Optomax Industrial Glass Range of Liquid Level Switches

Optomax industrial glass range of liquid level switches which are often single point, can operate In high pressure, high temperature, aggressive environments due to their stainless steel and glass construction while offering industrial supply voltages and outputs that can directly drive loads.
The microcontroller based Optomax Industrial Glass Range of single point Liquid Level Switches are solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid.

A range of N and P type output configurations can sink or source up to 1A at supply voltage ranges from 4.5 to 15.4Vdc or 8 to 30Vdc and can be configured to output a high or low signal in either a wet or dry state. Options for connecting to inductive loads or digital interfaces are also available.

The 316L stainless steel single point liquid level switch can operate up to 600 bar (8700 psi) with housing threads suitable for external sensor mounting and for use in operating temperature range -40 to 125°C.

Samples for the Optomax Industrial Glass range of liquid level switches are available on request for this product. For high volume production orders, please contact us.

The SST Sensing Philosophy

Our primary goal is to deliver the required sensing and control solutions to our customers which exactly meet their technical and commercial sensor requirements. This can be achieved through our standard range of sensors or providing customer specific sensor solutions. We have been designing and manufacturing fluid and gas sensing solutions for over 15 years. Where a specific solution is required, SST Sensing Ltd will identify the suitable technology and use this as a building block to provide a bespoke customer solution.

Technical Support

Our technical department is comprised of highly experienced and qualified engineers who work extensively with our customers to ensure their requirements are met. Our engineers work with customers to provide full application and technical support if required.

SST now has over 60 employees and our success is growing day by day. The core of this success is due to our strong commitment to our customers. Therefore, we want to ensure that our customers feel valued at all times.

Quality Products

As an ISO 9001:2015 certified organisation, SST manufacture, design, customise and configure a range of sensors and switches for gases and liquids.

Within our vast range of standard product offerings you will find; miniature, solid state optical liquid level switches; rugged, robust and reliable Zirconium Dioxide oxygen sensors; factory calibrated optical oxygen sensors that measure ambient oxygen levels and finally carbon dioxide sensors which are powered using energy harvesting technology.

Customisation

At SST we understand that customer needs vary and can be very specific. SST’s application engineers work directly with our customers’ engineers to provide application and technical support. SST have the in-house ability to take any of our standard range of sensors and customise it to your exact specification if the standard spec is unsuitable.

Whether that be adding or modifying electronics and software, changing outputs, adapting housing or thread styles, adding cabling, connectors or environmental protection.
