A new platinum thin-film resistance temperature detector (RTD) could replace wire wound technology and cut its cost by 50 per cent, it has been suggested.

Developed by Innovative Sensor Technology, the PW and PG versions of the device can achieve DIN 60751 class A accuracy for temperatures ranging from -200C to 600C.

In addition to "outstanding" hysteresis characteristics, the PW series offers a temperature coefficient of 3,850ppm/K, with 3,991ppm/K being achieved by the PG series.

According to the company, the sensors can be manufactured at about half the cost of wire wound technology as they are smaller and involve lower material expenditure.

Furthermore, the reduced size affords greater versatility in terms of packaging and significantly improved response times.

Innovative Sensor Technology, which is based in Wattwil, Switzerland, was established in 1991 and is an ISO 9001-certified company with subsidiaries in the US and Czech Republic.

It also manufactures nickel temperature sensors, which provide solutions for precise temperature measurement applications and operate between -60C and 300C.
