Pressure Transmitter for Heat Exchangers – EDN.337

The EDN.337 pressure transmitter is specifically designed for use in heat exchanger systems. All wetted parts are constructed from stainless steel, ensuring excellent corrosion resistance and durability. The core sensing element is a piezoresistive silicon pressure sensor, carefully selected and engineered to provide reliable performance under the varying thermal conditions typical of heating and cooling systems.

To keep pace with the demands of the modern electronics industry, the signal processing chip integrates the latest technology, ensuring optimal signal amplification. The internal electronics are engineered to minimize the effects of noise, bursts, insulation interference, and surges, ensuring high signal fidelity and consistent accuracy in measurement.

Manufactured under strict process and quality control, the EDN.337 ensures excellent reliability and stability even when transmitting analog signals, which are typically more susceptible to external interference. A meticulous calibration process further enhances the transmitter’s precision, making it highly suitable for dedicated applications in heat exchangers.

During development, the EDN.337 was rigorously benchmarked against both domestic and international counterparts through comparative performance tests. These tests confirmed the product’s superior quality and precision, validating its design as a dedicated pressure transmitter for control and instrumentation in heat exchanger environments.

Main Application:

• Heat Exchanger Systems

Additionally, based on the installation environment, diaphragm seals or chemical flanges can be optionally integrated to ensure smooth and superior performance under specialized mechanical conditions.

The EDN.337 guarantees high accuracy at 0.5% F.S., even under the most demanding field conditions. It is compatible with a wide range of process connections and electrical plug types, meeting the diverse needs of industrial applications. By adopting the EDN.337, your operation can benefit from enhanced process stability, improved measurement precision, and higher product quality in production environments.
