Room Temperature/Humidity Sensor Model HTY7043D
General
Neosensor (two-wire 4-20mA output sensor) is a series of
electronic room sensors including temperature sensor
(Model TY7043D), humidity sensor (Model HY7043D), and
temperature/humidity sensor (Model HTY7043D).
Neosensor is coordinated in terms of design and dimension
with Neostat electronic room temperature/humidity controller.
Pt100 resistance thermometer sensor (JIS* C1604 Class A)
for temperature sensing element and polymer capacitive
humidity sensor (FP3developed by Azbil Corporation) for
humidity sensing element enhance accuracy and reliability of
Neosensor sensing. Neosensor is thus suitable for various
applications such as commercial building or other indoor
uses.
Note that the specification data of Neosensor the Pt100, 1-5V,
and 0-10V output sensors is not included in this document.
Refer to the following document.

Warnings and Cautions
WARNING Alerts users that improper handling may cause death or serious injury.
CAUTION Alerts users that improper handling may cause minor injury or material loss.
Signs
Alerts users possible hazardous conditions caused by erroneous operation or erroneous use. The symbol inside 
indicates the specific type of danger.
(For example, the sign on the left warns of the risk of electric shock.)
Notifies users that specific actions are prohibited to prevent possible danger. The symbol inside graphically
indicates the prohibited action.
(For example, the sign on the left notifies that disassembly is prohibited.)
Instructs users to carry out a specific obligatory action to prevent possible danger. The symbol inside graphically
indicates the actual action to be carried out.
(For example, the sign on the left indicates general instructions.)
CAUTION
Use the product under the operating conditions (temperature, humidity, power, vibration, shock, mounting direction,
atmospheric condition, etc.) as listed in the specifications.
Failure to do so might cause fire or device failure.
Use the product within the rated operating ranges as listed in the specifications.
Failure to do so might cause device failure.
Before wiring, be sure to turn off the power to the product.
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
All wiring must comply with applicable codes and ordinances.
Do not disassemble the product.
Doing so might cause device failure.
Dispose of the product as industrial waste in accordance with your local regulations.
Do not reuse all or part of this product.
IMPORTANT:
Operating conditions such as wind velocity and load resistance affect Neosensor sensing accuracy. Refer to
Specifications and Installation sections for its installation.
Product sensing accuracy is preset before shipment. Output of the product, used even in normal air, may be
shifted depending on the operating conditions. Periodic inspection therefore is recommended.
Corrosive gas or organic solvent may shift the humidity output or damage the humidity sensing element.
Before using the product (Models HY7043D, HTY7043D) in abnormal atmosphere, consult with our sales
personnel.
