TE-631S-1 Johnson Controls Sensor

Overview

The Johnson Controls TE-631S-1 is a strap-mount pipe temperature sensor designed for accurate surface temperature measurement in commercial HVAC and building automation systems. By clamping directly onto pipe surfaces up to 2-5/8 inches in diameter, it eliminates the need for a thermowell, making installation fast and straightforward for hydronic heating, cooling, chilled water, and hot water piping applications.

Features

• Strap-mount design for quick, tool-friendly installation on pipes
• Eliminates the need for a thermowell, reducing installation time and costs
• Durable construction with a stainless steel insertion probe and PVC enclosure
• Passive, two-wire resistance output compatible with a wide range of building automation and DDC controllers
• Includes three cable ties for mounting to pipes up to 2-5/8 inches in diameter

Specifications

• Sensor Element: 1K Ohm Thin-Film Nickel RTD
• Sensor Accuracy: Plus or minus 0.34 degrees Fahrenheit at 70 degrees Fahrenheit
• Temperature Coefficient: Approximately 3 ohms per degree Fahrenheit
• Probe Dimensions: 1/4 inch outside diameter by 3 inches long stainless steel probe
