Application
GPT series pressure transmitters are devices that measure the relative and absolute pressure of liquids, gases and steam in many industries such as chemical, pharmaceutical, food industries and water distribution networks.

Design
The transmitter consists of a ceramic sensor placed in a stainless steel body or a piezoresistive measuring cell and electronic card on a stainless steel 316L body. The sensor design ensures that reliability is maintained in temperature changes and overload. The use of a stainless steel 316L diaphragm or ceramic sensor ensures high linearity over the entire measuring range, while minimizing the hysteresis effect. It is an easy-to-install pressure transmitter that can be used as a process connection stainless steel 1/2 inch threaded and flanged connection.

The way it works
Stainless steel 316L diaphragm and ceramic sensor sense the physical deviations of the elements under pressure. Mechanical deformation is transmitted by transforming an electrical signal through the diaphragm and the ceramic sensor with a resistance bridge. An amplifier converts the cell's output voltage into 4-20mA, which is the transmitter's output current signal. The Pressure Transmitter is powered by an external stable power supply. Reverse polarity and high supply voltage are avoided by protection diodes at the input. The device is also not affected by electromagnetic noise thanks to the EMC protective components inside.
