Pressure sensors, transducers, and pressure transmitters are essential instruments in a variety of industrial and process applications. The SSCDANT015PGAA3 (hereafter referred to as the DANT015PGAA3) is an example of one such instrument. It is a high accuracy digital pressure transducer that is capable of accurately converting pressure signals to a 4-20mA output and transferring it to a digital controller. It is designed to measure static or dynamic pressure from 0 psi up to 2,000 psi.

Before examining the DANT015PGAA3’s application field and working principle, it is important to understand basic concepts of pressure, pressure sensors, transducers, and pressure transmitters. Pressure can be defined as the force applied to a surface per unit area, and is measured using a variety of units like Pounds per Square Inch (PSI), Bars, and Torr. Pressure sensors are devices that create an electrical signal in response to a change in pressure, creating a pressure-sensing element within a mechanical system. Transducers are electronic devices that transform one energy type, such as pressure, into another form, such as electrical signals.

The DANT015PGAA3 is a pressure transducer that utilizes a strain gauge bridge circuit to convert mechanical pressure to electrical current. It is designed to measure static and dynamic pressure up to 2000 psi with an accuracy of 0.5% full scale. It is also equipped with amplified output circuitry, allowing the pressure measurement to be transferred to a digital controller without the need for additional signal conditioning. Additionally, the device is made of stainless steel, allowing it to operate in a wide range of temperatures from -10C to +60C.

The application field of the DANT015PGAA3 ranges from liquid and gas pressure measurement in the chemical and petrochemical industries to level sensing in water and wastewater treatment. The device is ideal for applications where high accuracy and reduction of parts cost are important factors. It can also be used in industrial plants as a pressure monitor or for precise control and monitoring of both gas and liquids in a process.

The working principle behind the DANT015PGAA3 is as follows. As pressure is applied to the sensor’s diaphragm, the strain gauge bridge circuit is activated and changes its resistance accordingly. This resistance change is then amplified and converted to a 4-20mA electrical signal which is then transmitted to the digital controller. This signal is proportional to the applied pressure, allowing for accurate and efficient pressure measurement.

In conclusion, the DANT015PGAA3 is a highly accurate pressure transducer for measuring static or dynamic pressure up to 2000 psi. It utilizes a strain gauge bridge circuit to convert mechanical pressure to electrical current, allowing for a 4-20mA analog output to be sent to a digital controller. Its stainless steel construction and wide temperature range make it an ideal device for measuring liquid and gas pressure in chemical and petrochemical industries, as well as level sensing in water and wastewater treatment.
