Display Features
The Yokogawa F9342L-02 shows pressure values with up to five significant digits. Its segmented design includes dedicated annunciators for bar, psi, and other common units. The reflective LCD requires no backlight, reducing overall transmitter power consumption. The display updates reliably even at the minimum loop current of 4 mA.
Local Configuration
The push-button interface enables full transmitter configuration without a communicator. The Yokogawa F9342L-02 allows users to adjust zero and span values directly in the field. Technicians can navigate through configuration menus using simple button sequences. This local capability reduces commissioning time and eliminates handheld device dependency.
Integration and Mounting
This display module connects to the CPU board through a flexible ribbon cable. The Yokogawa F9342L-02 sits behind the transmitter’s cover window for environmental protection. Its low profile does not increase the overall transmitter dimensions. Field personnel can replace the display without recalibrating the instrument.
Application Scenarios
Maintenance teams use this display for quick process checks during routine rounds. It aids in troubleshooting and verifying transmitter output during startup. The Yokogawa F9342L-02 proves essential in locations where handheld communicators are unavailable.
