Level Switch
WIKA are leading manufacturers of high quality Level Switches. Made with a number of different features, WIKA Level Switches are perfect for the detection of limit levels in liquids with robust LED screens and light receptors.
Model OLS-C20 Optoelectronic Level Switch
The model OLS-C20 Optoelectronic Level Switches are used for the detection of limit levels in liquids. This is widely independent of physical characteristics, such as refractive index, colour, density, dielectric constant and conductivity. Measurement is also done in small volumes.
The switches consist of an infrared LED and a phototransistor. The light of the LED is directed into a prism. So long as the sensor tip of the prism is in the gas phase, the light is reflected within the prism to the receiver. When the liquid in the vessel rises and wets approximately 2/3 of the glass tip, the infrared lightbeam into the liquid is interrupted and only a small portion reaches the receiver.
Model OLS-S/H Optoelectronic Level Switch
The model OLS Optoelectronic Level Switches are used for the detection of limit levels in liquids. This is widely independent of physical characteristics such as refractive index, colour, density, dielectric constant and conductivity. Measurement is also done in small volumes.
The switches consist of an infrared LED and a phototransistor. The light of the LED is directed into a prism. So long as the sensor tip of the prism is in the gas phase, the light is reflected within the prism to the receiver. When the liquid in the vessel rises and wets approximately 2/3 of the glass tip, the infrared lightbeam into the liquid is interrupted and only a small portion reaches the receiver. This difference is evaluated by the electronics and triggers a switching operation.
Model OLS-C05 Optoelectronic OEM Level Switch
The model OLS-C05 Optoelectronic OEM Level Switch is used for monitoring the level of liquids. The optoelectronic sensor consists of an infrared LED and a light receptor. The light from the LED is directed into a prism which forms the tip of the sensor. So long as the tip is not immersed in liquid, the light is reflected within the prism to the receptor.
Model LSD-30 Electronic Level Switch
The successful design and the excellent functionality of the WIKA switch family were already confirmed by winning the “iF product design award 2009” for the PSD-30 pressure switch.
The robust LED display has been designed using 9 mm high characters (the largest possible) and with a slight incline in order to make reading the level as easy as possible from a long way off. A 14-segment display has been used, since it represents text very well.
