Thermistor Eliminates Conduction between Leads for Highest Temperature-Sensing Accuracy

April 10, 2018 by Paul Shepard

Ametherm today announced that the company has extended the capabilities of its ACCU-Curve series of interchangeable NTC thermistors with the ACL-011. This new device features insulated tinned-copper leads, ensuring the most accurate temperature sensing with no unintended conduction between leads.

Ametherm's ACL-011 delivers long-term stability and reliability for high-accuracy temperature sensing, control, and compensation in medical, industrial, and automotive applications. The device offers interchangeability over a broad temperature range and eliminates the need to individually calibrate or provide circuit compensation for part variability.

Offering a diameter of 1.524 mm and 32 AWG leads, the epoxy-coated thermistor features resistance at 25 °C of 50 kΩ, with a tolerance of ± 1 %. The ACL-011 offers Beta of 3950 °K, a dissipation constant of 3 mW/°C, maximum power rating of 50 mW, and an operating temperature range of - 40 °C to + 125 °C.

Providing designers with faster, less-expensive alternatives to RTD probes and thermocouples — without compromising on accuracy, Ametherm's ACCU-Curve series thermistors deliver the tight tolerances required for accurate temperature measurement in critical medical instrumentation and can be potted in a variety of housings for temperature compensation circuits in industrial and automotive applications.

The ACL-011 is available direct or through distributors such as Digi-Key and Mouser. Samples and production quantities are available now, with lead times of 12 weeks for large orders.
