Optical Liquid Level Switches

• Detect almost any liquid: oil or water based
• Fast & reliable detection with a very small amount of liquid
• Intelligent switching behaviour to work in different environments
• Low cost optical technology
• Designed to replace competitor sockets
• Ability to rapid prototype with customisation for electronics, switching

behaviour, environmental sealing and terminating cables/connectors

• Wide variety of power-supply, mechanical format and output options

Detects the presence and absence of liquid by loss of infra red signal refracted into liquid

How do Liquid Level Switches Work?

Designed to fit into small spaces (only the tip has to be in contact) No moving parts to fail - solid state Electronics suited to directly drive and switch equipment

In Liquid: Infra-red light is refracted out of the cone leaving less energy to reach the detector In Air: Infra-red light is reflected back to the detector

The amount of received light is measured to determine if the sensor is in air or liquid

Level Indication

Gas monitoring and control systems ensure a clean, healthy environment; from domestic houses and apartments to factories and other industrial facilities

Zirconia O2 Sensors

• 0.1 – 100% range O2 sensors
• Wide range of application specific formats

with digital and analogue output options

• No reference gas required
• Proven, very stable technology
• Closed loop sensing principle allows a failsafe

‘heartbeat’ operation

• Suitable for aggressive, high temperature,

high pressure and high humidity environments

• Suited to aggressive, harsh environments and

gas streams

• Simple, single point calibration
• Long operating life due to non-depleting

sensor cell technology

We are different to other zirconia sensors on the market: The sensors operating principle uses two mechanisms of stabilised zirconia to measure the partial pressure of oxygen (ppO2) Their unique construction supply a time based output that allows for benefits over others Learn more on AN0043
