DW10 micro-differential pressure transmitter

The DW10 micro-differential pressure transmitter utilizes a high-precision sensor chip and intelligent embedded software algorithms to eliminate the zero drift issue of the sensor, accurately displaying minute differential pressures. The product's micro-differential pressure sensor boasts high sensitivity, ensuring high accuracy of ±1% of full scale throughout the entire measurement process. It features a customizable range function, allowing customers to adjust the required range on-site according to their needs, fully meeting on-site requirements. Additionally, it possesses characteristics of fast response and ultra-low range.

D2000 Differential Pressure Gauge

The D2000 series differential pressure gauges are elastic differential pressure instruments that utilize advanced spiral magnetic coupling technology and employ silicone diaphragms as sensitive elements. When air pressure (positive pressure, negative pressure, or differential pressure) acts on the two pressure chambers separated by the diaphragm, the diaphragm deforms. This deformation pushes the leaf spring equipped with a magnetic steel, causing the magnetically coupled spiral shaft to rotate up and down. Simultaneously, it drives the pointer to indicate the differential pressure reading on the instrument's dial, thereby achieving the purpose of measuring differential pressure.

DW605 Smart pointer differential pressure transmitter

The DW605 series intelligent differential pressure gauge utilizes advanced spiral magnetic coupling technology and a silicone diaphragm as its sensitive element. Combined with a built-in high-precision pressure sensor and signal processing circuit board, it forms an elastic differential pressure instrument that possesses both mechanical pointer indication and standard electrical signal output functions. When air pressure (positive, negative, or differential pressure) acts on two pressure chambers isolated by the diaphragm, the diaphragm undergoes deformation. On one hand, this deformation pushes the leaf spring equipped with magnetic steel, driving the spiral shaft to rotate through frictionless magnetic coupling, and thus driving the pointer to visually indicate the differential pressure reading on a clear 4-inch dial. On the other hand, the integrated high-stability sensor simultaneously and accurately captures the diaphragm deformation, and the built-in circuit board converts this physical signal into a standard industrial electrical signal (such as 4-20mA) for real-time output.

DW801 pressure transmitter

The DW801 pressure transmitter utilizes the DWPT series silicon pressure sensor, which is a high-stability silicon piezoresistive pressure measuring element with isolation. The pressure-sensitive chip selected is an ultra-stable silicon piezoresistive chip. It is composed of an oil-filled OEM pressure-sensitive element isolated by a corrugated diaphragm and housed in a stainless steel casing. All parts in contact with the medium are made of stainless steel, providing excellent corrosion resistance and long-term stability. The sensor undergoes temperature compensation across the full temperature range, ensuring technical indicators such as zero point, sensitivity, linearity, and stability are maintained over a wide temperature range. The measured pressure is transmitted to the pressure-sensitive chip through the isolation diaphragm and internal medium, achieving precise conversion from pressure to electrical signal. The advanced modular design and intelligent temperature compensation of the DW801 make it suitable for a variety of industrial environments

DW802 pressure transmitter

The DW802 pressure transmitter body adopts the DWPT series silicon core pressure sensor, which is a standardized high-performance pressure transmitter with characteristics of corrosion resistance, wear resistance, impact resistance, and vibration resistance. Its overload resistance can reach up to 100 times the range, completely solving the problem of poor overload capacity of other types of sensors in small ranges. In addition to having the range of general sensors, its most distinctive feature is its positive and negative gauge pressure function. The silicon core pressure transmitter has high accuracy, strong sensitivity, high frequency response, good corrosion resistance, stable performance, easy installation, and strong anti-interference ability. It is widely used in many fields such as petroleum, chemical, metallurgy, power, medical, automotive, environmental protection, industrial process control, etc., and can meet the pressure detection and control needs of different scenarios.
