Diffused Silicon Pressure Transmitter
Diffused Silicon Pressure Transmitter
The Diffused Silicon Pressure Transmitter is manufactured using state-of-the-art isolated diffused silicon
sensing elements and high-quality integrated circuits. Combining excellent performance with
cost-effectiveness, it is designed to meet the demands of a wide range of industrial applications.
The transmitter incorporates precision diffused silicon sensing technology, advanced mechanical processing,
temperature compensation, and analog signal conditioning technologies, ensuring high accuracy, long-term
stability, and reliable performance. Its main circuitry is fabricated with advanced materials and processes,
while the fully sealed construction provides complete isolation from the external environment.
Designed for harsh industrial environments, the transmitter offers excellent resistance to moisture, water
ingress, explosion hazards, corrosion, dust, and other adverse operating conditions. By selecting appropriate
process connections and wetted materials, it can accurately measure highly corrosive media, high- and
low-temperature fluids, as well as viscous process media.
With its robust design, outstanding reliability, and versatile application capability, the Diffused Silicon
Pressure Transmitter is an ideal solution for pressure measurement and control in industries such as
petrochemicals, water treatment, power generation, food processing, pharmaceuticals, and general
industrial automation.
Features
* Small size and light weight: Only 1/3 the size and 1/5 the weight of a capacitive pressure transmitter.
* High accuracy and good stability: Stable and reliable silicon piezoresistive chip.
* Reliable circuitry and fast response.
* Advanced diaphragm isolation technology: Employs advanced diaphragm/oil-filled isolation technology; minimal oil filling ensures excellent pressure transmission.
* Intelligent interface and easy expansion: The intelligent type can be easily connected to various intelligent display controllers, frequency converters, PLCs, DCS, PCs, PDAs, etc.
