Description
The 301 compact pressure transmitter is designed for accurate and stable pressure measurement in industrial environments. It features a diffused silicon sensor core combined with a digital display to provide reliable and precise pressure readings.
The transmitter adopts an external vent hole design, which balances internal and external pressure to prevent diaphragm deformation and ensure higher measurement accuracy. This structure also helps the device resist instantaneous pressure shocks and maintain long-term stability.
Equipped with a 316L stainless steel connector, the transmitter offers excellent corrosion resistance and strong pressure resistance, making it suitable for measuring water, gas, oil, and hydraulic pressure. Its compact structure allows convenient installation in various industrial systems.
