Sensor Elements with Lead Wires

Heraeus’ wired sensor elements are designed for attaching lead wires to.  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 C-type elements are best suited for cryogenic applications.

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 M540S “micro-heater” which can be accurately used up to 800deg.C.  Various applications including e-cigarettes and other consumer appliances can use this micro-heater.

We can also provide customer-specific special versions, combined with Heraeus high quality due to decades-long experience, research and development, qualified personnel, internal and external interlinking.  With a range of temperature settings available, these sensors are suitable for many applications, from motor vehicles to household appliances.

Call us today on 01606 871680 to discuss your application’s thermal sensor requirements.  Using our extensive technical knowledge and innovative supplier base, we will work with you to provide the optimum solution for your product.
