Optical Level Switches
An optical level switch works by emitting a beam of infrared light
within a prism and measuring the amount of light received. When the
measured fluid reaches the sensor the amount of emitted light received
drops thus triggering the contacts. As the sensor is detecting the state
between material covering or not covering the prism it can be used to
detect the presence or absence of fluid thus preventing damage to
pumps.
The compact unit houses the infrared transmitter, the prism, the receiver
and the electronics, there is also an external LED indicator to
show the condition of the switch. The sensor requires a power supply
of between 10-28 Volts Dc. The benefit of the modern optical sensor is
that there are no moving parts that can retain material and get
clogged up or damaged, simply fit and forget.
Our new range of optical level switches are second to none when it comes to quality and reliability. All units have hermetically sealed electronics with cable entry rated at IP68, an LED status indicator to confirm at a glance the condition of the switch, a standard 2 metre cable with pre stripped and tinned leads. As with most of our products we can offer customisation to your specific requirement, whether it is longer leads, crimped terminals or special connectors, just call and tell us what you need. The main benefit of an optical level sensor over the more common float switch is that there are no moving parts to get clogged up or damaged, just fit and forget. We also have high temperature stainless steel models for harsh environments and use in the food industry.
