Sensor Elements with Lead Wires

Heraeus - Manufacturer of platinum sensorsHeraeus’ wired sensor elements are designed for attaching lead wires to, and the range of designs available will ensure a product is available for your application.

M-type platinum elements are the best choice for most general applications. L-type series elements are constructed with AgPd lead wires which are suitable for soft-soldering. The HM, HL, and HD-type elements provide an extended high temperature operating range, whereas the C-type elements are best suited for cryogenic applications.

Their key features of maximum precision, long-term stability and high resistance combined with an availability of a range of temperature settings, make these platinum thin film temperature sensors the ideal sensor across a number of applications, from automotive to household appliances.

In particular, these wired platinum elements can also be used as miniature heating elements for use in low air-flow applications such as aspirating smoke detectors.

Heraeus have also developed the dedicated H540S “micro-heater” which can be accurately used up to 800°C.  Various applications including e-cigarettes and other consumer appliances can use this micro-heater.

We can also provide customer bespoke versions.
