At present, with the rapid development of China's industry, while maintaining sustained, rapid, and healthy development, there are still a large number of major projects that need to improve economic efficiency. At this point, technological transformation is needed, and product production also requires technical support Therefore pressure transmitter sensors have a significant market demand. With the development of economy and technology, market demand has increased and the future prospects are broad.

As for the structure of pressure transmitter sensors widely used in the current market, they mainly include microprocessors, sensors, digital to analog converters, memory and other devices, among which different devices play different automatic control roles. Sensors are mainly used to detect the measured signal, and the materials designed for specific applications are also different. As the core part of the entire device, the microprocessor is mainly responsible for comprehensive analysis and calculation of the relevant data collected by the device, as well as unit conversion, fault diagnosis, range adjustment, functional calculation and other operations of the detection signal. The function of memory is to configure data and programs in microprocessors. At present, most of the storage devices used by people have the functions of rewriting and adjusting.

The relevant converters are mainly responsible for the exchange of digital signals and analog signals. At the same time, the transmitter is also equipped with a backup power supply to avoid the loss of memory data in the event of a power outage. According to the different types of sensors used in intelligent pressure transmitters, they can also be divided into capacitive, diffused silicon strain gauge, and diffused silicon resonant types.

Today, we will introduce our Longlv Electronics PTL516 diffusion silicon pressure transmitter. The PTL516 diffusion silicon pressure transmitter adopts a precision machined core and a silicon diffusion injection process for sensitive components, forming a Wheatstone full bridge. An anti-interference resistor is built inside the bridge. When pressure is applied to the core, the resistance value is compared with the previous state to generate a MV signal proportional to the pressure. After being converted into a standard electrical signal by a secondary amplification circuit, the amplification circuit uses imported processing chips, high stability, high-precision silicon resistance full bridge, dedicated integrated circuit automatic calibration, strong temperature drift resistance, and the core is made of 316 stainless steel material, which is corrosion-resistant and high-temperature resistant.
