The A445 Panel Indicator comes from the A440 SERIES of CURRENT LOOP INDICATORS. Digitrons A440 Series current loop indicators are designed for use with any current loop sensor, which gives out a dc current in the range 0-20mA, or 4-20mA.
0mA or 4mA zero inputs are selectable, with further offset adjustment for sensor calibration (using jumper links). The instrument gives out a nominal excitation voltage of 24V dc and can also be used as a repeaters on loops, which are already powered.
Digitrons VAP Series offer a range of high accuracy performance panel meters designed for use with pressure transducers, high voltage transducers and current loop sensors. Please check the datasheet for full information.
Highly accurate performance
Large LED display
Easy to use
All models incorporate a decimal point position selection and continuous scaling of gain, from full scale > 250 to < 1999, using jumper links, zero and gain adjustment control
The VAP Series are supplied with a set of standard engineering units for customer use. The appropriate symbol should be fixed to the front panel.
