Product Description

1. Description

JW-PM03X(JY02) Sanitary flush diaphragm pressure transmitter with 316L stainless steel diaphragm, anti interference protection, multiple output signals and IP65 to IP68 options for food, beverage, pharmaceutical and viscous media pressure measurement.

2. Product Overview

JW-PM03X(JY02) The flush diaphragm pressure transmitter is designed for sanitary pressure measurement in applications where cleanliness, anti-clogging performance and stable signal output are required. The sensing diaphragm is welded directly to the front of the process connection, allowing the transmitter to detect pressure without dead zones or blocked cavities.

Using a silicon sensing chip and dedicated digital circuit, the transmitter provides signal amplification, linear compensation, anti interference processing and surge leakage protection. It converts pressure into standard industrial signals for reliable integration with PLCs, data loggers, control systems and IoT monitoring platforms.

This product is especially suitable for food processing, beverage production, brewing, pharmaceutical manufacturing, sanitary pipelines and viscous media measurement.
