GS4400/GS4500

The GENSPEC GS4400/GS4500pressure transmitters are designed to meet the operational requirements of demanding pressure measurement applications providing fast and noise-free point to point communication in industrial applications in pressure ranges up to 0-1500 bar.

The GS4400 provides a half-duplex digital RS-485 output signal and 0-5V analogue output, while the GS4500 provides a Modbus RTU output signal and 0-5V analogue output.

All versions utilise ESI’s outstanding Silicon-on-Sapphire sensor featuring all titanium wetted parts for excellent media compatibility and rugged, reliable performance . They provide high stability and repeatability and can be configured to suit a multitude of applications. Each transmitter can be allocated a unique device address and connected in series to other transmitters and devices on the same communications link. The GS4400/GS4500 are also compatible with the ESI-USB software.

Digital accuracy is 0.15%, with an exceptional overpressure limit. All models are supplied with integral 1/4” BSP male with a range of other process connection options. The titanium alloy wetted parts offer unbeatable corrosion resistance and the M12 electrical connection is rated IP67 for high levels of environmental protection.
