Product Short Description
Product Introduction
The GE DT07H-10-6PN is a robust industrial pressure transmitter module designed to convert gas, liquid, or steam pressure signals into a standardized 4-20 mA analog output for seamless integration with distributed control systems (DCS), programmable logic controllers (PLC), and turbine control systems like GE Mark IV/Mark V. It integrates a stainless steel sensing element, precision signal conditioning circuitry, and a 6-pin Deutsch DT connector for reliable field wiring. The module features ±0.5% full-scale accuracy, a wide operating temperature range of -40°C to +85°C, and IP67 protection against dust and water immersion, making it suitable for harsh industrial environments. It operates on 24 VDC power, incorporates reverse polarity protection, and uses industrial-grade materials for long-term stability in continuous process applications. It is fully calibrated at the factory, requires minimal field adjustment, and complies with industrial standards for pressure measurement and signal transmission, ensuring consistent performance in critical industrial control loops.
