Electronic Temperature Sensor for liquids Model TDD

Description

KOBOLD temperature switches of model TDD are used for
economical measurement and monitoring of temperature.
They are suited for applications where temperature must be
monitored with a high degree of switching accuracy. A semi­conductor, which outputs a digital signal to the evaluating
electronics in 0.5 °C steps, serves as sensor element.

The current measured value is displayed on a 3-digit LED
display. Two switch points, on-/off-switching delay and hys­teresis are adjustable within the measuring range.

Applications

 Compressors

 Mechanical engineering

 Plant engineering

 Pumps

Accessories: Electrical Connection
