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.
