EXECUTIVE ENCLOSURE:
The TE-200-AE space temperature sensor is available with a variety of
options that can be configured to all makes of Building Control Systems.
The TE-500-AE is a precision current loop temperature transmitter
featuring an optional three digit LCD indication of the temperature signal
that is being sent to the control system. The LCD display is factory
configured to display readings in either ¡æ or
¡ãF. This transmitter is also available with set point adjustment and
override push button.
The transmitter provides a high accuracy signal with excellent long term
stability, low hysteresis and fast response while being virtually immune
to power supply noise and input voltage fluctuations. All models operate
on a wide range of AC or DC power supplies.
