Description
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.
Features
The transmitter is composed of a ceramic sensor placed in a stainless steel body or a piezoresistive measurement cell and an electronic card on a stainless steel 316L body. The sensor design ensures reliability during 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.
The process connection is an easy-to-install pressure transmitter available as a stainless steel 1/2-inch thread and flange connection.
Working Principle
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.
