Siegert Thinfilm Technology

What Siegert Thinfilm Technology does

Siegert Thinfilm Technology GmbH (Siegert TFT) is a Hermsdorf, Thuringia-based manufacturer of thin-film sensor elements founded in 1992 as a spin-off from Keramische Werke Hermsdorf. The company specializes in sputtering thin-film strain gauges and resistive circuits directly onto stainless steel and specialty alloy membranes (17-4 PH, 316L, Hastelloy C22, Inconel 718), eliminating adhesive layers to deliver high long-term stability and minimal drift. Production is conducted in a 650 m² clean room within a 6,500 m² facility, and the firm is ISO 9001:2015 and ISO 50001:2018 certified. The portfolio spans standard and customized pressure sensor series (PSP/PSF lines for general, extended-temperature up to 200°C, highly media-resistant, high-output, hydrogen-compatible, and front-flush applications), weldable force sensor elements (SGI/SGU), and SMD/bondable temperature sensors (TRS), plus precision resistor networks and substrate functional coatings.

The company sells exclusively through a direct B2B field-sales motion aimed at engineering and technical buyers. Customers integrate Siegert's elements into their own products, either as bare sensor elements or pre-mounted on customer-specific pressure ports and strain bodies. Targeted verticals include industrial automation and measurement technology, hydraulics, aerospace, high-frequency electronics, oil and gas, chemical process, offshore/maritime, and hydrogen applications. Revenue is generated through hardware sales and engineering-driven custom development services, with quote-based pricing and no public list pricing. Siegert is a subsidiary of Hydac Electronic GmbH and collaborates with Micro-Hybrid Electronic, CiS Forschungsinstitut für Mikrosensorik, and 5microns on the AMA Innovation Award-winning HermeSEAL hermetic-sealing platform for NDIR gas sensors. As of 2025, the firm has over 130 employees and continues to invest in capacity expansion, adding a second coating system in late 2023 and participating in university recruiting and TRIDELTA Campus ecosystem activities.

Core offering

Siegert TFT develops and manufactures thin film sensor elements for pressure, force, and temperature measurement by depositing thin film strain gauges and resistor structures directly onto stainless steel and special alloy membranes (such as 17-4 PH, 316 L, Hastelloy C22, and Inconel 718). Products are supplied as standard sensor series (PSP, PSF, SGI, SGU, TRS) or as customer-specific sensor elements welded onto pressure ports and strain bodies, with custom development services for integration into industrial customer applications. In-house clean room manufacturing covers everything from samples to mass production.

Product overview

Siegert Thinfilm Technology is a thin film technology company specializing in the development and manufacturing of complex electronic components and systems. Their product portfolio centers on three main sensor categories: pressure sensors (including standard, extended temperature, media-resistant, high-signal, hydrogen-compatible, and front-flush variants), force sensors (weldable elements for integration into strain beams), and temperature sensors. All products utilize thin film technology applied directly to stainless steel or specialized alloy membranes, featuring Wheatstone bridge configurations for high precision measurement. The company produces both standard product series (PSP, PSF, SGI, SGU, TRS) and offers customer-specific customization.
