PTU pressure transmitters (hereinafter referred to as the devices) are designed for continuous conversion of overpressure and/or underpressure, pressure difference of liquids, gases and steam into a unified electrical signal of direct current.
The devices can be used to measure various types of pressure depending on their functional purpose and are used in various industries.
The principle of operation of the devices is as follows: the measured pressure is sensed by the membrane of the measuring part and transmitted to the sensing element of the strain gauge. Under the influence of pressure, the elastic element of the strain gauge deforms, changing the resistance of the strain gauges located on it. The electronic module converts this change in resistance into an electrical signal of DC current or DC voltage.
