SENEX DG1300-GE Flameproof Pressure Transmitter
DG1300-GE
The SENEX DG1300-GE is an explosion-proof, industrial-grade pressure transmitter engineered for hazardous environment monitoring, featuring a robust all-welded stainless steel construction, 4-20mA standard output, high-precision piezoresistive sensing technology, and Flameproof Ex d IIC T6 certification for demanding oil, gas, and chemical applications.
The SENEX DG1300-GE Flameproof Pressure Transmitter represents advanced piezoresistive sensing technology packaged within an ultra-durable flameproof enclosure designed for the most challenging hazardous environments. Engineered for continuous industrial process monitoring, the DG1300-GE utilizes imported high-precision piezoresistive sensor components coupled with reliable signal amplification circuits and precision digital temperature compensation across wide temperature ranges. Built with an all-welded stainless steel construction, it provides exceptional resistance to vibration, pressure spikes, lightning strikes, and radio-frequency interference (RFI/EMI). The unit converts measured liquid, gas, or vapor pressure into a standardized 2-wire 4-20mA DC current signal (or optional 0-5V, 0-10V, 1-5V DC voltage signals), making it seamlessly compatible with PLCs, DCS networks, secondary display meters, and automated process control loops. Operating reliably across extreme temperature conditions (-30°C to +85°C medium temperature and up to 250 MPa pressure ranges), the DG1300-GE features zero and span field adjustments, high overload protection up to 2x full scale, and exceptional long-term stability with minimal annual drift. It is certified Flameproof (Ex d II CT6) and Intrinsically Safe (Ex ia I/IIC T4/T6), delivering uncompromising safety, measurement repeatability, and operational efficiency across offshore platforms, petrochemical refineries, power generation facilities, pneumatic and hydraulic control machinery, and industrial automation networks.
Frequently Asked Questions
Q1: What media is the SENEX DG1300-GE pressure transmitter compatible with?
A: The DG1300-GE is compatible with a wide variety of liquids, gases, and steam media that are non-corrosive to 304, 316, or 316L stainless steel. For highly corrosive media, specialized material options or diaphragm seals are available upon request.
Q2: What explosion-proof certifications does the DG1300-GE hold?
A: The transmitter features dual explosion-proof certifications: Flameproof type Ex d I/II CT6 for containment of internal explosions in combustible atmospheres, and Intrinsically Safe type Ex ia I/IIC T4/T6 (which requires connection via safety barriers) for hazardous zone compliance.
Q3: Can the zero point and span range be adjusted in the field?
A: Yes, the DG1300-GE provides field-accessible zero and span potentiometer options, allowing technical operators to perform accurate calibration, range suppression, or zero offset corrections on-site without returning the unit to the factory.
Q4: How does the transmitter protect against electrical surges and environmental interference?
A: The DG1300-GE incorporates integrated lightning protection circuits, reverse polarity protection, over-current/over-voltage suppression, and shielding against high-frequency radio interference (RFI/EMI), ensuring continuous operation in harsh electrical environments.
Q5: What pressure types and ranges are available for this model?
A: The product supports Gauge Pressure (0 to 0.01 MPa up to 0 to 250 MPa), Absolute Pressure (0 to 0.1 MPa up to 0 to 250 MPa), and Vacuum/Negative Pressure (-0.1 to 0 MPa) options to match diverse process requirements.
