Overview
The JEF200 series pressure transmitter is a pressure transmitter independently developed by our company. It consists of a diffused silicon pressure sensor and a high-performance dedicated amplification circuit housed in a stainless steel shell. The sensor has been compensated for zero point and sensitivity over a wide temperature range. Electrical connections are available in both Hirschmann plug-in and cable outlet options. This product features a compact structure, stability, and reliability, and is widely applicable for pressure measurement of fluids compatible with stainless steel materials, such as water, oil, and gas.
Features
1. 316L stainless steel diaphragm with digital display. IP65 rating, compact design, 4-20mA high precision, and excellent long-term stability.
2. Measureable gauge pressure, absolute pressure, and sealed pressure; 316L stainless steel diaphragm structure, high precision, full stainless steel construction.
3. Strong anti-interference and long-term stability, shock and vibration resistance, suitable for measuring at room temperature, capable of long-term stable operation.
4. Diverse in form and structure, easy to install and use.
5. Wide measurement range, capable of measuring absolute pressure, gauge pressure, and sealed gauge pressure.
