Model GD402 Gas Density Meter

IM 11T3E1-01E

7th Edition (YK)

Introduction

The GD402 gas density meter and the GD40 detector not only provide continuous measurement of gas density, but also several other valuable parameters, including specic gravity and molecular weight. The GD40 detector is designed for intrinsically safe and ame-proof, explosion protected applications. It is designed to be virtually maintenance free for all accepted applications.

The 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; semi-automatic and one-touch manual operation.

Before use, read this manual thoroughly in order to fully realize the capabilities of the Meter. The topics and information that require special attention when handling the product are given in the text of this manual along with cautionary notes - WARNING or CAUTION - which reect the importance of the information.

1.1.2 GD40G, T, V, R Detector

l Material exposed to gas

SUS 316 stainless steel, Acrylonitrile Butadiene Rubber and Fluorine-contained Rubber

(O-ring)

l Ambient conditions

Temperature: -10 to 60 °C (14 to 140 °F)

Humidity: 5 to 95 %RH

Installation: Pipe-mounted or on panel

Construction: Explosion-proof and Intrinsically safe. (See 1.1.1 “System Components”)

Though the detector construction makes it relatively insensitive to sudden changes in

the gas temperature, extra precision can be achieved by keeping ambient temperature conditions as constant as possible. In measurements where optimum precision is required it is therefore not recommended to install the detector in an outdoors environment, especially not if such installation is prone to direct sunlight.

l Finish

Cover: Equivalent to Munsell 0.6GY3.1/2.0

1-5

Case: Equivalent to Munsell 2.5Y8.4/1.2

l Weight

Approximately 7 kg (with pipe mounting bracket)

l Detector unit

When the system is ordered to be used as a hydrogen purity meter, an optional pressure

transmitter is required for pressure compensation.

• If /EJAJ1, /EJAF2, /EJAF3 or, /EJAF4 are ordered, the detector unit and the

pressure transmitter and the tubing in between will all be integrated on a single mounting plate. This allows the space where the pressure transmitter is normally mounted to be used effectively for other purposes.

1.1.3 GD402G, T, V, R Converter

l Display

Reading: Digital (6 digits maximum; resolution: 0.0001 kg/m3)

Data items shown:

Measured value: Always on display.

Alarm indications: Abnormal concentration, abnormal pressure range of input and abnormal

value of calibration.

Parameters for calibration: Time of calibration, settling time, starting time of calibration and

calibration cycle

Self-diagnostic indications: Sensor oscillation shutdown, abnormal oscillation frequency of

sensor, failure in sensor temperature detection, failure in A/D conversion stage and memory failure.

Alarm settings: The contact state can be set to either “normally open (NO)” or “normally

closed (NC)” depending on the needs of the application.

Temperature: Temperature of gas being measured

2. INSTALLATION, WIRING AND PIPING

The GD402 Gas Density Meter is thoroughly inspected at the factory and carefully packed to ensure the equipment does not suffer any damage during transportation. The package should also be handled with care when unpacking to prevent the equipment from undergoing severe mechanical shock. After unpacking, visually check the equipment to ensure that it is free from any damage.

Although the detector has no controls on it, it may need to be accessed for inspection or for other reasons. Install the detector in a location as close as possible to where the gas is sampled and where maintenance can be easily carried out. The converter has a display with controls on it; thus, you should install it so that the keys are positioned directly in front of you when working.

Note that there must be a clearance of at least 400 mm at the back of the converter GD402G, GD402T, GD402V and GD402R since cables are wired to the back by removing the screwed rear cover.

2.1 Installing the Detector

The GD40 detector is an explosion-proof with intrinsically safe sensor instrument. Install the detector in a location where the following conditions are satised.

2.1.1 Selecting the Location

l Explosion-proof construction

Before installing the detector in an explosion-hazardous area, ensure that the area conforms to the explosion-proof code noted above.

l No corrosive gases

Corrosive gases are not desirable because they may damage the electrical components in the detector.

l Slight mechanical vibration

Although the detector is vibration-resistant, vibration may loosen the connections of the external wiring.

l No exposure to direct sunlight

Exposure to direct sunlight may raise the temperature in the detector to abnormal levels, and should therefore be avoided. Note that such abnormal temperature levels can also result from heat irradiated from high-temperature equipment around the detector.

l Humidity maintained between 5% and 95 %RH

Avoid choosing a location that is likely to be exposed to abnormally high or low humidity over a prolonged period. It is recommended that the detector be used at a humidity between 25% and 85 % RH.

l No exposure to rain water

Even though the detector is rainproof, whenever possible install it where it is protected from water splashes. The reasoning for this is that the detector cover may need to be removed for maintenance or for other reasons.

l Altitude of installation site is lower than 2,000 m.

2.2 Installing the Converter

The GD402 converter comes in either the non-explosion-protected Model GD402G or explosionprotected Model GD402T, V, R (explosion-protection code: Refer to 1.1.1). Choose the Model GD402T or V or R if the converter is to be used in a hazardous area.

2.2.1 Selecting the Location

l Ease of operation

Select a location where you can easily view the readings on the display and work with the keys. Installing the converter closer to the detector will ease your maintenance work, including calibration.

l Explosion-proof construction

When installing the converter in an explosion-hazardous area, ensure that the area conforms to the explosion-proof code noted above.

l No corrosive gases

Corrosive gases are not desirable because they may damage the electrical components in the converter.

l Slight mechanical vibration

2-5

Although the converter is vibration-resistant, vibration may loosen the connections of the external wiring.

l No exposure to direct sunlight

Exposure to direct sunlight may raise the temperature in the converter to abnormal levels, and should therefore be avoided. Note that such abnormal temperature levels can also result from heat irradiated from high-temperature equipment around the converter. If the converter is likely to receive direct sunlight and the temperature in the converter will likely exceed the operating limits, attach a hood (optional).

l Humidity maintained between 5% and 95% RH.

Avoid choosing a location that is likely to be exposed to abnormally high or low humidity over a prolonged period. It is recommended that the converter be used at a humidity between 25% and 85 % RH.

l No exposure to rainwater

Even though the converter is rainproof, whenever possible install it where it is protected from water splashes. The reasoning for this is that the converter cover may need to be removed for maintenance or for other reasons

l Altitude of installation site is lower than 2,000 m.
