OLT optical liquid level switches

First Sensor OLT optical liquid level switches use solid state technology with no moving parts for highly accurate and reliable measurements. The sensors plastic TROGAMID® housings provide high chemical resistance and excellent media compatibility. With their miniature threaded housings the OLT sensors are easy to install and consume little space. The OLT series can be used with many liquids which are not compatible with conventional polysulphone housings such as fuel, halogenated hydrocarbons (e.g. chloroform), methanol, acetone and ethyl acetate. Furthermore, TROGAMID® can also be used in direct contact with food and drinking water.
