Vaisala Veriteq VL 4000 Voltage and Current Loop Data Loggers

Vaisala Veriteq VL 4000 Voltage + Current Loop Data Loggers are highly accurate self-powered 12-bit data loggers that provide high-accuracy recording of 4-20 mA current loop or DC voltage signals with four input channels. You can record data into user-defined measurement units and in adjustable logging intervals, allowing up to a 10-year recording capacity. Perfect for recording signals from transducers, transmitters, and senors, they can be used by researchers, plant operators, test & measurement engineers and quality control personnel.

A current loop XPS excitation control switch on the logger allows for efficient powering of external transducers.

     Features

    		 
    ​
    Easy to set up and use - Just connect two wires from your transducer, transmitter or sensing device to your logger's input channel, then fill out a simple form in Vaisala Veriteq Spectrum software to describe preferred scaling and measurement.

    Various uses - 4000 Series recorders are ideal for interfacing to any equipment supplied with dc voltage or 4-20 ma current loop outputs, including transducers, transmitters and sensors for monitoring pressure, flow, fluid level, PH, electrical properties, moisture, gas concentrations and more.
