Model
1250: Indoor Temperature / Relative Humidity Network
Transmitter
 Datasheet
 XIF File
Description
The Model 1250 is an indoor temperature and relative
humidity transmitter that is self-contained.
It contains the temperature sensor, humidity sensor, microprocessor,
measurement electronics, and network communication interface.
The temperature and humidity sensors are located away from
the electronics in a separate compartment.
This allows a more accurate measurement of air temperature and humidity
for two reasons. One, it isolates
the sensors from temperature generated by the electronics.
Two, it provides excellent airflow around the sensors.
The
sensor and configuration information is communicated to other devices via the LonWorks
communication protocol. This allows
multiple sensors to be used over a simple four-wire bus installation.
