Overview

This device is a high-accuracy industrial pressure transmitter designed for reliable measurement of gauge pressure in various liquids and gases. It offers exceptional performance with multiple accuracy options (as low as ±0.20% RSS) and is built with robust 316L stainless steel wetted parts for superior corrosion resistance.

The transmitter supports a 4–20 mA output with low power consumption (38 mA) and operates across a wide supply voltage range, making it compatible with diverse industrial systems. It withstands harsh conditions with IP66 / NEMA Type 4X enclosure ratings and a broad operating temperature range of 0 to 200 °F.

With a fast 300 ms response time, high proof pressure tolerance, and compatibility with various media—including water, oils, alcohols, and inert gases—it is ideal for process control, automation, and fluid monitoring applications. Its mounting is not position sensitive, simplifying installation in tight or complex setups.
