Compact Pressure Transmitter | MEMS Silicon | Hydrogen Resistant | 0-60MPa | Ex ia/db IIC T4~T6
This compact pressure transmitter adopts advanced MEMS monocrystalline silicon strain technology with a built-in digital conditioning chip for high-precision pressure measurement. Its integrated stainless steel elastic body design features no welds and no leakage risk, ensuring long-term stability. The unique pressure-resistant structure provides excellent overload capacity (3x full scale) and multi-layer stress isolation reduces installation stress effects on accuracy. It is resistant to hydrogen embrittlement and permeation, making it ideal for hydrogen measurement. With a 1ms response time, low temperature drift (<0.015%FS/°C), and wide operating temperature range (-40~125°C), it offers gauge, absolute, and vacuum pressure types from 0~-0.1MPa to 0~60MPa. Output signals include 4-20mA, 0-5V, 0-10V, and 1-5V. Explosion-proof ratings include Ex ia IIC T4~T6 Ga and Ex db IIC T4~T6 Gb.
