The BN-35CL is a streamlined 4 to 20mA current loop meter. It is specifically designed to be easily user-scaled and calibrated to almost any conceivable engineering unit, such as temperature, pressure, viscosity, or flow rates, etc. without requiring component changes. On site scaling and recalibration is facilitated by multiturn potentiometers that provide continuous adjustment within each of three header-programmable full scale ranges for span and zero offset. The display is shipped standard with red LEDs, but green LEDs or super bright LEDs for high ambient light environments are also offered. Display Segment Test and Hold Reading are standard features.
