    GV/WARREN - DLS-6021 Thermulator - Air velocity and temperature sensor TO-3

    $16.50

    Temperature switch, sensor. Air velocity, 440 FPM/52CThe "Thermulator" - dual logic sensing switch. Warren G-V�s new thermal emulator or "Thermulator" is a self-contained switching device that monitors both rising temperature and reduction of air velocity. It provides two separate preset alarm logic outputs. This unique device provides "minor" alarms if air velocity decreases or temperature rises beyond pre-determined limits and "major" alarms if the malfunction continues, permitting alarming or equipment shutdown. Protects against potential overheating in electronic equipment cooled by forced air. The airflow provides a minor alarm signal if either air velocity drops or temperature increases beyond set limits. Major alarms alert the operator to shut down the system should conditions worsen. Thermulator can be set to operate between 30 and 60�C, and over an airflow range of 50-1,000 FPM. Case: TO-3 4-Pin steel. http://www.radiodetection.com/doclib/SPX_DLS_Series_en.pdf Learn More
