Platinum SMD Sensor Elements

Heraeus - Manufacturer of Platinum SMD sensors Pt100 Pt1000Heraeus manufacture a wide selection of platinum temperature sensors for diverse industries, measuring temperatures, regulating heating systems and compensating for temperature fluctuations at component level.

Originally manufactured with lead-wires for p.c.b. mounting and use in sensor assemblies, the need for true surface mount Pt100 or Pt1000 sensors led to the development of various SMD forms.  Originally available in a 1206 size chip, as electronic components got smaller and smaller, the chip sizes of our Pt elements also shrank so that today we can offer Pt100s and Pt1000s in 0805 and 0603 formats as well.

These SMD thin film RTD platinum elements offer quick, low-cost and easy automated p.c.b. mounting for volume applications such as data loggers, automotive and medical electronics.  They also offer excellent cold-junction compensation in measuring circuits where thermocouples are the preferred end sensor type.

There are a choice of sizes, together with AEC-Q200 automotive qualified versions, supplied on tape/reel.  Customised solutions are also available and can be produced in large volume with competitive pricing.

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.
