Product Introduction
I. Product Overview
Pressure instrument products are a combination of pressure sensors and gauges, with diverse variations and wide adaptability. They are used to monitor, control, and record parameters in various industrial and civil fields. The digital pressure gauge uses a strain-type pressure sensor, and the circuit part is equipped with a 24-bit AD processing chip, suitable for real-time monitoring in multiple on-site scenarios. It is widely used in fields such as petroleum, chemical engineering, electric power, metallurgy, environmental protection, as well as in home appliances, medical equipment, etc.
II. Application Features
- Combining with the company's base structure, it can adapt to many working condition scenarios.
- Different structures, operations, and programs can be customized according to customer requirements to meet customer needs.
- Flat membrane head: It is used for measuring the pressure of viscous media, avoiding measurement error problems caused by the media blocking the cavity.
- Universal head: It has universality and is suitable for gases, liquids, etc.
- Integrated type: It is suitable for scenarios with high requirements for safety, accuracy, etc.
- Full coverage of measurement ranges.
- High-precision strain measurement technology is adopted, enabling accurate pressure measurement.
III. Structure and Working Principle
Multiple bases with sensitive probes, combined with various gauges, use LCD or LED displays and buttons. The internally pasted strain circuit converts the medium pressure into an electrical signal, and then through digital high-precision amplification and other circuits, a professional analog-to-digital conversion IC is used, and through the MCU program, the purposes of display, query, communication, control, etc. are achieved.
IV. Operating Environment
