EXECUTIVE ROOM THERMISTOR AND RTD SENSORS
ST-S*E, ST-S*EW SERIES
DESCRIPTION
The Precon ST-S*E and ST-S*EW Series Executive
Room Sensors provide precision room temperature
sensing for building automation systems. The active
sensing element is made of a highly stable, precision
thermistor material or platinum RTD.
FEATURES
• Lifetime warranty
• ±0.36°F (±0.2°C) thermistor accuracy
• ±1°F (±0.53°C) RTD accuracy
• Wide selection of thermistor and RTD curves
• Vented housing for quick temperature response
• Adaptable with many options
• Traditional beige or white covers
• Durable plastic housing and base plate
• Easy to mount to wall or back box
APPLICATION
The executive enclosure is designed to be wall-mounted
indoors where appearance is important. The separate
base plate may be mounted directly to the drywall
or on a standard electrical outlet box without adapters.
The cover is secured with tamper-resistant hex screws.
Where moisture is a concern, the moistureproof XB
option is required.
