Sensor Coating Systems

Sensor Coating Systems (SCS) is an instrumentation company pioneering high definition thermal mapping. SCS' Thermal History Technology provides a unique luminescence based sensing technology which enables engineers to record past temperatures on a previously inaccessible components. The temperature measurement capability reaches from around 150°C to 1,400°C which makes the technology very useful for the evaluation and design of mission-critical components in harsh environments such as gas turbine blades or vanes [1]. The company’s unique thermal history technology has received numerous awards since its development with application possibilities in the power generation, aerospace, automotive, oil & gas sectors, as well as opportunities for other relevant high temperature industrial applications.

Sensor Coating Systems spun out of Southside Thermal Sciences (STS) in 2012, after identifying that STS’ future product development focus should be on a smart offline temperature-sensing technology, while SCS concentrates on the development of offline temperature-sensing technologies. Sensor Coating Systems' technology was originally developed by a team at Imperial College London. Since then, the company has received several awards[2][3][4][5] as well as grants from government entities such as Innovate UK and the National Aerospace Technology Exploitation Programme (NATEP).


SCS has developed two offline temperature measurements: The Thermal History Coatings and Thermal History Paint. These technologies utilise the luminescent properties of materials to provide information on past temperatures that components were exposed to. The patented technology allow for the readout of past temperatures from a continuous surface, enabling the thermal analysis of components. Both Thermal History Paint and Thermal History Coating, have been operated in extreme conditions, examples including jet engines and industrial gas turbines [6][7].

The table below shows the differences between the Thermal History Coating and the Thermal History Paint:

Characteristics Thermal History Paint Thermal History Coating
Temperature range 150 to 1,000°C 500 to 1,400°C
Application Air spray APS (Atmospheric Plasma Spray)
Durability Medium High
Thickness 0.03 mm 0.03 mm
Hazardous Materials None None
Measurement's accuracy between ±5-10°C between ±5-10°C

The thermal history coating (THC) is a robust coating containing various non-toxic chemical compounds whose crystal structures irreversibly change at high temperatures. The Thermal History Coating is applied by air plasma spraying, an industrial standard process. The thermal history paint (THP) is less durable than the THC and can be applied with an air spray gun.

At the beginning of 2018, SCS started a project with NASA and other companies working in the aerospatial industry. This project called CoAtings for Ultra high-Temperature detectION (CAUTION) has the aim to increase the temperature range of the Thermal History Coating. Such improvements can help end-users to develop new jet engines with higher efficiencies [8]. Other potential application areas are in predictive maintenance and services.

User clubEdit

In February 2013, SCS announced the formation of an industrial “User Club” to promote the development of its patented temperature-sensing technology, the Thermal History Coating. The User Club was initially launched with four members in addition to SCS [9]. The aim of the User Club is to catalyse the development of the Thermal History Coating, so that they can be applied in engine development programs to lower costs and accelerate the introduction of low-emission engines.
