Direct Wire Wound Replacement Through Thin-Film Technology

April 6, 2010

PW and PG series thin-film platinum temperature sensors Through design and material selection efforts, Innovative Sensor Technology has developed a platinum thin-film RTD to directly replace wire wound technology at half the cost.

Class A Rating From -200°C to +600°C

IST’s new PW and PG series thin-film platinum temperature sensors are capable of achieving DIN 60751 class A accuracy in the temperature range of -200°C to +600°C. The PW series features a temperature coefficient of 3850 ppm/K, while the PG series offers a temperature coefficient of 3911 ppm/K. The sensors also feature outstanding hysteresis characteristics.

Wire Wound Performance at Half the Cost

Due to smaller dimensions, the PW and PG series sensors can be manufactured at lower material costs, allowing for the sensors to be offered at half the price of wire wound technology. The smaller thin-film dimensions also lead to packaging versatility and much faster response times than those achieved by wire-wound sensors.
