In the world of process control, accuracy, stability, and reliability are paramount. ISEN-EJCDP-B/C series, a top-tier Differential Pressure Transmitter designed to meet the rigorous demands of modern industries. This versatile instrument is engineered to deliver precise measurements for liquid, gas, or steam flow, as well as liquid level, density, and pressure, making it a comprehensive solution for a wide array of applications.
The core of the ISEN-EJCDP-B/C Differential Pressure Transmitter is its ability to output a 4-20mA DC signal that directly corresponds to the measured differential pressure. Its highly accurate and stable sensor not only measures differential pressure but also static pressure, with data accessible on the integral indicator or remotely via HART communications.
Uncompromising Performance and Accuracy
The ISEN series stands out for its exceptional performance specifications. The transmitter offers superior accuracy to ensure your processes are monitored and controlled with the utmost precision.
- Reference Accuracy: The ISEN-EJCDP-B model boasts a reference accuracy of ±0.075%, while the EJCDP-C model offers ±0.1%.
- Long-Term Stability: The transmitter is designed for durability and consistency, with a stability of ±0.1% of the span over a three-year period.
- Smart Communications: Featuring the HART FSK protocol superimposed on the 4-20mA signal, the device allows for remote set-up, self-diagnostics, and configuration, minimizing downtime and maintenance requirements.
- Quick Response: The amplifier damping constant is a swift 0.1 seconds and is adjustable up to 60 seconds, allowing for a tailored response time to fit specific process dynamics.
Robust Design for Industrial Environments
Built to withstand challenging industrial conditions, every component of this Differential Pressure Transmitter is selected for longevity and resilience.
- Wetted Parts Materials: The standard sensor body is made of 316L stainless steel, with options for Hastelloy C, Tantalum, and others, ensuring compatibility with various process fluids. The fill fluid can be specified as either silicone oil or fluorinated oil.
- Durable Housing: The amplifier housing is constructed from aluminum with an epoxy resin coat and is rated IP67 for protection against dust and water ingress.
- Operating Conditions: The transmitter can operate in ambient temperatures ranging from -40 to 85°C (-20 to 65°C with an LCD display) and handles working pressures up to 40MPa.
- Safety Features: For hazardous environments, the transmitter is available with NEPSI/ATEX explosion-proof certifications (Ex d IIC T6 and Ex ia IIC T4). It also includes a configurable failure alarm system (High, Low, or Hold mode) to enhance plant safety.
