CARSON CITY, Nev. — Feb. 15, 2017— Ametherm today introduced a new series of glass-encapsulated thermistors that provide long-term stability and reliability for high-accuracy temperature sensing in automotive and industrial applications. Hermetically sealed, DG series devices eliminate errors in resistance readings due to moisture penetration while offering high operating temperatures and a compact size.
The devices released today provide designers with faster, more accurate, and less expensive alternatives to thermocouples and RTD probes. DG series devices are free from limitations due to solder temperature, which enables them to offer users a wide operating temperature range of -55 °C to +200 °C. With diameters of only 1.5 mm, the devices boast a small size that allows for encapsulation in a variety of housings, such as ring lugs and hex nuts.
DG series thermistors are available in four resistance values at 25 °C — 10 k?, 40 k?, 50 k?, and 100 k? — with tolerances down to ±2 %, a dissipation constant of 3.0 mW/°C, and thermal time constant of 6 s. The devices provide TCRs of -3.9%/°C, -4.40 %/°C, and -4.75 %/°C; beta values of 3500 °K, 3950 °K, and 4200 °K; and 32 AWG dumet wire leads.
The glass-encapsulated thermistors are available direct or through distributors such as Digi-Key and Mouser. Samples and production quantities of the devices are available now, with factory lead times of six to eight weeks. Volume pricing for U.S. delivery starts at $0.41 per piece.
