The SST Philosophy
Our primary goal is to deliver sensing solutions that precisely meet our customers’ technical, commercial, and regulatory requirements. This is achieved through a comprehensive standard product portfolio, complemented by the ability to develop customer-specific sensor solutions where standard specifications are not suitable.
SST Sensing identifies the most appropriate sensing technology and uses it as a proven building block to deliver reliable, high-performance, and cost-effective bespoke solutions. This approach ensures optimal performance, reduced development risk, and faster time to market for our customers.

Customization Capability
At SST, we recognize that many applications demand more than an off-the-shelf solution. Our application engineers work directly with customer engineering teams to provide expert technical guidance and tailored design support.

With extensive in-house engineering and manufacturing capabilities, SST can customize standard products to meet exact application requirements. This includes:

•    Modifying electronics, firmware, and signal outputs
•    Adapting housings, materials, and thread styles
•    Adding cabling, connectors, or overmoulded assemblies
•    Enhancing environmental protection for harsh or hazardous conditions

This flexibility allows customers to integrate SST sensors seamlessly into their systems with confidence.

Technical Support & Engineering Expertise
SST’s technical department is comprised of highly experienced and qualified engineers who work closely with customers throughout the project lifecycle. From initial application assessment through to deployment and long-term support, our engineers provide practical, application-driven guidance to ensure optimal sensor performance and reliability.
This collaborative approach enables SST to support both high-volume OEM programmes and highly specialised applications with equal focus and professionalism.

Quality, Growth, and Customer Commitment
SST Sensing employs over 60 people and continues to grow as demand for high-quality, application-specific sensing solutions increases. Our success is built on a strong commitment to customer satisfaction, technical excellence, and continuous improvement.

As an ISO 9001:2015 certified organisation, SST designs, manufactures, customises, and configures sensors and switches for gas and liquid measurement to consistently high-quality standards.
