Viatran 5093BPS pressure sensor, original VATRON product.
The Viatran 5093BPS pressure sensor from Vtron, made in the USA, primarily uses an identification element to sense whether a sample contains the target DNA. The transducer then converts the signal sensed by the identification element into a signal that can be observed and recorded. Typically, a single-stranded DNA molecule is immobilized on the transducer. Through DNA hybridization, it identifies another DNA molecule containing a complementary sequence, forming a stable double-stranded DNA. The target DNA is then detected through the conversion of acoustic, optical, and electrical signals. The principle of a DNA biosensor is that a single-stranded DNA molecule with a known nucleotide sequence immobilized on the surface of the sensor, or transducer probe, hybridizes with another complementary ss-DNA molecule. The resulting double-stranded DNA exhibits a certain physical signal, which is ultimately detected by the transducer.

Most sensors nowadays are moving towards two-wire systems, and data communication is achieved on this basis (e.g., using the HART protocol). Four-wire systems are mostly used for high-power applications. For long transmission distances and explosion-proof applications, passive two-wire sensors are best . The principle of a two-wire transmitter is to use a 4~20mA signal to provide its own power. If the transmitter's own power consumption is greater than 4mA, then it will be impossible to output the lower limit of 4mA. Therefore, it is generally required that the power consumption of a two-wire transmitter (including all circuitry including the sensor) does not exceed 3.5mA. This is one of the fundamental design principles of two-wire transmitters.

From an overall structural perspective, a two-wire transmitter consists of three main parts: a sensor, a conditioning circuit, and a two-wire V/I converter. The sensor converts physical quantities such as temperature and pressure into electrical parameters. The conditioning circuit amplifies, conditions, and converts the weak or nonlinear electrical signal output by the sensor into a linear voltage output. The two-wire V/I converter controls the overall power consumption current based on the output of the signal conditioning circuit; simultaneously, it obtains and stabilizes the voltage from the loop, supplying power to the conditioning circuit and the sensor.

Besides the V/I conversion circuit, each part of the circuit has its own power consumption current. The core design idea of the two-wire transmitter is to include all currents within the feedback loop of the V/I conversion. The sampling resistor Rs is connected in series at the low end of the circuit, and all currents will flow back to the negative terminal of the power supply through Rs. The feedback signal taken from Rs contains the power consumption of all circuits.
