Technical Parameters Overview

Professional-Grade Pressure Sensing Solutions

The SUP series pressure transmitter is designed by Xi'an Shenghongchuang Instrument Co., Ltd. specifically for harsh industrial automation environments。The product core integrates high-stability diffused silicon or ceramic piezoresistive sensor components，combined with precision temperature compensation algorithms and low-noise differential amplifier circuits，ensuring long-term stability of ≤±0.2%F.S./year within a wide temperature range（－10℃～＋70℃）。

This pressure transmitter supports multiple pressure types including gauge pressure，absolute pressure，and vacuum，with ranges covering from micro pressure －0.1MPa to ultra-high pressure 200MPa，and liquid level measurement up to 0～200 meters，meeting the differentiated needs of multiple industries such as petroleum，chemical，power，pharmaceutical，and water treatment for high-reliability pressure sensors。

Structurally，it adopts an all-stainless-steel integrated sealing process，and the 316L isolation diaphragm offers excellent corrosion resistance，making it compatible with the vast majority of mildly corrosive gas and liquid media；the M20×1.5 standard pressure port and Hirschmann electrical connection provide both installation convenience and field wiring safety；an optional compact integrated LCD display module and switch output function are available，facilitating on-site commissioning and status monitoring。
