 175°F (80°C) is reached.

The polyamide body consists of two parts, welded with ultrasound.

EN 650.5 fluid level indicators can also be used in pressurized containers.
