Title: Alexander Gelbman: Innovator in Temperature Control Technology
Introduction
Alexander Gelbman is a notable inventor based in Gaithersburg, MD (US). He has made significant contributions to the field of temperature control technology, holding a total of 2 patents. His work has been instrumental in advancing the efficiency and reliability of temperature monitoring systems.
Latest Patents
One of Gelbman's latest patents is a computational module for a digital temperature controller. This innovative temperature control assembly is designed for use in centrifugal chemical treatment apparatuses. It features a temperature monitoring thermistor and a rotor heater, with the heater being energized from a power source through a solid-state relay. The thermistor is connected in a temperature Wheatstone bridge, which delivers a voltage signal to a digital voltmeter. The digital voltmeter generates a binary output that is compared in a computer with a digital command signal from a keyboard unit. This computer output controls a variable duty cycle multivibrator stage, providing a relay-operating signal based on the difference between the keyboard command temperature and the digital voltmeter output signal. The system is designed to ensure safety by holding the relay open if forbidden signals are received, such as incorrect polarity or over-range signals.
