Overview

The Ralston LC20 dual-sensor field gauge puts two pressure sensors in one LC20 housing. For example, LC20-GP2M-GB2M-00 has a 1,000 psi bottom sensor and a 5 psi top sensor, both on 1/4" male NPT. Per Ralston, the LC20 shows high and low values on-screen, switches between 15 engineering units or custom units, and includes FieldLab Desktop PC software for calibration, testing and live viewing. Sensor ranges vary by model.
