Temperature detector runs up to 850C

A new Pt 100 resistance temperature detector (RTD) is specifically designed for measuring temperatures up to 850C.

A new Pt 100 resistance temperature detector (RTD) is specifically designed for measuring temperatures up to 850C.

The new detector, which is ideally suited for use in high volume applications, offers a low cost alternative to traditional wire wound devices.

It comprises of a laser trimmed, platinum thin film resistor on a ceramic substrate which measures only 3.9 x 2.2mm.

The new HD 421 offers the highest levels of measurement accuracy and long term stability.

It has extremely fast response times and is highly resistant to vibration and shock.

The full operating temperature range is -70 to +850C.

Up to 650C the detector can be fully encapsulated inside temperature sensor assemblies including mineral insulated designs.

At temperatures above 650C it must not be used in a reducing atmosphere so care must be taken to ensure that air is free to enter the detector housing.

The measurement tolerance meets the class B standard of DIN EN60751.
