Digitron VAP Series of Panel Indicators

B324

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.

Two models are available:

The model A445 indicator and the model A448 indicator with single set point.

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.


Model P445 indicator and model P448 indicator with single set point.

The 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 INDICATOR

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).


Model V445 indicator, and model V448 indicator with single set point each with 2 ranges, 0-5V (1-6Vdc with offset). or 0-10V (1-11V dc with offset). Both instruments give out a nominal excitation voltage of 24V dc.

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
