Relative pressure transmitter GU27

absolutesensitive element4-20 mA

The GU27 is a precision pressure transmitter designed for advanced pressure measurement in intelligent manufacturing and high-end industrial applications. It supports gauge and absolute pressure measurement using a high-precision MCS sensing element and dedicated calibration circuitry, providing high accuracy across a wide temperature range, IP67 ingress protection and strong EMC performance.

Description
The GU27 pressure transmitter is suitable for demanding pressure measurement tasks in smart manufacturing and other industrial environments. By combining the MCS high-precision sensing element with a specialized calibration circuit, the transmitter achieves stable measurement results for both gauge (G) and absolute (A) pressure modes. The product is optimized for wide-temperature operation, robust sealing and electromagnetic compatibility.
