TE-637DP-1 Surface-mount
Duct Temperature Sensor
The TE-637DP-1 provides temperature sensing in a compact surface-mounted unit for use inside economizer rooftop systems. The unit housing is a durable plastic enclosure that installs easily to the duct surface. A protective membrane prevents sensor contamination due to dust, dirt, and insects.
The TE-637DP-1 has a thermistor temperature sensor with a negative temperature coefficient, and a reference resistance of 2.2k ohms at 77°F (25°C).

roduct Overview
P
The TE-637DP-1 outputs temperature signals for use in rooftop economizer applications. The TE-637DP-1 is suitable for use with a Johnson Controls Direct Mount Economizer (DME) Controller.
The TE-637DP-1 is a durable, yet cost-effective solution for sensing temperature. It is housed in an easy-to-install plastic enclosure, which speeds commissioning time and reduces cost.
IMPORTANT: The TE-637DP-1 is intended to provide an input to equipment under normal operating conditions. Where failure or malfunction of the TE-637DP-1 could lead to personal injury or property damage to the controlled equipment or other property, additional precautions must be designed into the control system. Incorporate and maintain other devices, such as supervisory or alarm systems or safety or limit controls, intended to warn of or protect against failure or malfunction of the TE-637DP-1.
IMPORTANT: Le TE-637DP-1 est destiné à transmettre des données entrantes à un équipement dans des conditions normales de fonctionnement. Lorsqu'une défaillance ou un dysfonctionnement du TE-637DP-1 risque de provoquer des blessures ou d'endommager l'équipement contrôlé ou un autre équipement, la conception du système de contrôle doit intégrer des dispositifs de protection supplémentaires. Veiller dans ce cas à intégrer de façon permanente d'autres dispositifs, tels que des systèmes de supervision ou d'alarme, ou des dispositifs de sécurité ou de limitation, ayant une fonction d'avertissement ou de protection en cas de défaillance ou de dysfonctionnement du TE-637DP-1.
