VAP Series

VAP Series Digital Panel Meters

Digitron’s VAP Series offer a range of high accuracy performance panel meters designed for use with pressure transducers, high voltage transducers and current loop sensors.

Features include

Highly accurate performance
Large LED display
Easy to use
Controller model
Superb value
Compact design
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

A440 Series Current Loop Indicators

Digitron’s 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). Both instruments give out a nominal excitation voltage of 24V dc and can also be used as repeaters on loops, which are already powered.

P440 Series Pressure Indicators

Digitron’s P440 Series pressure indicators are designed for use with pressure transducers with a full-scale output 100mV or other strain gauge device.

These instruments give a 10V DC excitation voltage and can be adjusted to give full-scale indication for other than 100mV using jumper links, zero and gain adjustment control.

V440 Series Bridge Transducer Indicators

The V440 series transducer Indicators are designed for use with any 3 terminal transducer which requires a nominal + 24V DC excitation voltage and gives out a signal in the range 0-5V or 0-10V DC (1-6V, 1-11V DC with offset).

Reliability

All models are subjected to detailed inspection and a rigorous testing programme before being calibrated. All models are also supplied with a 12 month warranty on parts and labour.
