ST-209 Industrial Pressure Transmitter (Piezoresistive Silicon Core | 4-20mA / RS485 / 0-10V | Hirschmann Connector)
Product Overview:
The ST-209 Pressure Transmitter is a robust, high-precision instrument engineered for demanding liquid and gas pressure measurement in industrial automation. Built upon a high-sensitivity imported piezoresistive silicon pressure sensor core, the ST-209 incorporates an advanced, highly integrated bridge sensor signal conditioning ASIC alongside full-temperature-range digital compensation and non-linear calibration technologies.
It precisely converts fluid dynamic pressure into standard analog outputs (4-20mA, 0-10VDC) as well as industrial digital communications (RS485 Modbus, I2C). Equipped with a highly adaptable Hirschmann plug featuring a custom-molded waterproof and breathable design, the ST-209 provides outstanding durability, long-term stability, and cost-effectiveness across severe operating environments.
