THERMAL SUPERVISORS
TelCom's family temperature sensors brushless controllers serve broad spectrum applications. Logic output temperature sensors autonomous, programmable temperature devices that output logic state change when measured temperature high low. Voltage output sensors supply linearized output voltage directly proportional measured temperature. These devices useful thermometer circuits, temperature compensation applications, general purpose replacements older thermistor technology. Serial sensors designed easy interface system processor. Both multidrop single zone sensors available. TelCom's brushless Managers provide temperature-proportional speed control fault detection. These devices extend service life, lower average supply current, reduce noise, protect system from over-temperature related failures.
