SENSING ELEMENTS

In-house thin-film technology
Connections by means of bonding or direct soldering of flexible wires
Highly robust
Variants for hydrogen and other aggressive media
Customized solutions

Typically, the OPTI and OEM stainless steel sensing elements are welded onto stainless steel pressure adaptors. The OPTI and OPTI H2 sensing element is connected to the adaptor via bonding and can also be delivered pre-welded onto an adaptor. For its electrical connections, the OEM sensing element uses robust colorcoded leads. In the standard program, sensors are mounted on G1/4” adapter parts. Application-specific versions are also available, featuring a range of pressure connections. OPTI and OEM sensing elements cover a temperature range of -40…+200°C / -40…+392°F. Produced in compliance with standards DIN EN 60770-1 and DIN EN 60068-2-80, they are highly robust. The OPTI-H2 sensing element covers a temperature range of -40...+130 °C / -40...+266 °F. The cells are ideal for use in hydraulic systems, hydrogen applications and test setups.
