詳細(xì)介紹

ROOM HUMIDITY TRANSMITTER(GSH-420)

"GSH" Room Humidity Transmitters are intended for an electronic Humidity Transmitter to measure the Relative Room Humidity (RH) and converts the measurement into an electric signal.

This unit can be used with all system equipments that can receive output signals 4-20mA DC of the detector.

This Transmitter senses relative humidity by chargeable humidity sensing element which
varies electrical capacity depending on circumstantial relative humidity
Electronic sensing circuit varies signal into 4 ~ 20mA DC ( within 0 ~ 99% relative humidity )
Sensing Accuracy is ±3% within usable range of 20 ~ 90% RH.

SUPPLY VOLTAGE	: 24V AC / DC ±20%

FREQUENCY	: 50 or 60㎐
SENSING ELEMENT	: Integrated Circuity

POWER CONSUMPTION	: 0.35VA

SENSING RANGE	: 0 ~ 99%Rh

ACCURACY	: 20°C at 20~90%Rh within ± 3%Rh

OUTPUT SIGNAL	: 4 ~ 20mA DC

SENSING TIME	: Apprx. 20 sec


AMBIENT TEMPERATURE	: 1) On Operation : 0 ~ +50℃ 2) On Transportation & Storage : -25°C ~+65°C

AMBIENT HUMIDITY	: 1) On Operation : below 99%RH 2) On Transportation & Storage : below 95%RH

WIRING	: wires, 1.0㎟ or Shield Cable

WEIGHT	: 0.06Kg

HOUSING	: plastic case
PROTECTION CLASS	: IP 30

The element must not be touched and should be protected dust, water, spray and condensation.
The sensor element must not be exposed to organic solvents, sylphid bearing materials.
Do not use a DC test meter as this will damage the sensor element.
Select a location approx 1.5M above the floor.
The sensor location should also be reasonably clean and free from damp and condensation.
Fix with the bolts provided in pull box(50 × 100, 100 × 100)
To avoid the conductive current the wires should be separated from power lines.
Use the shield line when wiring

ROOM HUMIDITY TRANSMITTER(GSH-110)

"GSH" Room Humidity Transmitters are intended for an electronic Humidity Transmitter to measure the Relative Room Humidity (RH) and converts the measurement into an electric signal.

This unit can be used with all system equipments that can receive output signals 0-10VDC of the detector.

This Transmitter senses relative humidity by chargeable humidity sensing element which
varies electrical capacity depending on circumstantial relative humidity
Electronic sensing circuit varies signal into 0-10V DC ( within 0 ~ 99% relative humidity )
Sensing Accuracy is ±3% within usable range of 20 ~ 90% RH.

SUPPLY VOLTAGE	: 24V AC/DC ±20%

FREQUENCY	: 50 or 60㎐
SENSING ELEMENT	: Integrated Circuity

POWER CONSUMPTION	: 0.35VA

SENSING RANGE	: 0 ~ 99%Rh

ACCURACY	: 20°C at 20~90%Rh within ± 3%Rh

OUTPUT SIGNAL	: 0-10V DC (0 - 1V DC)

SENSING TIME	: Apprx. 20 sec


AMBIENT TEMPERATURE	: 1) On Operation : 0 ~ +50℃ 2) On Transportation & Storage : -25°C ~+65°C

AMBIENT HUMIDITY	: 1) On Operation : below 99%RH 2) On Transportation & Storage : below 95%RH

WIRING	: wires, 1.0㎟ or Shield Cable

WEIGHT	: 0.06Kg

HOUSING	: plastic case
PROTECTION CLASS	: IP 30

ROOM HUMIDITY TRANSMITTER(GRHO-420)

“GRHO“ Room Humidity Transmitter is intended for installing at the place of Heating, Ventilation facilities and specially at the place needed to be pleasantness of inside of building, and used to control and sense inside humidity possible to be used by connecting with Central control system.

SUPPLY VOLTAGE	: 15 ~ 30 V DC

OUTPUT SIGNAL	: 4 ~ 20 mA
SENSING RANGE	: 0 ~ 99%RH

SENSING ELEMENT	: Integrated Circuity

ACCURACY	: 20°C at 20~90%Rh within ± 3%Rh

WIRING	: 2 Wire

SENSING TIME	: Apprx1 min( Flexible depend on convection air and wall condition )

AMBIENT TEMPERATURE	: 1) On Operation : 0 ~ +70℃ 2) On Transportation & Storage : -15°C ~+50°C


AMBIENT HUMIDITY	: 1) On Operation : below 99%RH 2) On Transportation & Storage : below 95%RH

PROTECTION CLASS	: IP 30(EN60529)

WEIGHT	: 0.08Kg

Installing Location : Install at inside wall of good ventilating space
Prohibited Location : Inside corner, shelves, behind curtain and nearby reverse side of heat source
- Keep away from direct light and the end of wire tube of Sensor should be shielded to protect
any errors caused from ventilating air coming through wire tube.
Calibration : As adjusted on delivery from factory, do not change voluntarily
