The ENTUBE DE-HB (750V 5V SESC) is a current/voltage transducer that is designed to measure the absolute or DC voltage between two points in a power system, with a continuous full-scale rated voltage of up to 750V. This unit features a direct output that is proportional to the measured voltage, which can be displayed on either a digital readout or digital oscilloscope. It can also be used to give overvoltage and/or trip signals, and can also act as a grounding monitor for protection systems.

The ENTUBE DE-HB consists of two parts--the sensing element and the signal conditioning circuitry. The sensing element consists of a special ceramic that contains copper wire coils wound on it. When a voltage is applied to the ceramic, an electric field is generated in it, which causes the copper coils to expand or contract in length. This change in length manifests itself as a change in the electrical resistance of the coils, which is then converted to a corresponding voltage in the signal conditioning circuitry. The signal conditioning circuitry takes this voltage and passes it on to the external measurement device for further analysis.

The ENTUBE DE-HB is a simple and reliable device, with no moving parts and a low susceptibility to environmental factors such as temperature and humidity. It is suitable for operation in a wide range of extreme conditions, from -50°C to +105°C. It also has a very low power consumption and is capable of monitoring voltages up to 750V AC/DC at frequencies up to 10MHz.

The ENTUBE DE-HB can be used in multiple applications, such as in transmission and distribution systems to measure the difference between phases and to check the continuity of the neutral line. It can also be used for AC/DC load monitoring, voltage regulation, fault detection, and power factor measurement.

The ENTUBE DE-HB is a very useful and convenient device, which can be used in a variety of applications. It is easy to install and does not require any additional components or power supplies. With its reliable performance and wide range of applications, it is an excellent choice for monitoring and measuring current and voltage in difficult or sensitive applications.
