Manufacturer: Yokogawa Electric Corporation provides Yokogawa Processor Module SCP401 SCP451

Yokogawa Gas Density Detector GD40T/EJAF3T

The Gas Density Meter consists of gas density converter GD402 and gas density detector GD40.

The Model GD402 gas density converter and Model GD40 detector not only provide continuous measurement of gas density, but also several other valuable parameters, including specific gravity and molecular weight. The GD40 detector is designed for intrinsically safe and explosion-proof, explosion protected applications. It is designed to be virtually maintenance free for all accepted applications.
The Model GD402 is a rugged microprocessor-based converter designed in two versions to meet both general area and explosion-proof application requirements. In addition to the display of several key data items, the converter also provides the choice of three different means for calibration: automatic; semiautomatic and one-touch manual operation.
