Sensitive element pressure transmitter LFT6720

RS-485Modbus RTU4-pole

Product Overview
LFT6720 is an intelligent digital pressure transmitter for real-time pressure monitoring and alarm display. The instrument uses an LCD with red/green bicolor backlight to indicate normal, under-pressure and over-pressure conditions at a glance. Available in axial and radial configurations, it incorporates a high-overload glass micro-melting sensing element and a dedicated conditioning circuit to output standard MODBUS-RTU signals via RS-485.
